Updated: Bleeding edge Ubuntu 4.10.0-5.7 kernel with 17.04 pseudo Alpha 2 ISO

UpdateThis page refers to earlier work and my latest ISOs and kernel upgrade scripts can be downloaded from my latest post.

Please note my blog is intended to be the 'dynamic' update content partner to my 'static' core content pages on my website. This particular post relates to my http://www.linuxium.com.au/how-tos/runningubuntuontheintelcomputestick page where I've created some Ubuntu ISOs whose purpose is to better support Intel Atom based devices. 

Whilst Ubuntu flavours released their second alpha of the Zesty Zapus (to become 17.04) today, Ubuntu continues with daily releases until the final beta in March (see https://wiki.ubuntu.com/ZestyZapus/ReleaseSchedule).

So I've created a pseudo Ubuntu Alpha 2 based on the official daily release for the 27th January which is the same date as the released Ubuntu flavour Alpha 2 releases and I've created a Lubuntu Alpha 2 based on the official release.

I've replaced the included kernels with my latest bleeding edge patched Ubuntu 4.10.0-5.7 kernel from Canonical which is based on the mainline 4.10.0-rc5 kernel. I've added Pierre-Louis Bossart's latest patches for the HDMI LPE audio driver and RT5640 audio support, together with Hans de Goede's patches for PMC platform clocks, PMIC I2C bus semaphore implementation and Power Management IC AXP288 support for Bay Trail and Cherry Trail devices.

Also included is additional wifi support including Bastien Nocera's RTL8723BS driver, support for the Atheros AR6004 HW3.0 driver used on the Dell Venue Pro 11 Baytrail, and Broadcom 4330, 43430 and 43340/43341 support. Bluetooth support includes Larry Finger's code for RTL8723BS with a patch from Laszlo-Fiat.

Finally I've included patches to fix various issues like the CUBE iwork8 Air tablet getting stuck on booting and the persistent freezing issue with a patch from Mika Kuoppala. If freezing still persists Len Brown suggests adding "intel_idle.max_cstate=2" as a kernel boot parameter which enables Core-C6 but disables module/package-C6 as he has found this is still required for the ASUS Transformer Book T100 Chi.

My latest kernel and ISOs address a lot of outstanding issues when trying to run Ubuntu on Intel Atom based devices. For the first time ever I've now seen working bluetooth on Bay Trail Realtek chip based devices like the Meegopad T02 and Star Cloud PCG02U. Also bluetooth on Broadcom chip based devices like the Tronsmart Ara X5 works as does HDMI audio on the Mini Neo Z83-A.

Some peculiarities from being an Alpha release exist such as the installation not recognizing previously installed OS so until this is fixed in the official ISO it is best to use 'Something else' and manually partition as per your needs for example when dual booting with Windows. But I have fixed the installation error that prevented an LVM installation (with/without encryption) using the official ISO.  Prior to embarking on an encrypted LVM installation you should first open a terminal session and turn off swapping using the command 'sudo swapoff -a'.

Overall these are the closest to a fully working Ubuntu ISOs for a wide range of Intel Atom devices from stick to mini PCs and tablets than anything previously released. Note I recommend installing the ISO rather than using the kernel update script as it includes the necessary 'userland' files for audio, wifi and bluetooth. By simply performing a kernel upgrade you may not get the same level of functionality that a fresh install from my ISO will provide.

The links below (in red) have been updated for downloading the latest i.e. version 3.

To try an ISO download it from the link below (in red) and write it to a USB using either 'Rufus' in Windows or 'dd' in Linux.


Ubuntu 17.04 pseudo Alpha 2 (Version 4 superseded)
Ubuntu comes with everything. All the essential applications, like an office suite, browsers, email and media apps come pre-installed and thousands more games and applications are available in the Ubuntu Software Centre.



Lubuntu 17.04 Alpha 2 (superseded)
Lubuntu is a fast, energy saving and lightweight variant of Ubuntu using LXDE. It is popular with PC and laptop users running on low-spec hardware.



