Ubuntu 13.04 raring to go on Acer C7 Chromebook

unity automated tests raring1

With Ubuntu’s new release out this week, i wanted to share with you how to get this working in a chroot environment alongside ChromeOS on the Acer C7. I have covered how to put the C7 into Developer mode in a previous post so won’t outline it here. Head over to for instructions on how to get that part done.

Once you have completed Step 3 head back over here

CROUTON Command Line

Most of the guides you will see using this utility mine included cover how to get Ubuntu 12.04 the LTS version working, however there is also scope within the command line to get the latest and greatest up and running.  specifically the -r switch. Issuing the following command will provide you with a bare bones Ubuntu 13.04 install

sudo sh -e ~/Downloads/crouton -t unity -r raring

this will start the install process wihc on an 8meg link will take about 15 to 20 minutes

Starting Unity

The installer suggests a whole load of stuff about starting a chroot shell, ignore it..


sudo startunity

obliviously if you chose kde you would type

sudo startkde

The Ubuntu GUI will start

Swapping between ChromeOS and Ubuntu

Pressing ALT CTRL and F1 (back) while in ubuntu will take you back to ChromeOS

Pressing ALT CTRL and F3 (reload) while in ChromeOS will take you to Ubuntu

Post Install

As mentioned this is the bare minimum Ubuntu 13.04 install, and it does the job however it is possible to get it a bit closer to what you might find on the CD install on a normal PC to do this you will need to drop to XTerm as gnome Terminal isn’t installed.

Type in:

sudo apt-get update
sudo apt-get install gnome-terminal

sudo apt-get install ubuntu-desktop ubuntu-restricted-extras nmap ssh

the last two are not essential, i just make use of them

sudo apt-get install unity-tweak-tool
sudo apt-get install gnome-tweak-tool
sudo apt-get install synaptic
sudo apt-get install compizconfig-settings-manager compiz-plugins-extra
sudo apt-get install p7zip-rar p7zip-full unace unrar zip unzip sharutils rar uudeview mpack arj cabextract file-roller
sudo apt-get install gstreamer0.10-plugins-ugly gstreamer0.10-ffmpeg libxine1-ffmpeg gxine mencoder libdvdread4 totem-mozilla icedax tagtool easytag id3tool lame nautilus-script-audio-convert libmad0 mpg321

Some additional tweaks

Show username on panel:
UserName is disabled by default in Ubuntu, So here is tweak you can enable it very easily.

Enter following command in terminal:

  • gsettings set com.canonical.indicator.session show-real-name-on-panel true
To remove name from panel, Enter following command:
  • gsettings set com.canonical.indicator.session show-real-name-on-panel false

Disable overlay Scrollbars:
You can disable overlay scrollbars, if you don’t like that.

Enter following command in terminal to disable overlay scrollbar:

  • gsettings set com.canonical.desktop.interface scrollbar-mode normal

If you want to get back overlay bar, enter following command:

  • gsettings reset com.canonical.desktop.interface scrollbar-mode

      Are you upgrading the ram? Or changing the hard drive to ssd? If either one can you tell us how the device works after? How muh of an improvement, stuff like that. Thanks.

        I did update the ram to 16gbon chrome os it does make a difference if you use LOTS of tabs as I do, Ubuntu using whatever means is much snappier too..

    I’m a bit new to the whole Chromebook and Linux scenes, but I was curious if this would work on a Samsung Series 3 Chromebook as well?

    • projectzme

      I got the original idea from a Samsung chrome book site, I believe this will indeed work.

  7. I’m having a problem logging back into linux after rebooting for the first time. After turning it back on, waiting for it to log in with the developer mode, then open crosh and type in “sudo startxfce4” is says it replies with “unknown command: ‘sudo'”. Any ideas why it won’t let me use the sudo command? I am using a samsung chromebook, but I would imagine the process is the same.

    Thank you for this great tips. I found lots of useful information in your blog.

    One thing that I wanted to ask you relates to the error I’m currently seeing with Unity running in Crouton. It seems that I cannot install any of the apps from Ubuntu Software Center. Every time I try it just shows an error “Authentication service is not available”. Did you have such error on your side? How can it be fixed?

    Thanks in advance!

