Comment 0 for bug 1448677

This is for kubuntu. I just upgraded from 14.10 to 15.04 using `do-release-upgrade`.
As far as I could tell, there were no errors during the upgrade process.

I'm using sddm. On startup, I get the login screen, I enter my password,
then I see the progress bar briefly before the screen flickers and ultimately returns me to
the login screen.

I'm looking at syslog, and I see some suspicious messages:

Any idea where I should go from here?

Thanks,
