Re: kubuntu won't start
Not really providing solution, sharing experience.
Did you install some fresh updates ?
Yesterday I had some problems running KDE session after upgrading system,
It said, some other instance ( can't remember correctly what) was started before d-bus. KDE desktop froze on log-in.
I logged into Xfce session and did another update-upgrade, things got smooth.
Read in Phororix, KDE is pushing in 4.13 upgrades before the freeze, guess cause of that some unstability will creep in.