To turn on wifi for mini PCs with Broadcom wifi chips it is often necessary to reload the driver. In a terminal window enter 'sudo modprobe -r brcmfmac' followed by 'sudo modprobe brcmfmac'.

Because my ISOs include a patched kernel to address the missing functionality of the official ISOs it means no automatic Ubuntu kernel updates are provided. Consequently I've also developed a manual patching process where a script can be downloaded and then executed to update the kernel to match the official releases. As such my kernel update scripts are not intended to update the kernel installed on other Linux installations. Primarily because you would be missing the 'userland' files required for audio, wifi and bluetooth and the resultant environment may be unstable or worse. 

For the sake of completeness I'm including the kernel upgrade script which matches the kernel version included in my ISOs. The normal requirement would be to upgrade the existing installed kernel (created from my ISO or as a result of a previous upgrade) to the later version provided by the script. To use you would download the shell script and after making it executable (enter 'chmod 755 <script>') you then install it as 'root' (by entering 'sudo <script>'). Once the script has finished executing the device would need to be rebooted to use the updated (patched) kernel.

4.10.0-5.7 (Version 4) (superseded)

    1. Thanks for the 'pastebin'. For the wifi issue please copy across the Windows driver file stored in NVRAM. For example look for a file something like '/sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113' and then copy it using 'cat /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 > /lib/firmware/brcm/brcmfmac43430-sdio.txt'. Substitute the NVRAM filename your find for the 'nvram-*' filename in the command. Also please try version 2 to see if this fixes audio.

    2. I didn't understand well what you asked me, maybe because I forgot to tell you that I deleted the (crappy) original windows 10 installation of that chinese notebook and I reinstalled a new clean w10 with every driver needed for every device. However a friend of mine (bless him) provided me with this: https://github.com/parkerlreed/Asus-T100TA-EFI/blob/master/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113
      and told me to save it's content in a temp file to use in the first part of your command:
      "cat temp > /lib/firmware/brcm/brcmfmac43430-sdio.txt" but the wifi still remains dead.
      The new kernel didn't helped with the audio, still mute.

      p.s. I also tried the overwriting of "brcmfmac4330-sdio.txt" because that's the file the tab autocompletes in that folder.

      p.p.s. at some point I made something huge because I couldn't do anything even with sudo commands (permission denied everywhere), I rebooted with gui and the os was not loading (tried some workarounds to fix "The system is running in low-graphics mode" but I failed), so I installed lubuntu and lost the win partition.

      Delete
    3. After copying the file with the command "cat temp > /lib/firmware/brcm/brcmfmac43430-sdio.txt" did you then enter 'sudo modprobe -r brcmfmac' followed by 'sudo modprobe brcmfmac' as this seems to be required to start wifi?

      Sound is a separate issue and I am working on that at the moment.

    4. Yes of course, no networking device.

    On my Asus Vivotab 8 M81C, the wifi is now working (previously not working on 16.10 32bits) but the installation is stuck, I got an error status 1 when the installation is configuring the grub-amd64. Maybe the 32bits version of Ubuntu 17.04 like 16.10 I have installed may work.. please release the 32 bits version I could test it on my tablet. :)

  11. Excellent iso !! Installing Linux on the Asus X205TA used to be a pita, but almost everything works out of the box !

    I found some issues that have plagued the machine for a long time that also seem to affect this iso:
    - wifi breaks after suspend (a workaround I use is blacklisting btsdio)
    - touchpad breaks after suspend (a workaround I use is to reload elan_i2c)
    - sometimes suspending leads to inability to resume (which, btw, can only be done by clicking the touchpad)

    Sadly for the last point I have not yet found a fix or workaround, and it's a pretty serious point…

    dmesg after suspending (and thus breaking touchpad and wifi): http://sprunge.us/QMIE

    (on a sidenote, headphones are not working yet. But maybe this is because Pierre Bossart fixed this pretty recently)

    1. In the past I have disabled suspend although this is more of a work around than a fix. As I don't have an Asus X205TA its difficult to guess what will and won't work. Is there a specific fix I should look to include for working headphones on that device?

