[xubuntu] lightdm kicks out of the session after 14.04 upgrade

[Sunbriel]

Today a notification about the 14.04 upgrade popped up on my working 13.10 Xubuntu installation. Decided to go for it, let it install and do its bidding. After downloading/removing/replacing stuff, a reboot was requested. I agreed on this part of the standard upgrade procedure. Xubuntu booted up, and so I went on with logging in to my account. I logged in successfully, desktop started loading, but after a couple of seconds I was kicked out of the session. I tried all the tricks on the internet I stumbled upon, but none worked. I am able to log in to Guest account with no problem. I have no idea what is going on and would like to fix this without having to do a fresh installation. Any and all instructions and help are welcome.

Edit1:

I ran " cat .xsession-errors " and this is the output:


openConnection: connect: No such file or directory

Script for ibus started at run_im.

Edit2:

Managed to solve it by myself. Since I saw Xorg is causing problems, I downloaded NVIDIA drivers and reinstalled them. The problem is fixed.
