Hi,
I am experiencing a very annoying issue : several times a day my display hangs : no more refresh of any windows.
The only solution is to restart X (whether ctl+alt+backspace or init 3->5…)
Actually I’d rather say that X is still working, but it is not automatically refreshed anymore.
The window content is only refreshed when it gains focus. To refresh my window again, I have to switch to another window and switch back to my window. Then its content is updated… once. I have to toggle focus again for next refresh.
Let’s give an example : Konsole. When the issue is happening, no more refresh of Konsole content. But still the application is active. I can type any command, and execute it. Of course, I have to toggle focus in/off to watch results…
I dont have the single idea what is the faulty component : issue with graphic card drivers ? Plasma thing ? kdm ?
At least I would be happier if someone could tell me which process(es) I should kill/restart to solve my issue, instead of restart entire X environment (and loose all my running tasks… It happens I have to wait till an important task is performed before restarting X. So many minutes (if not hours) to do the toggle focus game… >:( ).
I am running OpenSuSE 11.4 x64 and KDE 4.7.0.
I have enabled desktop effetcts, and especially Desktop Cube Animation (and btw, the Animation is still working fine, which is another way for me to refresh the whole desktop content…).
I have QuadCore Xeon CPU, 3GB RAM and nVidia Quadro NVS 280 PCI-E/Quadro FX 330. With 173.14.30 nVidia drivers (any further release would ignore my GPU model…).
Thank you for your support !
