Public bug reported:
While this machine is capable of much more I have not been able to get
the video resolution to operate at greater than 1280x800 (16:10). 2D and
3D capabilities do not exist. (basically the video sucks).
I know that the pci-ids for the video are 2a42 and 2a43 but it does not
appear to be picking it up and only uses the generic VGA driver. I have
kept up with the latest kernel updates and did switch over to the PAE
version (I know, 32 bits... it is what I had on the rescue disk at the
time)
Some of the fixes appear to involve changes to the backlight levels.
Right now the machine comes up and [function] up/down arrows work fine
for screen backlight control. Can this "bug" (undocumented feature) make
it onto the list for a fix to properly detect the on-board video and
resolution capabilities? I wish this machine had an NVIDIA but wishing
is not going to put real video on this machine.
