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 -- X server fails after upgrade Dapper > Edgy https://launchpad.net/bugs/58326 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