      Delete
    2. Yeah disabling suspend pretty much the only safe choice if you're working on something important, which is a pity.

      I think headphone output was fixed by these commits (still no jack detection though):

    >>>For the wifi issue did you copy across the Windows driver file stored in NVRAM? The file should look something like '/sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113' and you should copy it using 'cat /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 > /lib/firmware/brcm/brcm/brcmfmac43241b4-sdio.txt'. Substitute the NVRAM filename your find for the 'nvram-*' filename in the command.

    OK, I did exactly that, using the version 3 alpha2.
    Yes, I got the wifi working as per the above, copy the NVRAM file over and redo modprobe. The filename for the NVRAM matched what you had above.

    I checked other functionality: This is an Acer Switch 10, model is SW3-013 , NT.MX1AA.007.
    Bluetooth: not working, and it might be the same broadcom device as the wifi.
    Touchscreen: working touchpad and keyboard: working.
    battery indicator: working
    audio: not working.

    2. Sure it did!

      I used the new version 3 revision 2.
      The Bluetooth worked right away.

      The wifi function again worked after copying the NVRAM over and re-do of modprobe.

      Again, I have uploaded dmesg of today's session at
      http://paste.ubuntu.com/23918940/

      and I noticed that pastebinit of the NVRAM didn't offer you anything useful becuase of unprintable chars in the file, so I used uuencode.

      Here's a 64-bit uuencode of the nvram-74b00bd9-805a-4d61-b51f-43268123d113 file from /sys/firmware on this tablet PC:
      http://paste.ubuntu.com/23919097/
      You should be able to reverse the uuencode at your end if you need the file.

      functionality:
      the wifi works normally after copying over the nvram and redo of modprobe.

      the bluetooth seems to work normally.
      I paired to a BT keyboard and used the keyboard.
      I paired to an audio device and used it to get some sound output, and the audio device was controllable through the normal sound settings.

      I tried to pair to a BT mouse, that failed, but I think it's the mouse that is incompatible. It is called rocksoul BT mouse (ms-102ssbt). I read where people have trouble with this mouse with Apple OSx I can't find any other BT mice in the house to try. If I find other BT input device, I will try it.

    3. I did find another Bluetooth device to test with, it looks like a pen and acts like a mouse, it's called penclic mouse, and it pairs and works. I think the Broadcom bluetooth works fine.

  17. For touchscreen not behaving properly with rotated screen, you may need to use xinput to change the coordinate transformation matrix.

    https://wiki.ubuntu.com/X/InputCoordinateTransformation

    YMMV. For my GPD WIN as example, I turned the screen 90 degrees clockwise, but eventually I found I need to change the coordinate transformation matrix 90 degrees counterclockwise so the touchscreen would behave properly...

    Once you found a combination that works, may add the xinput command into your display manager's init script, e.g. /usr/share/sddm/scripts/Xsetup if you are using sddm as your display manager.

    4. As said, your mileage may vary. There are too many ways to put the command in - xinitrc, xsession, lightdm (most Ubuntus use it)'s own init scripts, even a xorg.conf.d snippet. It all depends on the distro you are using.

      Good luck and have fun finding the way that works for you... ;)

  18. Hi! Here via the Asus X205TA thread on the Ubuntu forums. Just ran your script to install the kernel and got some error messages, which I've pasted here: http://pastebin.ca/3763786

    dmesg output: http://pastebin.ca/3763794

    Not working: sound, screen brightness function keys
    Working: Bluetooth, WiFi (sort of. It's very spotty, disconnects every few minutes).

    I'm using elementary OS Loki (based on Ubuntu 16.04) on the Asus X205TA. I'll give the ISO a whirl, but would rather just use the kernel. I tried opening the script in nano, but got some kind of encoding error, lots of weird characters.

    Please delete if this is a double post! Like I said, spotty wifi.

