First look at Ubuntu 18.10 (Cosmic Cuttlefish) with Communitheme

Ubuntu 18.10 will be known as Cosmic Cuttlefish and daily builds are available for testing. It is expected that when Ubuntu 18.10 is officially released on October 18th it will include the community-created 'Communitheme' as the default desktop theme. I've respun a daily build ISO using my '' script and included the latest development version of 'Communitheme' together with the latest mainline kernel v4.17.

I've created three ISOs suitable for standard Intel, Intel Atom and Intel Apollo Lake devices:

  • standard
  • Atom
  • Apollo

The basic respin command is: -i cosmic-desktop-amd64.iso --command "echo 'deb bionic main' > /etc/apt/sources.list.d/communitheme-ubuntu-ppa-bionic.list; DEBIAN_FRONTEND=noninteractive apt-key adv --keyserver --recv-keys DEE9D5E11727231736FD173F03D12CDECFB24D48; apt update; DEBIAN_FRONTEND=noninteractive apt install -y ubuntu-communitheme-session" --kernel v4.17 

with the additional options of '--boot grub-64', '--atom' and '--apollo' for each device type respectively.

To access the 'Communitheme' from a LiveUSB you will first have to open a terminal window and set a password for the default user (enter 'sudo passwd ubuntu' followed by your chosen password) and then log out (click the 'power' icon top right and select the 'Live session user') and finally log back in having first selected the theme (by clicking on the 'gear' icon next to the green 'sign in' button).

Update: ISOs have been removed due to lack of space on hosting service.

Please donate if you find the ISOs or script useful using the following link


  1. I have an Alfawise X5 mini pc. This is the dmesg . Can you help me fix the headphone jack audio. I have the HDMI audio working using the instructions from your site. Thanks.

    1. There are so many BIOS errors that I'd be tempted to look for a later BIOS upgrade although that in itself is risky. Otherwise try either respinning with an 'RC' kernel or progressively downgrade the kernel and see if that resolves the BIOS issues to the point you can actually see what is wrong.

  2. Установил систему под Atom - нет звука, если быть точным, то на экране входа звук работает, после входа - он исчезает. Если выйти из системы звук снова появляется. Не подскажите как это исправить?

    1. Have you tried ''?

  3. Is this ISO working for Z83-4 (headphone, wifi) ?

  4. I tried using your Atom ISO for this device: (Powered by Intel® Atom Z3735G processor) but I only get blackness on boot and it just stays like that. Secureboot is off and I’ve tried your other ISOs as well (16.04) and none of them have worked for me.

    1. Try adding 'nomodeset' to the grub parameters before booting (use 'e' to edit and 'F10' to boot) or try respinning the ISO with an additional '-u' option to get the very latest kernel to see if this helps.

    2. I’ve tried this and I can get another installer to boot, but only in portrait mode (sideways) but cannot get the screen to rotate to landscape mode with xrandr. Also I’ve tried the latest kernel and cannot get it to boot at all even with “nomodeset”. The sideways install with nomodeset in kernel 4.15 doesn’t have working touchscreen, bluetooth, webcam, or sound; trackpad, keyboard and WiFi work, but it’s all awkward and unusable being the screen is sideways and locked out of rotation due to the nomodeset flag.

    1. This should be fixed with the latest version (i.e. 8.2.4).

  6. Hi!

    My tablet use the file rtl8723BS_nic.bin for wireless driver. In "dmesg" it showed that the system couldn't find the file in the folder /lib/firmware/rtlwifi/

    I simply coppied and renamed the rtl8723eu_nic.bin to rtl8723bs_nic.bin in the folder, rebooted and the wireless started to work.

    I hope this could help somebody!

    Thankx linuxium, awesome work. I'm having alot of fun with my tablet (CCE TF74W)

    1. Or if you use the 'atom' ISO above it automatically includes 'rtl8723bs_nic.bin' in '/lib/firmware/rtlwifi/'.

  7. trying to work out if i can install Ubuntu (or similar) on my linx12x64. the closest i could find to it is someone on a site called reddit who says he installed "mint" on his but the wifi wouldnt work (big issue for me) and a follow up post linked to your blog.... so will the atom version of this work on my linx12x64 and what are the steps to achieve that (download the iso and use rufus? or something more complicated?)

