Hi all,

Yesterday I had the brilliant idea to upgrade to 4.6 from the kubuntu ppa repositories, and what do you know, yep, system messed up. I know, I know, early adopters...

So what's the problem? System boots nicely, kdm starts no prob, but when I log in, for a very short instance, a white window appears in the left corner (error message I suppose, but it's too fast to see anything), then the screen goes black annd returns to the kdm login. Tried moving my .kde and .kde4 directories (always a good bet when upgrading), no change. Checked the xorg logs, no errors there, also not when I disable kdm and run startx. When I look into /var/log/kdm.log , that's a different story. Apparently there's a problem connecting to dbus, so I suspect that's where the cause is to be found. Here's the log:

Still, when I check dbus seems to be running:

Code: Select all

~$ sudo service dbus status
dbus start/running, process 814


so why isn't it connecting? Any ideas? I'm running kubuntu 10.10, formerly with kde 4.5.1, now with 4.6.0.

See if you're missing some crucial packages - you're not the only one who's had problems after upgrading on Kubuntu: viewtopic.php?f=66&t=92867#p186340

WTF???? Who packaged this thing?!? Even the bloody widow manager is missing!
