I'm having a problem with a normal reboot of Ubuntu 9. Ever since an accidental bad restart, the GUI has not loaded during boots. I've tried to load it on the command prompt with startx, which produces nothing, and service gdm restart, which produces this error message:
restart:Rejected send message, 1 matched rules; type="method_call", sender="1.21" (uid=1000 pid=1517 comm="restart) interface="comm.ubuntu.Upstart0_6.Job" member="Restart" error name="(unset)" requested_reply=0 destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init"))
My machine runs Ubuntu 9 64bit.
