XRANDR outputs

[Russell Shaw]

Hi,
After a system upgrade, xrandr no longer reports two monitors connected to the 
video card. I get:

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 400, current 1600 x 1200, maximum 1600 x 1200
default connected 1600x1200+0+0 0mm x 0mm
    1600x1200       0.0*
    1280x1024       0.0
    1152x864        0.0
    1024x768        0.0
    800x600         0.0
    640x480         0.0
    720x400         0.0


Both monitors (one DVI, other VGA) are showing the same image, but the second 
monitor can't handle 1600x1200.


On debian/unstable i have:

libdrm-radeon1:i386  2.4.46-3  i386
Userspace interface to radeon-specific kernel DRM services -- runtime

xserver-xorg-video-radeon  1:7.2.0-1+b2  i386
X.Org X server -- AMD/ATI Radeon display driver

xrandr 1.4
