Description Kiril Vladimiroff 2010-05-08 12:50:29 UTC

Version:            (using KDE 4.4.3)
Compiler:           Arch Linux x86_64
OS:                Linux
Installed from:    Archlinux Packages

Often, when I'm logging in KDE, the login process freezes at the splash screen, right before(sometimes during) showing the kde logo in it. Sometimes the default activity gets loaded, but everything it's useless, anyway.

My mouse starting to move choping. Shortcuts, icons, plasmoids, even alt+f2 doesn't work at all. The only thing I can do is restarting the X server and trying to log again(sometimes it does with success, though).

It seems that there is no crash at all, so I don't know if there is a way to show here some backtrace or something. I could only attach the result from "gdb -p $(pidof plasma-desktop)", executed from tty1, after one of freezes.

This is the output from gdb -p $(pidof plasma-desktop)[executed from tty1] while login proccess get freezed.

no debugging symbols; please install the debug packages for KDE and reproduce. (also, please paste the resulting backtrace directly into the comment instead of creating an attachment.) thanks! :)

Comment 3 Kiril Vladimiroff 2010-05-09 14:06:27 UTC

I have all debug packages(and I have reported bugs with them, too), but in this case it seems there is no crash at all. Just everything stop responding and mouse is moving like choping.

I don't know how could I attach some debugging output. The only thing I could do is record it with a video camera.

.xsession-errors

Comment 5 Kiril Vladimiroff 2010-05-12 13:58:16 UTC

I've just figure out, that I could paste here the content of .xsession-errors. I've deleted the file and tried to reproduce it. 

And here is the result in the file after freezing up:
<<It was too long, so I've attached it in a file>>
Am I the only one who doesn't see anything wrong in it?

Comment 6 Kiril Vladimiroff 2010-05-12 14:58:09 UTC

Also...it seems that this issue is not reproducable, when the "On Login" option in System Settings -> Advanced -> Session Manager is set to "Restore previous session". Which works for me, for now.

Comment 7 Aaron J. Seigo 2010-05-14 01:08:52 UTC

what was "On Login" set to previously? or was that setting ("Restore previous
session") causing the one that was problems for you, and now it isn't?

Comment 8 Kiril Vladimiroff 2010-05-16 02:00:09 UTC

It was "Start with an empty session", than I changed it to "Restore manually saved session". With both I had that issue. 

It works fine as well only with "Restore previous session"
