From time to time xscreensaver locks screen on no activity in a way that the screensaver itself is not visible (it only overlaps desktop background), mouse can be moved, but the system does not seem to respond to clicks or keyboard. All this is quite natural as the system simply expects you to enter your password in order to unlock the screen. But it is not visible, as stated above.
What WM/DE, what application? Can it be easily reproduced?
KDE 3.5.8 In order to reproduce it, I just have to leave the PC idle for some half an hour. The applications that usually stay on the foreground are Thunderbird, Gkrellm, OpenOffice.org and Firefox.
What XOrg version and video driver? Try to run xscreensaver with -verbose option and show log.

Created attachment 2251 [details] Run with the -verbose option and waited until the bug reproduced itself.
Лёш, а мне сегодня с утра пришлось опять переключаться в консоль и килять xscreensaver -- не отзывался. В логе при этом было лишь: Nov 3 13:02:43 pad xscreensaver: pam_tcb(xscreensaver:auth): conversation failed Nov 3 13:02:43 pad xscreensaver: pam_tcb(xscreensaver:auth): Unable to obtain a password Недавно он в кнопку открывалки вместо "OK" писал "FAILED" чего-то там. Передай мужикам -- уже сломано, пора чинить ;-)
(In reply to comment #6) > Nov 3 13:02:43 pad xscreensaver: pam_tcb(xscreensaver:auth): conversation failed Вообще-то его надо было перезапустить после обновления до >= 5.02-alt1. Там поменялась работа с pam. И проверить /etc/pam.d/ на тему .rpmnew, потому как %config(noreplace).

(In reply to comment #9) sudo rpm -Vf /etc/pam.d/xscreensaver И вообще, к этому багу оно отношения не имеет, а '"FAILED" чего-то там' означает что xscreensaver не был перезапущен после обновления.

Was it _locked_ again? Is xscreensaver log lost? I have no ideas. Reported upstream...
From: Jamie Zawinski <jwz@jwz> The answer is right there in the bug report -- some other app has the keyboard grabbed. I have no idea what that app is, or why, but it's impossible for xscreensaver to lock the screen if it's unable to grab the keyboard.
Is flash plugin installed? Is there any flash content somewhere in browser?
As far as I see, the conflict is that both KDE screensaver and xscreensaver are activated. And the latter doesn't work properly under KDE. Actually, it should be disabled, but as far as I can see it is invoked from within somewhere around /etc/scriplets.d.
xscreensaver packages does not contain any autostart scripts nor XDG autostart desktop files. Two screensavers doesn't play well, but it's not xscreensaver's problem.
