    Question "Your system is running in low-graphics mode'' after Ubuntu 12.04 LTS update

    Hello!
    I own a Acer Aspire 5552 laptop, which has Ubuntu on it. And now i updated it to 12.04 LTS from 11.10. When i turn the laptop on, it says : Your system is running in low-graphics mode, Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself.
    I read about this on Ask Ubuntu already, and it suggested to got to Ctrl + Alt + F1 and reinstall my desktop, or install fglrx. Well, these things what I read on this site : http://askubuntu.com/questions/12545...0-graphics-car

    Both of them don't work. And if I don't enter Terminal and just click OK (press Enter, because the mouse cursor isn't there) when it says you system is running in low-..., I get options, but i can't choose any of them, can't even click cancel or OK. My graphics card is ATI Mobility Radeon HD 4250. Help please! Thanks

    Try booting into 'Recovery Mode' from your GRUB Menu, there is a menu in there which includes 'failsafeX - Run in failsafe graphic mode', or something like that depending on what exact version of Ubuntu you have. That will lead you to more menus and you can reset your graphics (get rid of your specific graphics card driver temporarily), and continue with a normal boot.
    After that you can install a graphics card driver again or not, it's up to you.

    Actually, in Precise Pangolin beta, my mouse and keyboard don't work in the text console either, to select 'Reconfigure Graphics', or 'OK', so I'm stuck too as I'm testing my own solution in reply to your question. I hope that's fixed in the final release, which I have downloaded but not had time to install yet.

    Another way to do the same thing is to mount your operating system in another Ubuntu such as a Live CD and delete or (better idea) rename the /etc/X11/xorg.conf as a backup of the same file.
    Then perform a normal boot and if you want, re-install a graphics driver.

    The 'failsafeX - Run in failsafe graphic mode' didn't work, it still takes me to the same error place, and it doesn't give me any more menus.
    Give me something else to try, please

    Have you already done

    Code:
    sudo apt-get install fglrx
    in recovery mode?

    What sort of graphics card have you got?
    PC

    To get a terminal command to put its output into a file use this format
    {terminal command} > {filename}

    I had the exact same problem and solved it by:

    On my one pc i had to do a clean 11.10 install and before installing any other software do the upgrade.

    I did it, and this is what i got:
    Code:
    W: Not using locking for read only file /var/lib/dpkg/lock
    E: Unable to write to /var/cache/apt/
    E: The package lists or status file could not be parsed or opened.
    I have a Ati Mobility Radeon HD 4250.

    Edit:
    Now i tried the same thing when i just started the laptop, got the error and used Ctlr+Alt+F1 to go to the terminal, and entered the code there.
    It loaded and stuff, downloaded and so on. But i can't really say what it says, because my laptop language is Estonian, not English, so you won't understand all of it.

    But i'll try to transalte the end of it:
    The following files(or packs) made errors:
    Code:
    /var/cache/apt/archives/fglrx_2%3a8.960-0ubuntu1_amd64.deb
    E: Sub-process /usr/bin/dpkg returned an error code (1)
    So that's it...help

    Try doing

    Code:
    sudo apt-get purge fglrx
    (I think thats the correct command).
    This will get rid of any old fglrx files that might be interfering.

    Once thats been done, install it again.

    Then reboot.

    To get a terminal command to put its output into a file use this format
    {terminal command} > {filename}

    Okay, i tried it.
    At first it says :
    Code:
    Reading package lists... Done
    Building dependency tree
    Reading state information... Done
    And then comes Estonian language lines.
    But if translated, it looks something like this:
    Packet fglrx was not removed, because it has not been installed.

    Then there is an english line:
    You might want to run 'apt-get -f install' to correct these.

    and some other stuff.

    So yeah, that failed