    1. You raise an interesting point which I've tried to address in the past however your comment re-highlights the issue: anyone coming to my blog starting from the latest post inevitable means they miss some of the rational, scope and background to my work.

      In summary my blog is intended to be the 'dynamic' update content partner to my 'static' core content pages on my website. This particular post relates to my http://www.linuxium.com.au/how-tos/runningubuntuontheintelcomputestick page where I've created some Ubuntu ISOs whose purpose is to better support Intel Atom based devices.

      Because my ISOs include a patched kernel to address the missing functionality of the official ISOs it means no automatic Ubuntu kernel updates are provided. Consequently I've also developed a manual patching process where a script can be downloaded and then executed to update the kernel to match the official releases. As such my kernel update scripts are not intended to update the kernel installed on other Linux installations. Primarily because you would be missing the 'userland' files required for audio, wifi and bluetooth and the resultant environment may be unstable or worse.

      So returning to your comment, the errors experienced from running the update script are as expected given the circumstances you describe. If you would like to try Ubuntu on your Asus X205TA I recommend you try my pseudo 17.04 Alpha 2 ISO. Perhaps not everything will work however it should be better than the official daily release of the same date.

      Delete
  19. Oh, I see! In my case, long-term kernel updates are probably not going to be an issue, as most stuff works out of the box and the fixes will be included in later kernel versions eventually. I'll try out your ISO.

  21. First I want to thank you for your support in providing us with a ready to install and use Ubuntu tweaked for tablets,
    I have a TreckStor SurfTab Wintron 8.0. I remove windows 8.1 and install your Ubuntu Mate 16.10. Screen + touch, USB, SD are working. Wireless, Bluetooth, Audio, Battery Level Meter, Front and rear webcam not working. I test your Ubuntu 17.04 Alpha 2, version 3, and Wireless (RTL8723BS), Bluetooth (RTL8723BS), Audio (ALC5640), Battery level meter (AXP288) start working, Front and rear webcam also not working.
    As noted for issue is the battery level meter (using AXP288) appear as second battery so preventing standby when level meter is too low, as it also counts the "default battery" witch appear 100%. Second issue is screen on boot is initialized improperly, so it appear nu-synchronized (incorrect horizontal position) most of times, but it can be re-sync by logout or adjust and revert back the display settings. The third and most important issue, the OS is very unstable it crash if you work on settings like display audio, ... so I wait for a Beta version, preferably a Mate one.
    In the end I am happy that things progress step by step, so soon I will have my favorite OS with all hardware supported on my tablet, (I do not care about webcams).
    Thank you,

    1. Just to clarify a little bit my post, I have Ubuntu Mate 16.10 on my tablet from couple of months, testing of 17.04 Alpha 2 version 3 it was done only from USB live image, (without installing), so maybe some or all of this issues are no more existent after installing.

      Delete
    2. I have done another thing, install only the kernel over Ubuntu Mate 16.10, so same issue with display out of horizontal sync on boot (witch prevent me using for log in the on screen keyboard, as touch and display is out of sync), same issue with double the battery, but this time the only improvement is the battery level meter (AXP288), the others remain un-functional (as you mention because of user-land files missing) Also some other same issues like other people, like display rotation and adjusting the back-light (I will test later Version 4)

      Delete
    3. Vesion 4 tested back-light level adjusting also not working for me. I also revert back the kernel to one used on 16.10 otherwise I can't login without keyboard as display out of sync and on screen keyboard can't be used

    4. As you post as a reply on previous comments:

      "From what I can see the loss of wifi with kernels greater than 4.4 is a known issue. I'll put it on the todo list."

      I also check Ubuntu 16.04 and confirm that Wi-Fi is working (so I preferable against Ubunutu 16.10, until the display will be fixed in Mate 17.04 kernel)

      Delete
    5. The system crash issue is related to live image issue on my limited 1Gb system as it creates 500MB swap (on my used 8GB stick) witch is not enough for testing the OS, after install issue is solved.

      Delete
    6. I can also partial confirm that battery level indicator level is valid on the system start, after I have not observed any refresh on it.

