Comment 9 for bug 58326

Same problem (or result) today after upgrade via apt-get on a Compaq 900 laptop.

Rebooting after the upgrade fails at the Xserver. Trying startx from the command line gives the following errors:

X: warning; process set ti priority -1 instead of requesting priority 0. giving up.
xinit: Connection refused (errno 111): unable to connect to X server
xinit: No such process (errno 3): Server error.

using sudo startx, I just get

xinit: server error
