I've upgraded my Lubuntu distribution to the 3.5.0-26-generic kernel and after rebooting, LXDE is not starting up anymore. I had to revert to 3.5.0-25-generic, which still works. Any suggestions on how can I fix the problem?
Thanks in advance.

Did you do anything special to upgrade the kernel or was it just by way of regular updates? I'm asking because I'm using Lubuntu 12.10 and have "3.5.0-26-generic" which hasn't caused a problem. What exactly happens for you? – user25656 Mar 23 '13 at 12:06

If you have an SSD this might help: In /etc/init/lightdm.conf add just above "exec lightdm": sleep 2

If you find file ~/.Xauthority owned by root then do this: rm -f ~/.Xauthority sudo service lightdm restart
