I am not sure what can cause this, but for some users on the machine, KDE completely hangs during login.
Four icons show up, then, when the big K should appear, the screen becomes gray bubbles, and nothing happens.

I've tried deleting ~/.kde4 and ~/.kde, and for one user, I even moved out all his home directory, leaving nothing there. I also verified no procesees are running for that user before the login, and also deleted all the user's files under /tmp.

On the other hand, I have two other users on the machine, which login with no problems.

Here's the .xsession-errors file for that users. Frankly, I can't make the signal out of the noise there - I hope someone in the forum can point me in the right direction.

This is a Gentoo amd64, running latest testing (which usually means upstream stable).

No, that didn't help too.
I recreated the user's home directory as empty, and deleted all the above files, and killed all the user's processes.

I get four KDE icons, then a message about akonadi starting, then a few about nepomunk and then nothing.

Try pressing alt-f2, then typing "konsole" and opening it.

With it open, type in the following and paste the contents of "outfile" here.

Code: Select all

ps aux | grep $USER > outfile