    1. So you're saying screen rotation works correctly now?
      Can the T100HA be used as a laptop in landscape mode?

      Delete
    2. Yes, using xrandr you can rotate screen without problems because it boots with nomodeset. Although this only lasts one session, you can make an autostart script that launches and rotates screen every boot.

      Personally I installed Cinnamon GUI and it has built-in display rotation in System Settings and that's persistent so that's how I worked it out but if you want to stay with LXDE then like I said you gotta make that script or mess a little bit with x conf :)

      Delete
    3. I meant it boots without nomodeset, sorry :D

      Delete
    4. that's nice to know... how do you experience the performance of Cinnamon comparing with Windows 10?

      Knowing Cinnamon from my time with Linux Mint it is one of two options I'm thinking about. The second one is Openbox/Tint2 which I also like a lot...

      Delete
    5. Lubuntu with Cinnamon is using like 600MB RAM idling when Windows used at least 1,2GB idling. I think that says it all :P

      It boots a little bit longer (idk how much, 15 secs maybe?) but otherwise works much better and if you open a lot of tabs in web browser (I usually work on 10+) then you should get a tab suspender so it's even faster.

    2. Hello again and thank you for your reply ๐Ÿ™‚
      I've installed it but unfortunately it didn't work. At first I tried it on default LXDE using brightness keys (those are f5-darker and f6-brighter btw), then using settings but I couldn't find a proper setting, only "let power manager handle brightness keys" in power manager, which was checked. Then I tried it on Cinnamon DE as that's what I use everyday but also nothing - neither by the keys nor brightness slider in menu bar on battery icon. Brightness doesn't change.

      Nevertheless, your work made my laptop usable as it's not lagging anymore as on Windows, so I'll be happy to provide more information and tests, just let me know what you need!

      And one more thing - touchscreen rotation also doesn't work. I mean my screen is sideways when booting but I rotated it using xrandr, touchscreen didn't rotate its X and Y axis' so it's unusable.

      If you could take a look at that too, it would be awesome :D! I'm going to sleep now cause it's 0:00, I'll write back in ~10 hours, if you need anything else then let me know :)

    Sound works (but not mic), I've not tested wired headphones
    Wifi works fine.
    Bluetooth works headset audio profile does not work, most likely firmware problem (since it works with generic USB Bluetooth adapter, on the same atom laptops).
    Power management doesn't work but you can see battery charge level but updates is only done at boot time.
    I've tested a lot of video etc and no issues with hanging as per before.

    I'm trying to focus on getting headset Bluetooth sound to work and I found you on github but it looks like u been doing updates after and not updated github.

    I was looking for the BT driver but can't see it loaded or am I wrong looks like you complied in the kernel it self or did you rename? Wanted to test different firmware to see if I can get things working better.

    1. Did you go in and choose the different cards in the sound settings, I found it no sound at startup but when switching "card" in the sound setting it worked. (This is tested on the Ubuntu 17.04 pseudo Alpha 2 (Version 4) ISO)

      Cheers Jorm

  52. First and foremost, thank you for this very useful work.

    I have tested (3/4 successfully) your Ubuntu Unity 17.04 on an Asus T102HA mini-notebook.

    My review is too large to be accepted in this blog, which won't accept two posts from the same person.

    This review can be read on https://drive.google.com/file/d/0B1gfn4_V_wm3Y2xHd242Z0RXTmc/view?usp=sharing.

    Hope this helps,

    1. Hi just read your review on google drive you can fix the touch rotation if you google "InputCoordinateTransformation Ubuntu" there is a very helpful wiki on how to rotate/flip the touch. after a lot of google time i also made a script to change this on startup after install. hope this comes i useful

      Delete
    2. #!/bin/bash

      #xinput set-prop 'NAME OF TOUCH SCREEN' 'Coordinate Transformation Matrix' MATRIX REQUIRED TO CHANGE TOUCH ROTATION


      xinput set-prop 'Goodix Capacitive TouchScreen' 'Coordinate Transformation Matrix' 0 1 0 -1 0 1 0 0 1

      this is the contents of the script i used to set you on the way whilst you are testing this you can use the terminal to apply the different matrices to try them before setting the script up hope this helps

      ps save the file with a .sh extension and then use terminal to chmod 755 file then you can add that file to "startup applications" search for it when you click the ubuntu logo top left

  53. It's under sound control, there will be two output for the sound card, and one for head phone and one input for mic. If I get the time in the next day or too I will try to fix a screenshot.

