From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) Opera 7.20 [en] Description of problem: I use an Acer Centrino Notebook with an 855GM graphic chipset. If I select a resolution of 1400x1050. The installer says there is no entry of this resolution in my BIOS and he choose the next smaller one(1280x1024). I asked Acer to add this entry, but they wrote 1400x1050 is not a standard VESA resolution and will never be in the BIOS. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.boot CD1 from test2 2.chose 1400x1050 3. Actual Results: There is a message from the installer. Expected Results: There should be the correct resolution. Additional info: Acer TravelMate 661LMi
The "i810" video driver uses the VESA BIOS to set video modes, and is thus limited to only providing modes that are supported by the video BIOS. Any mode which the BIOS does not support is not useable by this video driver. The only way to provide video modes other than what the BIOS provides, is to program the hardware directly, however that requires access to Intel's video specifications which are not available, so this problem can not be fixed except by Intel or the upstream X developers who have been contracted by Intel to maintain the video driver. There is nothing we can do about this issue until the feature is implemented in the upstream video driver. Closing bug as "WONTFIX" (in lieu of a CANTFIX resolution).
FWIW, here's a workaround ("855resolution"): http://perso.wanadoo.fr/apoirier/
