Hi there,
I'm running a fresh install of Ubuntu 8.10 on a Dell GX620 Optiplex. It has one DVI output on the back connected to DVI to VGA dongle to a 17" SONY flatscreen monitor.
I've previously had this setup running Windows XP at a resolution of 1280x1024 and would like this resolution again.
However when I run "Screen Resolution" I see two monitors attached (there's only one). I can only see what's on "Unknown" which shows me a limited list of resolutions to choose from, whereas "SONY 17" shows the list I would expect. But setting "Unknown" to "Off" and "SONY 17" to some resolution causes my monitor to turn off.
Here's some output from various things in the hope it might aid diagnosis:
xrandr:
Screen 0: minimum 320 x 200, current 1152 x 864, maximum 2432 x 1024
VGA connected 1152x864+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1360x768 59.8
1152x864 60.0*
1024x768 60.0
800x600 60.3
640x480 59.9
TMDS-1 connected (normal left inverted right x axis y axis)
1280x1024 60.0 + 60.0 60.0
1600x1024 60.2
1440x900 59.9
1280x960 60.0 60.0
1360x768 59.8
1152x864 60.0
1024x768 60.0
800x600 60.3 56.2
640x480 60.0 59.9

Any thoughts/help/suggestions would be greatly appreciated.
