Vesa does not detect 1152x864 mode with Intel 865G

I'd like to be able to use a resolution of 1152x864 with xorg. I know this resolution works @ 75Hz in MS land. The hardware is an Intel Springdale-G Integrated (Intel 865(G)) and a Dell M782 monitor. I'm using a dell bios version A06.

My xorg.conf file:

Code:
...
Section "Module"
    Load        "dbe"   # Double buffer extension
    SubSection  "extmod"
      Option    "omit xfree86-dga"   # don't initialise the DGA extension
    EndSubSection
    Load        "type1"
    Load        "freetype"
EndSection

Section "Monitor"
    Identifier  "My Monitor"
    HorizSync   30-85
    VertRefresh 50-160
    DisplaySize 315 240
EndSection

    EndSubsection

Try adding a modeline in your Monitor section. I like using Colas XFree Modeline Generator.

Code:
Section "Monitor"
    Identifier  "My Monitor"
    HorizSync   30-85
    VertRefresh 50-160
    DisplaySize 315 240

ModeLine "1152x864" 104.14 1152 1200 1440 1536 864 866 878 904 #75Hz

EndSection

Thanks for the reply... Adding a modeline and restarting the X server does not seem to work. The xorg log still says:

(II) I810(0): Not using built-in mode "1600x1200" (width too large for virtual size)
(II) I810(0): Not using built-in mode "1280x1024" (width too large for virtual size)
(--) I810(0): Virtual size is 1024x768 (pitch 1024)

Strictly a guess -- is that DisplaySize correct? Typically the dimensions are the standard 4:3 ratio, meaning 320x240. You might consider commenting that line out, or changing 315 to 320. Again, this is only a guess, and it may not have any effect. If that value is known to be correct for your monitor, disregard this comment. -- J.W.

Thanks J.W. I actually just measured it myself and was probably off by 5mm. Nice catch.

It still doesn't fix the resolution issue. Maybe there isn't a fix in Linux. I'm guessing the windows driver talks directly to the hardware while the linux drivers have to rely on the BIOS for settings? Or are modelines supposed to take care of that?

Anyone else experience this issue?

Hmm, a couple of other things to try:

1. Add this parameter to your video driver section (below where you specify the i810 driver): "VideoRAM" 32768
2. Change the default color depth to 16 from 24.

Whether or not those produce the desired result remains to be seen but I'd give them a try. -- J.W.

Thanks again for the response... still didn't work. The messages in the xorg log files are pretty much the same as above. I'm really stumped on this one.
