Force interpolated resolution with Intel 945GM

Hello together!

I'm currently trying to get a little more Linux on my little HTC Shift http://www.htc.com/www/product/shift/overview.html. Only two things won't work: WLAN does not work (I will discuss this in another thread, if I can't solve that by myself ;) ) and the x server is not able to display a larger resolution than the display's native one.

But why would I want an interpolated resolution? The answer is simple: the native resolution is only 800x480, which means that there's not very much space left even with a tilling window manager like wmii. I know the card and the display support higher resolutions, because I normally run Vista in 1024x600 which is a good compromise between size and interpolation. But I'm not able to get X to display that resolution.

Currently the important parts in my xorg.conf look like this:

Section "Monitor"
  Identifer  "Monitor0"
  VendorName  "Monitor Vender"
  ModelName "Monitor Model"
  Modeline "1024x600" 49.00 1024 1072 1168 1312 600 603 613 624 -hsync +vsync
  Option "PreferredMode" "1024x600"
EndSection

Section "Device"
  Identifer "Card0"
  Driver "intel"
  VendorName "Intel Corporation"
  BoardName  "Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller"
  Option  "Monitor-LVDS" "Monitor0"
  BusID "PCI:0:2:0"
  Option "DDC" "false"
EndSection

Section "Screen"
  Identifer "Screen0"
  Device "Card0"
  Monitor "Monitor0"
  SubSection "Display"
    Viewport 0 0
    Virtual 1024 600
    Depth 1
    Modes "1024x600"
  EndSubSection
  SubSection "Display"
    Viewport 0 0
    Virtual 1024 600
    Depth 4
    Modes "1024x600"
  EndSubSection
  SubSection "Display"
    Viewport 0 0
    Virtual 1024 600
    Depth 8
    Modes "1024x600"
  EndSubSection
  SubSection "Display"
    Viewport 0 0
    Virtual 1024 600
    Depth 15
    Modes "1024x600"
  EndSubSection
  SubSection "Display"
    Viewport 0 0
    Virtual 1024 600
    Depth 16
    Modes "1024x600"
  EndSubSection
  SubSection "Display"
    Viewport 0 0
    Virtual 1024 600
    Depth 24
    Modes "1024x600"
  EndSubSection
EndSection

The xorg.conf was initially generated with "Xorg -configure" and intensively edited by me :lol:

In the Xorg.0.log the only interesting line (at least in my opinion) is "(II) intel(0): Output LVDS using initial mode 800x480", although it seems to successfully read the PrefferedMode and DDC lines.

If there is no chance in using the intel driver, might there be one by using the i810 one in conjunction with 915resolution? Can they be used with current (up to date) x server?

Regards,
Sven
