Bug Description
After login into kde 4.1.1 I try to xrandr to change the resolution of a second screen.
The result is Xorg crashes often (>70%) not always and I'm back to the login screen.
The xorg.0.log showed following backtrace:
0: /usr/bin/
1: [0xb7f04400]
2: /usr/lib/
3: /usr/lib/

Saw signal 11. Server aborting.
Graphic card: ati x1400 using radeon driver with dri enabled.
Actual packages on Kubuntu Intrepid:
xorg: 7.4~2ubuntu4
libgl1-mesa-glx: 7.1-1ubuntu3
If you need informations I will provide them.
I have a similar problem. I am using Kubuntu Intrepid on a IBM Thinkpad T42p with ATI FireGL MobilityT2 video card. I also use the opensource driver, in my case the radeon module gets loaded.
Only difference is that using xrandr to enable dual-monitor setup with my external display with
xrandr --output DVI-0 --auto --above LVDS
freezes the complete machine. Only option is to switch off via the power button and reboot. This also roughly happens in 70% of the cases, I try to do it. I have found no backtrace in my xorg.log but I will attach it nevertheless. However, I noticed, that if I kill plasma with
killall -9 plasma
before using xrandr the external display gets activated correctly. Afterward I just reload plasma from the terminal and everything works fine. So, I would guess that this problem might be related to plasma as well.
