Bug Description
Binary package hint: xserver-
When connecting a second monitor to my laptop, the second monitor IS detected by RandR 1.2, albeit not correctly.
the list of available modes:
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 1400 x 1200
VGA-0 connected 1280x1024+0+0 (normal left inverted right) 0mm x 0mm
1280x800 60.0
1280x768 60.0
1024x768 60.0
800x600 60.3
640x480 59.9
1280x1024@85 85.0*
Is locked at 60Hz. The mode 1280x1024@85 is one I added myself, using a custom modeline. It works perfectly well with my monitor, but I would like that kind of thing to be auto-detected.
I found this warning in the log, which I'm fairly sure is related:
(WW) RADEON(0): DDC2/I2C is not properly initialized
I'm attaching the entire Xorg.0.log, as well as a few other files that might be of interest.
