I am seeing something like this problem with my GMA965 (in my Lenovo
Thinkpad T61) w/ Samsung 243T via DVI or VGA connectors. Xrandr sees
it can do 1920x1200 yet it is stuck at 1280x1024 @ 75hz , which my
monitor then shows out of sync. The problem is definitely with the
intel driver as I can use it fine under Windows Vista with my Thinkpad
via DVI or VGA.
When you try to do anything with xrandr to the monitor .. it does
NOTHING! Can't change the res on it or anything. Now this works
perfectly fine with my Nvidia card in my desktop using xorg "nv"
driver as well as proprietary driver.
I've attached 2 docs to this email showing output data from my desktop
hooked to the Samsung 243T (the good one) .. and my Thinkpad T61
connected to the Samsung 243T
I'm really surprised as I really expected this to just work .. and now
I've had a chance to try it and I'm like WTF!
Docs are attached with xrandr info for everyone's enjoyment (or
someone can figure out what is going on).
Also looking through bugzilla I found something that may "possibly" be related:
https://bugs.freedesktop.org/show_bug.cgi?id=10694
["xrandr_intel_samsung243T_BAD.txt" (text/plain)]
Thinkpad T61 with (965GM) X3100 connected to docking station
hooked up to Samsung 243T via DVI (VGA displays the same behavior):
I am unable to change the resolution of the Samsung 243T. Xrandr will
not do anything to it. It is stuck at 1280x1024 @ 75hz..!!!!!
Tested this under Windows Vista and it works fine, without issue. Samsung 243T
displays at 1920x1200. So it is not a hardware issue!
THIS IS VERY BAD!!!
