I use KDE 4.12.4 on Fedora 20 and I did a system update yesterday and
am currently on Kernel 3.14.3-200.fc20.x86_64. Whenever I log into a
desktop that is not KDE, KDM crashes. I get a black screen for a
second and it goes back to the Login Screen. This is the log of
journalctl -k :
http://ur1.ca/hbc9b when I attempt to log into MATE.
You can see on the last couple of lines that there is a segfault. And
this is log from when I log into kde:
http://ur1.ca/hbcan.
I did get an SELinux warning about kdm not being allowed write access
to a directory but I'm not sure that's relevant. The problem is that
GDM does work and with GDM I *can* log into to any desktop.
I am using nvidia drivers if that's useful...
Any help would be greatly appreciated.
