I don't know how did you get the values for modeline option but I think they are false: ModeLine "1280x800" 83.91 1280 1312 1624 1656 800 816 824 841 I use gtf to get (in theory :) the good values. gtf horizontal-resolution vertical-resolution refresh So to match 83.91: $ gtf 1280 800 60.32 # 1280x800 @ 60.32 Hz (GTF) hsync: 49.94 kHz; pclk: 83.91 MHz Modeline "1280x800_60.32" 83.91 1280 1344 1480 1680 800 801 804 828 -HSync +Vsync The other values are very different. You should try gtf with a refresh rate of 60Hz (refresh rate for lcd screens). And if there is still "(II) VESA(0): Not using mode "1280x800" (no mode of this name)" in your log, probably your video bios is ugly and cannot display wide resolution with vesa driver. I'm also surprised by this warning "(WW) VESA(0): remove MTRR 0 - 1000". In my log I have "(==) VESA(0): Write-combining range (0x0,0x1000) was already clear". A problem with mtrr? I read there is a nomtrr option (man xorg.conf), perhaps it will fix it. Eric
