After upgrading to 12.04.1 LTS (from the previous LTS) my ubuntu will at
times fail to show the login screen. Roundabout 4 out of 10 times of booting
the "Ubuntu five dots"-screen disappears, no login screen (GDM) appears but
only tty1, with "login: ".
If I then login and do "sudo gdm"
I get the message:
failed to acquire org.gnome.displaymanager
could not acquire name; bailing out.
Whatever I try I can't solve this problem. A reboot (or two or three)
may finally result in the normal GDM-login screen and Ubuntu working
normally.
Ps I have switched from lightdm to GDM because lightdm gave many more
problems than GDM now does.
Jeet suggests I report this as a bug