    • projectzme

      I never use the software centre, even on normal installs, however if you know the command line for launching it (which is probably ubuntu-software-centre ) then open a command line and type in

      sudo ubuntu-software-centre

      (If its not ubuntu-software-centre then google might help)

      I personally use either apt-get to install software or synaptic

      The reason it’s failing for you seems to be anything which would normal require raised privileges and invokes gksudo doesn’t work. Maybe try from the command line

      sudo apt-get install gksudo

      Then try software centre

      There are differences between sudo and gksudo, I have seen when bash scripting in the past..

    Thanks again. I managed to fix that by running next command:


    It launched the authentication service that was not running and now Software Center allows me to install apps.

    I also tried to add that command to a Startup Apps in order not to run it after each boot, but unfortunately it didn’t work. Probably I’m doing something wrong (as I mentioned I’m new to linux).

    Anyway I hope this might be helpful to anyone.

      That did not work for me:

      (polkit-gnome-authentication-agent-1:9862): polkit-gnome-1-WARNING **: Unable to determine the session we are in: GDBus.Error:org.freedesktop.ConsoleKit.Manager.GeneralError: Unable to lookup session information for process ‘9862’

      Any suggestion ?

      Also is it safe to try saucy salamander yet ?

    Hello, I have a question: I tried to instal ChrUbuntu first, and in the process I managed to ruin my hard disk partitions. Now I have the 250Gb I left for ChrUbuntu unused, and just 70Gb usable on ChromeOS.
    If I install crouton, can I use gparted to restore the hard disk to a factory state? If not, can I remove the hard disk and format externally on another pc?
    If that’s imposible, is there a way to reformat the disk to a factory state in developer mode?

    Thanks in advance!

    A couple things, I followed everything above, but I can’t get my time to show up in the top bar. It just displays “Time.” When i try to change the date and time settings, I can’t adjust anything except am/pm or 24hour clock. Also, I cant find the Unity Tweak Tool. I search for it, and it doesnt come up in the launcher, but if i search for it in the software center it shows it’s already installed.

      Wow.. Your going to maybe have to google that..
      The install is very basic, check you have all the repositories ?

      Sorry that’s going to take some thought..

        Hi there, Great instructions thanks, it’s got me a long way in already.

        Am having the same issue as dface603 in Unity. Unity initialises fine but all the settings are read-only. Accessing the User Settings I can see my Admin account is also locked – the unlock button gives tool tip saying ‘System Policy Prevents Changes’. Bit of a grey area for me!

      • projectzme
        July 3, 2013

        I don’t get that problem.. I wonder if anyone else can help..

        I wonder if its because its trying to use gksu to unlock the admin settings

      Run “sudo dpkg-reconfigure tzdata” to fix the time display.

    Any tips on changing wireless networks on the fly? nm-app isn’t in top panel and get error message when opening gnome control center -> Network = ‘The system network services are not compatible with this version’

    • IanM
      July 5, 2013

      Found the answer on Crouon dev: Chromium OS has full control of networking, so it’s not a good idea to try to control it from the chroot.

        Thanks for letting us know.. I’m going to go through the comments on this blog post and update a tips/questions section soon.

    I installed the Raring and after rebooting, I started crosh and typed in shell (like I did with Unity on my Acer C7-Im upgrading from the 12.04 that I had) then typed in sudo startunity and it comes up with I must sign in with enter-chroot. After doing that it says the file is currupt and wont mount raring. I tried to update it but that did nothing. It wont start up under shell sudo startunty. How do I delete it? or What can i do? Can you give me some info so I can boot back into Unity?

    • projectzme
      July 21, 2013

      I’d suggest deleting the chroot environment, and starting again.. I believe the blog post covers that near the end.

        Is there anyway i can stop the hard drive from erasing itself when i boot back into normal mode??? My dad accidently booted into normal and it erased everything i had. my minecraft saves too sadly. thanks

        Fraid not, its a cload based PC essentially.. being able to put Ubuntu on there is just a perk.

    I just picked a c710 off ebay. According to it will only go up to 4gb of ram. Can you confirm you can add (2) 8GB sticks to get 16gb?

    • projectzme
      August 17, 2013

      I’m going to be a bit careful here, because PC vendors have a habit of changing spec’s I have 16Gb (2×8) in my Acer C7, the OS doesn’t technically support more than 4Gb being a 32bit OS HOWEVER its a PAE kernel which essentially means every tab you open does so in its own memory space so you can utilise over 4Gb.

      chrome://system and then Expand memory_spd_info you can get some more information on what speeds your Acer supports

      Then have a read of

      Hope that helps?
