Bug Description
Ubuntu Karmic Koala
VGA: Radeon HD 4550, proprietary fglrx driver
I am using a dual screen setup with two TFTs in portrait mode, DFP5 is right of DFP1, which I activate with
"xrandr --output DFP1 --mode 1920x1200 --rotate left --output DFP5 --mode 1920x1200 --rotate left --right-of DFP1"
After that, xrandr correctly shows that DFP1 starts at 0x0:
"DFP1 connected 1200x1920+0+0"
and DFP5's origin is shifted 1200 pixel to the right, so starts at 1200x0 :
"DFP5 connected 1200x1920+1200+0"
Now there is a one pixel thick column on the left edge of the left screen. It's in a ubuntu-
This bug was present in Jaunty and still is after upgrading to Karmic
Whoever assigned this to fglrx-installer: I don't think this is related in any way to fglrx.
I just switched to open source "radeon" driver. That got me rid of some other weird stuff (a 'ghost mouse cursor' in the left screen, when the real one was in the right one, and an area along the right border of the left screen where the cursor simply vanished)
But the problem descibed in this bug is the same with driver 'radeon'. So it's either an ati hardware thing or related to gnome/xserver/...
