I have a decidedly old video chip in a laptop (ATI Radeon IGP 345M, circa 2005) and I'm trying to get it to play nicely with a new wide-screen monitor.
The external monitor's native resolution is 1440x900 @ 60Hz. Here's the output of xrandr:
As you can see, VGA-0 (my monitor) has a resolution of 1440x900 @ 59.9Hz, as far as Xubuntu is concerned. I need this changed to 60Hz, because at that refresh rate, my screen flickers awfully with any movement of the mouse.
$ xrandr -q
Screen 0: minimum 320 x 200, current 1440 x 1050, maximum 1440 x 1200
VGA-0 connected 1440x900+0+0 (normal left inverted right x axis y axis) 408mm x 255mm
1440x900 59.9*+ 59.9
1280x1024 75.0 59.9
1024x768 75.1 60.0
800x600 75.0 60.3
640x480 75.0 60.0
LVDS connected 1400x1050+0+0 (normal left inverted right x axis y axis) 305mm x 228mm
1400x1050 60.0*+ 60.0
S-video disconnected (normal left inverted right x axis y axis)
Is it possible to force the resolution to change to 60Hz?
