Created attachment 503044 [details] X info Description of problem: Version-Release number of selected component (if applicable): Fedora 15, KDE Desktop How reproducible: Use Lock Screen Function in KDE. First time it works, hitting a key you get the prompt to type in your password and you are back to the desktop OK. Do it again, the screen goes black, you lose your xsession. CTRL-ALT-BACKSPACE is needed to recover. Steps to Reproduce: 1. Use Console Lock PADLOCK Widget 2. Xscreensaver starts, then enter password to get back. 3. Do 1 &2 again. Black Screen results. Actual results: Black Screen Expected results: Should display the desktop after unlocking it. Additional info: Fedora 15
Sorry, however more info is needed to understand what is happening on your X session. First of all, KDE has its own screensaver, kscreensaver. Are you sure that you are actually using xscreensaver instead of kscreensaver or something else?
( To check above, please post the results of following commands: $ rpm -qa | grep screensaver | sort $ ps auwwx | grep screensaver )
[root@kali ~]# rpm -qa | grep screensaver | sort gnome-screensaver-3.0.0-1.fc15.x86_64 kdeartwork-screensavers-4.6.3-1.fc15.x86_64 xscreensaver-5.14-1.fc15.x86_64 xscreensaver-base-5.14-1.fc15.x86_64 xscreensaver-extras-5.14-1.fc15.x86_64 xscreensaver-extras-base-5.14-1.fc15.x86_64 xscreensaver-extras-gss-5.14-1.fc15.x86_64 xscreensaver-gl-base-5.14-1.fc15.x86_64 xscreensaver-gl-extras-5.14-1.fc15.x86_64 xscreensaver-gl-extras-gss-5.14-1.fc15.x86_64 [root@kali ~]# ps auwwx | grep screensaver root 2763 0.0 0.0 103428 856 pts/0 S+ 15:12 0:00 grep --color=auto screensaver [root@kali ~]# )
I only set the screen saver from within KDE. (Settings Control Panel) I do not independently launch xscreensaver separately. -gc
And how did you set screensaver on KDE "Control Panel"? Also, from the output of ps no screensavers seem to be running. Would you relogin to KDE session and try "$ ps auwwx" again?
Well, kde has its own service for launching a screen saver. You won't see it running, unless the service tracking the idletime says its time to launch it. Secondly, I would like to point out, KDE desktop will use: kscreenlocker to unlock the console on the root window for keuphoria.kss, which is launched as the screen saver on the root window. -gc
Okay, thank you. Changing the component to KDE ones
Sounds like X is crashing, i.e. a graphics driver bug. What graphics driver are you using?

The black screen when it does happen allows me to CTRL-ALT-BACKSPACE to kill the session. So I think it might be a kwin compositor problem. I checked the logs and did not find any output whatsoever of anything describing what happened. So I don't think it is a kernel problem, or a X problem otherwise I wouldn't be able to continue using my machine. -gc
Finished testing the latest ddx module for ATI video/X. The last ati-ddx update I received has resolved this problem. It also fixes full screen mode in Flash and Stellararium. -gc
