I am trying to configure an old laptop, and this is driving me up the wall. I have spent at least ten hours trying solutions to no avail.

I initally installed mesa 7.11, which did not work. I currently have mesa 8 along with the Xorg Edgers mesa-legacy 7.11 drivers.

sudo lshw -c video returns:

display UNCLAIMED     
       description: VGA compatible controller

My current xorg.conf looks like this:

Section "Screen"
    Identifier "Default Screen"
    Device     "Card0"
    Monitor    "Monitor Generic"
    SubSection "Display"
    Depth 32

I have tried many different Xorg options, downgrades of driver packages and the like. The only two outcomes I have been able to achieve are:

NoAccel in xorg.conf: VGA driver is used, and GLXgears gets ~5 FPS. Not an optimal outcome.

Anything else: Any OpenGL application crashes on startup with the error "Wait returned -16" and the system completely locks up, necessitating power cycling.

Well, there is a third outcome that I noticed: enabling ShadowFB caused artifacts all over the screen and made the bottom half of the screen unusable.

Any help is much appreciated. I have seen that this issue has been raised before on several websites while trying to diagnose this problem, but nothing suggested has worked.

I managed to fix it...Kind of. It still says display unclaimed and GLXinfo crashes, but I can run OpenGL applications.

I added this to Xorg.conf

Section "Device"
    Identifier  "Card0"
    Driver      "savage"    
    Option      "AGPMode"   "4"
    Option      "HWCursor"  "True"
    Option      "UseBIOS"   "False"
    Option      "ShadowStatus"  "False"
    Option      "AGPSize" "16"
    Option      "DmaMode" "Any"
    Option      "DmaType" "AGP" 
    Option      "BusType" "AGP" 
    Option      "ForceInit" "Yes" 
    VideoRam    32768 

Section "dri"
    Mode         0666

I also messed around with settings in DRIconf. I still don't understand what the problem was as the savage driver was being loaded correctly, DRI rendering was active, and I could find no errors in any logs.
