Xorg.0.log

I'm running Gentoo and just updated from xorg-server 1.3 to 1.5.3, and along
with that the ATI driver updated to 6.12.1. I also tried 6.12.2 to see if that
helped. I'm running on an ATI branded Radeon 9500 Pro / R300.

When I fired up the new server, I noticed that my virtual screen panning (the
xorg.conf Virtual keyword) simply didn't work. I tried using Xorg -configure to
generate a clean config file and added the line (Virtual 2560 1600) and still
got nothing. I tried changing the argument to something invalid (Virtual
2560x1600) and got a syntax error from the server right away.

There are references in the Xorg.0.log file to this virtual screen size, it
just won't do any panning to use that size. If I run xrandr from the command
line, I get:

Screen 0: minimum 320 x 200, current 1600 x 1200, maximum 2560 x 1600
VGA-0 disconnected (normal left inverted right x axis y axis)
DVI-0 connected 1600x1200+0+0 (normal left inverted right x axis y axis) 367mm
x 275mm
   1600x1200      60.0*+   60.0  
   1400x1050      60.0  
   1280x1024      75.0     60.0     60.0  
   1280x960       60.0  
   1152x864       75.0     75.0  
   1024x768       75.1     75.0     70.1     60.0  
   832x624        74.6  
   800x600        72.2     75.0     60.3     56.2  
   640x480        75.0     72.8     75.0     60.0     59.9  
   720x400        70.1  
S-video disconnected (normal left inverted right x axis y axis)

So the server kind-of realizes that I've set the virtual screen size, and just
doesn't pan to use it the way that previous versions have done. This has worked
for me with X since the darkness of time (XFree86).
