[Bug 654660] Re: Maverick xorg results in "out of range" error w/Intel i945 & 22" LCD
The output of "xrandr --verbose -d :0" is so long that I can't see the
top portion, which I can see after playing is what we really need to
see, but I did manage to get the output of "xrandr -d :0". This is the
broken one:
ubuntu@ubuntu:~$ xrandr -d :0
Screen 0: minimum 320 x 200, current 1600 x 1200, maximum 4096 x 4096
VGA1 connected 1600x1200+0+0 (normal left inverted right x axis y axis) 474mm x 297mm
1680x1050 60.6+ 74.9
1600x1200 75.0* 60.0
1400x1050 74.9 60.0
1280x1024 75.0 60.0
1280x960 60.0
1152x864 75.0
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 72.8 75.0 66.7 60.0
720x400 70.1
This is what it should be (copied from a Beta Live CD):
ubuntu@ubuntu:~$ xrandr -d :0
Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 4096 x 4096
VGA1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 474mm x 297mm
1680x1050 60.6*+ 74.9
1600x1200 75.0 60.0
1400x1050 74.9 60.0
1280x1024 75.0 60.0
1280x960 60.0
1152x864 75.0
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 72.8 75.0 66.7 60.0
720x400 70.1
So it's normal to have a mode for 1600x1200@75.0Hz but it shouldn't be
selected, in fact 1680x1050@60.6Hz is shown as the preferred mode but
possibly the bug in g-s-d is resulting in 1600x1200@75Hz being selected?
I'm going to shut down this monitor and disconnect it for a while
because it's acting flaky now :^( It did this once before while trying
to figure this out and disconnecting it for a few hours did the trick,
so I'm hoping that'll do it again :^)
