Bug 16203 – X freezes when logging out of kde 3.1

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Felix Rodriguez 2003-02-22 19:55:43 UTC]

X occasionally freezes when I logout as a user from a KDE session. This happens 
whether I logout to login as a different user or logout to shutdown the computer. 

Reproducible: Sometimes
Steps to Reproduce:
1. Logout of KDE 3.1 
2. Choose Turn off computer or 
3. Login as different user 
Actual Results:  
X freezes with cursor as hourglass. 

Expected Results:  
If choosing Turn off computer OS should go through shutdown sequence. 
If Login as different user should see KDM login screen.

Do you use kdm? Do other DEs (gnome etc) work? Does restartig the X server 
(xtrl-alt-backspace) work? 
Try logging the output of startkde: start an X server, and from a vt run startkde. See what it 
tries to do last before X hangs. If the freeze means you can't switch back to the vt pipe its 
output to a file. 

[Comment 2 Felix Rodriguez 2003-03-12 20:39:34 UTC]

I use only kdm. When it locked up again I hit ctrl-alt-bkspace and it popped me 
out of X to the first vt. I tried running startkde from the vt with and without X 
already running. In both instances X did not startup. 

[Comment 3 Dan Armak (RETIRED) 2003-03-19 11:35:04 UTC]

startkde won't start the X server, you have to start it manually and export DISPLAY=0:0 
before running startkde.

Ok I think I know what's going on. X is not freezing. I'm just getting the gray 
screen when I logout of KDE instead of getting the kdm_greet screen or shutting 
down. KDE is not communicating with KDM on logout like it should. The only 
problem is it only happens occasionally. It doesn't happen all the time. 

[Comment 5 Paul de Vrieze (RETIRED) 2003-04-23 09:35:06 UTC]

Looks like kde doesn't cleanup well. Could it be that you run tmpreaper or some similar app? If so configure it to ignore the kde dirs, as without them kde cannot communicate well to itself and will display this kind of behaviour.

[Comment 6 Paul de Vrieze (RETIRED) 2003-06-08 09:36:44 UTC]

Is this now fixed?

[Comment 7 Felix Rodriguez 2003-06-08 20:41:58 UTC]

No it is not fixed. I do not have anything such as tmpreaper running on my 
machine. It only happens occasionally. When it does happen I notice that there 
are two kdm processes still running and one of the kdm processes can't be killed 
even with a kill -9. Could it be that the kdm process is stuck in kernel mode and 
can't be killed. 

[Comment 8 Felix Rodriguez 2003-06-18 05:02:33 UTC]

Ok. I think this bug can be closed now. I recreated my XF86Config file by running 
xf86cfg instead of xf86config. Now I have no problems on logout. I guess there 
was something wrong with the other configuration file.

fixed for the reporter
