    Exclamation Video card not detected - 9.10, 9.04, 8.04

    Working on a friend's PC, which was previously running XP and got a very nasty virus infection. I convinced him to try Ubuntu, showed him the interface running on my own machine and he was hooked. Backed up all his data to network, completely erased the hard disk and install Ubuntu. Sounds easy, right?

    Installed 9.10, it didn't detect the video card and xorg.conf was missing from /etc/X11. After some messing around trying to get it to work, I realised that the
    sudo dpkg-reconfigure -phigh xserver-xorg command wasn't working properly and didn't produce the menu shown in the screenshots. After some digging I found that this was a bug in 9.10, so to make the job easier, I wiped the drive again and started again on 9.04.

    With 9.04, at least the xorg.conf file was there, but had no entries under configured video device. I tried adding "vesa", "via", "openchrome" (all on separate attempts), all to no avail. I retried the dpkg -reconfigure command above. still no menu.

    Now several days into this "easy" install, I rolled back to the LTS release (8.04 - hardy) and installed that instead. Still no video card detection, and resolution is obstinately stuck at 800x600. Tried the same string of tests again, and now admitting defeat and asking for help!!!

    The relevant output from lspci is:
    01:00.0 VGA compatible controller: VIA Technologies, Inc. VT8378 [S3 UniChrome] Integrated Video (rev 01)

    The output from xrandr is:
    Screen 0: minimum 640 x 480, current 800 x 600, maximum 800 x 600
    default connected 800x600+0+0 0mm x 0mm
    800x600 60.0* 56.0
    640x480 60.0

    The sections from xorg.conf are currently:
    Section "Device"
    Identifier "Configured Video Device"
    EndSection

    Section "Monitor"
    Identifier "Configured Monitor"
    EndSection

    Section "Screen"
    Identifier "Default Screen"
    Monitor "Configured Monitor"
    Device "Configured Video Device"
    EndSection

    Section "ServerLayout"
    Identifier "Default Layout"
    Screen "Default Screen"
    EndSection

    Any suggestions would be much appreciated!

    Re: Video card not detected

    That xorg.conf is naked, it is missing SEVERAL vital lines.

    If you could do two things for me, pastebin the /var/log/Xorg.0.log

    and try this

    Code:
    sudo X -configure
    sudo mv /etc/X11/xorg.conf /etc/X11/xorg.bak
    sudo cp ~/xorg.conf.net /etc/X11/xorg.conf
    startx
    if that doesnt work pastebin that Xorg log as well.

    cheers.

    Re: Video card not detected

    I copied the logfile to desktop and attached it - changed it to .doc for the uploader.

    I'm running in X at the moment to post this, so the commands failed:
    sudo X -configure
    X already running

    sudo mv /etc/X11/xorg.conf /etc/X11/xorg.bak
    done

    sudo cp ~/xorg.conf.net /etc/X11/xorg.conf
    file does not exist

    Rebooted and dropped into terminal; Ran the sudo X -configure from there. This produced a new file /root/xorg.conf.new .....

    On running a test server with this file, it produced a grey staticy screen (think a tv with no signal, but not moving) and the mouse pointer became a black X with white tips. It didn't progress from there and I had to kill it to get out of it.

    Here is the logfile from the test server run ....

    (had to figure out which log it was!)

    Still using the .doc extension as the .txt extension is limited to 19kb

    Re: Video card not detected

    I didn't see any replies, so I've been "playing" with it a bit, pulling bits and pieces from different posts. I've managed to get it to 1024x768 using the following xorg.conf :-
    Code:
    Section "InputDevice"
        Identifier    "Generic Keyboard"
        Driver        "kbd"
        Option        "XkbRules"    "xorg"
        Option        "XkbModel"    "pc105"
        Option        "XkbLayout"    "us"
    EndSection
    
    Section "InputDevice"
        Identifier    "Configured Mouse"
        Driver        "mouse"
        Option        "CorePointer"
    EndSection
    
    Section "Device"
        Identifier    "Configured Video Device"
            Driver          "via"
    EndSection
    
    Section "Monitor"
        Identifier    "Configured Monitor"
        Option        "DPMS"
        HorizSync    28-64
        VertRefresh    43-60
    EndSection
    
    Section "Screen"
        Identifier    "Default Screen"
        Monitor        "Configured Monitor"
        Device        "Configured Video Device"
        DefaultDepth    24
        SubSection "Display"
            Modes        "1024x768"
        EndSubSection
    EndSection
    
    Section "ServerLayout"
        Identifier    "Default Layout"
        Screen        "Default Screen"
    EndSection
    Please don't ask me why or how, but it works!

    How can I add back the lower resolutions to make them optional while keeping the 1024x768 as the default?
