    It seems that the Gaphic driver of ubuntu12.04 has some problems on my board(UDOO Dual). The "Gaphic driver"opinion in the "system information" is blank, and the OpenGL seems not work. I can't paly video with media player as well. Anyone could help? Thanks.(I had ask one of my friends who has Qual, but his doesn't have the problem.)

    Hi,

    Maybe you have installed some application with apt-get.

    Launch this command:

    udoo#/opt/gpulink-x11.sh
    udoo#reboot

    And then try again!

    Ok,

    If you want to check that opengl works you have to launch this command, open a terminal and then:
    $glxgears

    Post the result of this command:

    $glxinfo | grep -i direct

    Hi,

    Thank you very much for reply. I just try the command

    $glxinfo | grep -i direct

    the result is

    Error: couldn't find RGB GLX visual or fbconfig

    I preformed that command through MS Remote Desktop on my laptop.

    I searched the result and it seems to be problems with GPU driver, but I didn't find an effective way to solve that. What should I do? ( I did have reinstalled the system before, but dose not work. ) Looking forward to effective method. Thanks a lot!

    Try running
    Code:
    sudo usermod -a -G video <username>
    then rebooting.

    Hi,
    Thanks for your reply. I tried but it still not work. It seems that no Qual has this problem, maybe it's a bug to Dual? Maybe I should wait for Debian :roll:

    Did you replace <username> with the username you use to log in to Ubuntu? I only have a quad so I can't test this myself.
    I did use the Debian armhf image from the download section a few days ago and I think opengl was working better than ubuntu out of the box.

    Yeah, I replace <username> with ubuntu, as I have never changed it. The command did not make any error, but the problem is still there. As I'm new to linux, I'm still waiting for a stable version of Debian. Thank you again! :D

    Hi,

    You have to launch the command I said before in a graphical terminal inside desktop.

    If you launch in a remote shell it will give an error because the procedure is quite different.
