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.
Any advice?
Ps I have switched from lightdm to GDM because lightdm gave many more problems than GDM now does.