    Cheers Jorm

    1. Hi Jorm, please send the screenshot, just because in case I'm wrong. I onlo have one sound card in the options, but in the comand line and in alsamixer, I have 2.
      Thanks a lot for your help!

      Don't know if link will work well but as u can see there is two outputs (not really card and its' first when pressing this output when i get sound to work). This might have to do with the fact that Linuxium been focusing on HDMI sound which is important for him and laptop users simply need to switch by clicking. Anyways it works for me in stereo mode.

      Delete
    3. So my problem is bigger that I though... I don't have so much options there, I only see one card... :(
      What can I do to see all that?
      Thanks!

    1. Neither of the ISOs above are 'yakkety' based so perhaps you need to re-download and write to your USB again.

  56. Hello,

    many thanks a lot for your great work!
    I'm sorry for my bad english writing:(

    I have a new Cherry Trail EzPad 6 with keyboard dock. With your 16.10 image there are freezes. I got it ran with your latest 17.04 image and a bit investigation.

    work:
    - wlan with brcmfmac driver / sometimes i have to modprobe -r followed by modprobe
    - basic touchscreen mssl1680 function. I have extracted the firmware/ copied to /lib/firmware and then installed the driver from https://github.com/onitake/gslx680-acpi

    don't work:
    - sound = es8316 chip
    - bluetooth

    problems:
    The tochscreen curser is out of my finger tip.
    If i calibrate it per xinpunt_calibration it has no effect.

    If i do
    xinput_calibrator --output-type hal
    and do the changes in /etc/hal/fdi/policy/touchscreen.fdi
    it has no effect.

    Even if i create a 99-calibration.conf with the parameters from xinpunt_calibration in etc/X11/xorg.xconf.d/ or /usr/share/X11/xorg.conf.d/
    gives back following error:
    http://pastebin.com/9fv94Fzu

    sudo xinput set-int-prop "11" "Evdev Axis Calibration" 32 208 6704 -9163 651 don't give an error but have no effect.

    If i do something like
    xinput set-prop "11" --type=float "Coordinate Transformation Matrix" 1.345 0 0 0.7 1 0 0.5 0 1.2
    the touchscreen curser position relative to my fingertip change but i have no how i can figure out the right parameters.

    here is a link to the extracted and working firmware of the touchscreen
    https://drive.google.com/file/d/0BxdE_cqOAhqQSlQ5ZlliVEF4Qms/view

    I wonder why the xinpunt_calibration don't work?

    Wlan:
    If i do a dist-upgrade and it touches the kernel then i run the
    linuxium-install-zesty-kernel-4.10.0-5-linuxium.sh script.
    After a reboot Wlan don't work. If i copy the baked up /lib/firmware folder from the fresh install over the updated folder i regot it to work.

  57. Running xubuntu 16.04 with 4.9.0-11-linuxium since 33 days on a meego pad t02:

    - sounds is working, hdmi and jack with the UCM files (sound seems better on hdmi), but after a few days I began to get a lot of messages in syslog

    Feb 19 07:29:49 meegopadt02 kernel: [2794326.723013] hdmi-lpe-audio hdmi-lpe-audio: invalid position: , pos = 4416, buffer size = 4416, period size = 1104
    Feb 19 07:30:33 meegopadt02 kernel: [2794370.273062] had: Driver detected 1 missed buffer done interrupt(s)!!!!

    but it doesn't seem to affect the fonctionnality.

