Public bug reported:
Binary package hint: xserver-xorg-video-ati
I have a sutttle box with a ATI RS480.
with the latest Karmic updates using the open source radeon driver the xserver
is able to detect my 2 monitors.
output from lspci:
01:05.0 VGA compatible controller: ATI Technologies Inc RS480 [Radeon Xpress
200G Series]

S-video disconnected (normal left inverted right x axis y axis)
the VGA--0 works fine and I can use the Ubuntu tool to change resolutions.
If I disable VGA-0 and enable DVI-0, I can't seem to get any image on the
monitor connected to DVI-0.
I tried using the ubuntu Display Preferences tool, but I was not able to
make the DVI-0 connected monitor display any image.
I also tried this on the cmd line
xrandr --output DVI-0 --off
xrandr --output DVI-0 --same-as VGA-0 --mode 1920x1080
but got no results.
only the monitor connect to VGA-0 display any image.
