Description of problem:
Only working mode is 640X480 (HP OmniBook XT6050).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1) Run a Xconfigurator to set display and resolution (set resolution to 1024X768);
2) Let it start X test;
Actual Results: It will give You an error about X configuration.
To get X working at all set the resolution to 640X480.
Expected Results: Working X at 1024X768.
This chip support is broken in RedHat 7.3, too.
No, the chip support is actually not broken. What is broken though
is the BIOS in your laptop. If computer vendors would follow Intel's
published specifications when implementing these graphics chips on
laptops and other hardware, then people would not have these problems.
Somewhere on developer.intel.com is a page describing how many laptop
manufacturers have designed their laptop BIOS's against Intel's specifications.
This is the reason why your video is limited to 640x480. In order to
get beyond that requires one of 2 things.
1) Your laptop vendor to fix their broken BIOS and release a flash update
for it for you to apply.
2) Intel to release the detailed specifications on how to program the
chipset to provide more RAM to the video controller, so that someone
can add this code which should be in your BIOS to the XFree86 video
driver to workaround the broken BIOS problem.
