I was affected by this issue as well. That is, I upgraded from natty to oneiric release and upon reboot no X server started. The last message on the console was "Checking battery state", but I expect that's just the last init script that ran and unrelated to this issue. The problem was that no DM was starting even though I could start both lightdm & gdm manually.
After reading the comments in this bug, I ran "dpkg-reconfigure lightdm" and chose lightdm as my DM. This resolved my issue with no other steps required. Fwiw, I was not prompted to choose a DM by the release upgrade process. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/804171 Title: After latest upgrade of oneiric, Lightdm or Xserver not working Status in One Hundred Paper Cuts: New Status in “lightdm” package in Ubuntu: Incomplete Bug description: It seems that, after last upgrade of Oneiric made one hour ago, either Xserver or lightdm doesn't work anymore. Before the login screen Ubuntu prints out some state messages. The last one is "Checking battery state" (mine it is not a portable PC) I have to press Alt+F1, I logged in and wrote "startx". Gnome3 says "Failed to load session "gnome-fallback"" (my pc doesn't support neither Gnome-shell nor Unity3D) and pressing the only button Log Out terminal compares again. Is it possible to rollback last upgrade of Lightdm?