    - bluetooth is working, but when disabled via applet or rfkill, I need to relaunch it with :

    sudo rtk_hciattach -n -s 115200 /dev/ttyS4 rtk_h5

    - wifi was working great when I was near the access point, now that I'm farther it's not very good. First the signal is very dependant of the position of the meegopad, obviously related to the antenna. It's sometimes kinda stuck, running

    sudo iw wlan scan

    improves things like if a buffer needed to be purged.
    Still there is a lot of packets dropped :

    wlan0 Link encap:Ethernet HWaddr 58:63:56:bd:06:33
    inet addr:192.168.1.18 Bcast:192.168.1.255 Mask:255.255.255.0
    inet6 addr: fe80::4ebd:ede9:39c7:e459/64 Scope:Link
    UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
    RX packets:59428 errors:0 dropped:60575 overruns:0 frame:0

    - sd card : it's working but iirc there was still some complaints appearing in syslog, but I don't use it a lot.

    I've installed thermald because there is no fan, it's working ok with the default configuration.

    I've activated turboboost:

    for X in $(cat /proc/cpuinfo | grep processor | cut -f2 -d':'); do sudo wrmsr -p$X 0x1a0 0x850089 ; done;

    which gives a 20-25% performance boost.

    After upgrading the graphics stack with the paulo-miguel-dias's ppa I had to add a configuration file in xorg.conf.d to have tear free videos, even with TearFree the graphics is performing a lot better versus the graphic stack available in vanilla 16.04.

    mpv with vaapi (and TearFree option) is the less intense option for the cpu to use the meegopadt02 for video.

    Before xubuntu I tried the 'vendor' ubuntu 13.10 and the performance was very bad, compiz was constently using the cpu which lead to temperature 70°c, perhaps it's better with a newer ubuntu.

    No sleeping modes are working, even freeze mode fails to wake up, I'm not sure if it's linked to the pm mode of the wifi driver or simply a limitation of the rtc.

    I've also tested opengl, after 2-3 minutes the performance is divided by 3-4 after the temperature rises to a threshold, but this is expected for a device without a fan.

    Thank you.
    A lot.

  59. I've been trying the 16.04 and 16.10 Xubuntu builds on my X5 Z8300 tablet and getting stuck on a black screen during boot. I'll try the newest when I get home this evening. Any plans of making a Xubuntu release for 17.04?

  60. hi,

    have get my hands on a Lenovo Miix 3-1030
    at first great work!

    working:

    - touchscreen
    - keyboard
    - touchpad
    - soundkey and powerkey

    not working:

    - wifi
    - bluetooth
    - sdcard
    - sound
    - backlight

    Technical data:
    CPU: Z3735F
    RAM: 2GB
    WiFi: Realtek RTL8723BS Wireless LAN 802.11n SDIO Network Adapter
    Sound: Intel SST Audio Device (WDM)

    dmesg:
    http://pastebin.com/gunzgtCm

    the sdcard / mmc0 problem may has todo with:
    [ 2.906061] genirq: Flags mismatch irq 8. 00000088 (mmc0) vs. 00000080 (rtc0)
    [ 2.909958] mmc0: Failed to request IRQ 8: -16

    not sure if it helps IRQ list from windows:

    Subject: [PATCH] x86/platform, acpi: Statically assign IRQ numbers in ACPI
    hardware reduced mode

    We should be able to dynamically assign IRQ number on the platform in ACPI
    Hardware-reduced mode, but on the Bay Trail-T(ASUS-T100) platform, there is
    a RTC device still using the legacy hardcoded IRQ8, which could cause the
    following error:

    7486341a98f: genirq: Flags mismatch irq 8. 00000080 (mmc0) vs. 00000000 (rtc0)

    So we want to statically assign IRQ numbers in ACPI hardware reduced mode to
    fix this error

    1. The commit you shared, has it already been merged into the kernel ?
      I'm interested as I own an T100TA and I'm trying to figure out what kernel version should I opt for that has fewer issues (less patching better life). I'm new to this stuff so I rely only on other's hard work to install an over-all stable linux build.
