Version: unspecified (using KDE 4.4.3) OS: Linux if password is wrong, kdm propose to login again. But after it right password is typed, kdm close graphics window and show text screen. So, in general, we have only one attempt to login by KDM. Reproducible: Always Steps to Reproduce: Choice runlevel '5' and KDM as manager, reboot. Put right login and right password - OK. Exit KDE and login again. Username field is OK - do not touch it, put worng password and press enter. Receice message about password wrong and new prompt to login. Put right password and press enter. Actual Results: KDM hide graphics screen and show text console... No way to continue... Expected Results: KDM accept password and run GUI. For newbie only one way - reboot system. For advanced user it is necessary to switch to different console, login as root and kill kdm process or `killall kdm`. It cause KDM restarting. This bug is affected to kdm in fedora-12 too.
I got same issue on F13 fully updated, curiosity if I fail more than one time , don't happen. This is not easy to debug , any help how I debug this is appreciated .
the daemon.* syslog facility should give some clue. for improved debugging results, please restart kdm with -debug 15. some more details are in the kdm README.
created abrt crash report - https://bugzilla.redhat.com/show_bug.cgi?id=605156 debug -15 doesn't work for me
i said -debug 15, not debug -15
anyway, the original report contains no indication of using the fingerprint scanner plugin, so comment #3 is most likely unrelated.
ok -15 was my typo in this comment, not in system (verified via ps ax) - kdm.log showed only X log, nothing more thanks for pointing to fingerprint PAM, after commenting it out, kdm works well (see my bugzilla report)
too bad that you ignored about 80% of comment #2. but, oh, well, not my problem.
I wonder if is not a intel-drv problem, which kill xserver ? Any non-intel here ?
>> Any non-intel here ? Yes, The same on desktop with GF8800 GTX (proprietary driver).
Created attachment 48103 [details] empty password - first time, no crash
Created attachment 48104 [details] empty password - second time, crash just for completeness' sake (-debug 15, daemon.*)
Created attachment 48655 [details] kdm with -debug 15, daemon.* wrong password - right password , crash kdm with -debug 15, daemon.* After this happen I could reproduce this behaviour , all the times , so you got 2 or 3 , crashes on attach. Also you have a completed backtrace on: https://bugzilla.redhat.com/show_bug.cgi?id=612176
(In reply to comment #12) this message: Jul 7 14:26:32 magix kdm[1747]: Cannot lock pid file /var/run/kdm/kdm.pid, another xdm is running (pid 1692) is just me trying start kdm from console, is not part of the bug.
Looks like another pam-fprintd victim, and likely dup of bug #220404
If you're not using a fingerprint reader, see if yum remove fprintd-pam helps. And after: yum remove fprintd , My tests after this and couldn't reproduce the bug again, but just a few tests.
looking at zejdl's log, it looks like PAM is crashing, so rex' suspicion might be correct. sergio's log is worthless; it doesn't contain any actual debugging information from kdm. i know that some distributions apply completely broken patches from suse, which also may explain the original submission, but i guess we'll never know, as the OP never posted a log. an actual bug in upstream kdm is somewhat unlikely, though.
