Public bug reported:
Binary package hint: xserver-xorg-video-intel
I am running Gutsy and using xserver-xorg-video-intel 2:2.0.0-1ubuntu2
on a Dell Latitude X300.
When using a LCD monitor on the external output, the resolution is
correctly set to 1280x1024 (instead of the native 1024x768) but the
display is padded to the left, leaving like 50 pixels of a black stripe
on the right edge. The "auto adjustment" button on the monitor didn't
help.
Inspecting the differences, here are what the monitor OSD reported with the
i810 driver:
80.0kHz 75Hz PP 1280x1024
And the intel driver:
80.5kHz 75Hz NP 1280x1024
Looking like the intel driver chosed a too high resolution, I downsized
it to 60 Hz and it fixed the black stripe problem.
So the bug is either the intel driver is too optimistic on the monitor
capabilities, or the monitor is lying.
I set no horizontal or vertical frequency in the xorg.conf, neither a
modeline.
I can provide xorg.conf, Xorg.0.log with i810 and intel drivers, compile
and test patches.
