Bug 198043

I can confirm: Thinkpad X41 with:
00:02.1 Display controller: Intel Corporation Mobile 915GM/GMS/910GML Express
Graphics Controller (rev 03)

Results in a 'panning' 1280x1024 screen within a 1024x768 display.

Here are first few lines of /var/log/gdm/:0.log:

Display 'returns to normal' (i.e., 1280x1024 display as 1280x1024) when I revert
to xorg-x11-drv-i810-1.6.0-5.i386.rpm.

Here is :0.log when I run with 1.6.0-5:

Jurgen's bug is actually a bug against Mesa, since that's what provides i915_dri.so.

Tom, your issue is a different bug, I've cloned it off as bug #198062.  Please
follow it there.  Please note that the summary of this bug (about software
rendering) had nothing to do with your issue (bad modesetting).

the missing symbol problem is solved with the latest xorg update:

drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 9, (OK)
drmOpenByBusid: Searching for BusID pci:0000:00:02.0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 9, (OK)
drmOpenByBusid: drmOpenMinor returns 9
