How to recover this (kde crash)

English Applications
#1

Dear all,
I was using kde while all windows dissapeared. I think the problem is caused with the kwin
if for example I launch kwin and the kill it again… the lost windows appear again

(the virtual desktop is lost so all windows appear to the same “window”)

please have a look in the screenshot here how the windows look like

ImageShack® - Online Photo and Video Hosting

my guess is that while I was working kwin crashed and the new one that started automatically just replaced the old ones…

How I can recover from this error? I can not afford a restart as I need the applications running.

I am running kde 4.7.2 (release 5) with 12.1 opensuse.

I would like to thank you in advance for your help

I am not sure if that improves the situation you have on that screen but
you can try a


kwin --replace &

in a terminal like konsole or xterm and see if it is better then.

Nope… it just “covers” everything (like starting a new session) … new applications can be launched but the old ones are not any more visible.

Try use the command
plasma-desktop

Then I have no idea. When I start kwin with the --replace parameter it
just restores all existing windows and their decorations as it is
supposed to.
It looks then as if your problem is not a crash of kwin but something
else crashed.

Thanks all… unfortunately nothing helped… Can you please tell me how I can ask from kde… to log me off… so at least saves my open windows…?

I would like to thank you in advance for your help

When you press ctrl+alt+del in kde the logout dialog should come up,
does this work?

Hi,
Try this two commands
Run this command first

kquitapp plasma-desktop

Then after you run the first command
run the command

plasma-desktop

I have bookmarked this page as I think I am gonna use it in the future. I kept working with the new kwin --replace session and after some time all the windows were restored back (something like 30 mins)… In that case my problem is temporarily solved… I am quite sure though that I will have to visit this page again.

Regards
Alex

You should of course search for the root cause why that happens to you
to avoid this problem in the future (maybe a problem with your graphics
card/driver or similar).

This is true… My problem is that I do not know how this happens… I am quite sure though that there might be something with kwin and multiple sessions.
After I restarted my computer (not only kde) kde restored my previous sessions. Then I tried to see a website (that was already open in firefox), so as I was typing the address the firefox saw that this website is already open and suggested me to get focus of it which I accepted.

As this tab was opened yesterday after issuing kwin --replace all the windows disappeared and my yesterday’s firefox appeared again. I killed it then my normal session appeared… How I can track what is causing this mess?

I would like to thank you in advance fo your help
