Description Benjamin Schindler 2007-10-09 02:22:54 UTC 
I'm using xf86-vdeo-ati-6.7.195 (r300). When I connect my secondary screen, nothing happens (no change in Xorg.0.log. When I execute xrandr, I get: 

Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 1400 x 1200
VGA-0 connected (normal left inverted right x axis y axis)
   1280x1024      60.0 +   75.0     59.9
   1152x864       75.0     74.8
   1024x768       75.1     70.1     60.0
   832x624        74.6
   800x600        72.2     75.0     60.3     56.2
   640x480        75.0     72.8     66.7     60.0
   720x400        70.1
DVI-0 disconnected (normal left inverted right x axis y axis)
LVDS connected 1400x1050+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1400x1050      59.9*+
   1024x768       60.0
   800x600        60.3
   640x480        59.9

However, as seen in the output, the screen is not turned on

I'll attach my Xorg.0.log

Thanks

xorg log

The output regarding my connected screen only appeared after executing xrandr. I don't know whether this is intentional, but I doubt it
Comment 2 Michel Dänzer 2007-10-09 02:28:54 UTC 
You need to enable it explicitly, e.g. with

xrandr --output VGA-0 --auto

Okay, that's bad... :) - that worked. 
However, I would like to say that I have not found one single place where this is documented. I have not found a single document telling me how to use xrandr-1.2 besides xrandr --help. At least a manpage would be nice... If there would have been one, this bug report probably wouldn't exist... 

Cheers, and thanks

Okay... now there is a manpage... please ignore my remark above... now I really feel bad