    Thanks in advance as I am completley stumped lol just want to get better performance from my tablet than windows 10 will provide.

    1. See my April posts for information on installation and ISOs are available from - probably best to start with the 'Atom' one if stumped.

    2. I tried the atom iso on linuxminipcs and your atom iso linked in the article, both hit some issues when ran as a live disc:

      Critical issue:
      every 30 seconds or there abouts the screen would go dead for 10 to 20 seconds. This happened even when the loading diagnostic text is showing during boot.
      At first I believed it to be the screen timing out but I did a test, I loaded terminal and started typing 1 2 3 4 and so on, I got to 25 and the screen cut out. I carried on typing, the screen came back at about 41 now the text in the terminal showed ....24 25 2 40 41 (this was without the spaces, added those to make it easier to see what I mean) so at 26 the system hung until I got to 40 and then resumed.
      (could this be the result of using a usb2.0 flash drive as a live cd on a tablet? would installing it fix this issue? bit loathed to try on a hunch but not really familier with live discs so if its a know issue I will try it.

      High impact issues:
      when loading the screen was in landscape mode (tablet with keyboard is essentially a laptop so that is perfect) once the desktop had loaded it was in portrait mode and refused to rotate itself. Funny enough the touch pad on the keyboard actually worked as though I was holding it portrait too (right was up etc)
      I went to settings then display to rotate it but it said no displays were regonised. I tried xrandr -o right in terminal but nothing happened.

      The wifi adapter was not detected (it is a Broadcom 802.11ac WDI SDIO adapter according to windows device manager) missing driver or not supported by linux?

      low but annoying issues:
      despite the hedphones being plugged in sound insisted on coming out of the speakers (not good at work lol)

      Are these fixable issues? did I just do something dumb? or is it a case of linux simply will not work on my system?

      The tablet is a linx 12x64 (intel(R) Atom(TM) x5-Z8350 cpu@1.44ghz if that helps

    3. I tried Mint 19 (xfce) this loaded and worked great, no wifi and no sound but no screen cutting out with system hang every few minute.

      I fixed the wifi issue using this
      (I used bluetooth tether to my phone to download the file REALLY slowly lol)

      but that sound issue....ah man...I have tried so many things (even one that updated the kernal to 4.18 that killed video playback on youtube and still did not fix the sound) eventually the sound drivers just gave up and it switched to "dummy device" (up until that it was listed as intel . something something e8000 something....its been a long day and night with little sleep)

      I am about to try lubuntu, tbh I am starting to think Linux is not meant for casual users, I really want to speed up my windows tablet but I just do not feel Linux is there yet in terms of driver support.

    4. Lubuntu worked for video again (no system hangs or freezes) but again no sound
      in the volume control it comes out as atom/celeron/pentium processor x5-e80.... (I am sure on another version of linux it showed e8000) when i run a speaker test (speaker-test in terminal) I can see the bar moving as though there should be sound but hear nothing through the speakers or headphones

      about to try an older version of ubuntu (16) then giving up as i need the tablet in 2 and a half hours and i really should of had more sleep before work lol (sorry for multiple replies, hoping that you may look at this and go "aha its that, heres the fix" and because it may be useful to note that the new ubuntu does not work on the linx 12x64

    5. the older version of ubuntu had the same issue no sound, no wifi and the annoying freezes.
      went to return to windows but the recovery system on the tablet has been overridden by one of the linux versions...doh, fixable i believe though from what I read it will of forgotten its license and i may need to purchase one.
      Costly endeavor trying to put linux on a windows tablet both in time and money, really do not recommend this to anyone

    6. Try respinning the latest Ubuntu ISO with the command (and downloaded links) in

      To fix your Broadcom wifi follow the recommendations under Wifi issues in

      Once you have booted post a dmesg using pastebinit or similar so I can look at the audio issue.

  8. Thank you, would of thanked sooner but only just seen the reply lol
    will look at april and the site :)
