About two weeks ago my LVM tools disappeared somehow and I lost access 
to lv_home;  after reinstalling the tools, and apparent initial success, 
I could only reboot into Gnome.  I enabled the kde-unstable repo to try 
the new build from there, but still could get only Gnome or the login 
screen.  Xorg.0.log showed many AUDIT messages and clients being 
connected and rapidly disconnected.  I found an earlier reference 
quoting a similar log extract and claiming a cure by adding a section 
"Files"  defining the RgbPath to Xorg.conf, but that was later 
retracted.  I don't have an Xorg.conf.  I'm now on 6.4

Eventually I found that disabling the sshd service permitted normal 
login to kde.  That's not a universal solution, but it lets me do most 
of what I want.
