Same issue for me after fresh install of 11.10 64bit. I only have this issue on an Asrock H61M/U3S3 Motherboard with onboard Intel graphics (if this matters), other desktops/laptops with nvidia or ati seem to work fine.
The strange thing is that it sometimes does work correctly, I'd say 3/4 times it fails to show the login screen. It stops at "Checking battery state" CTRL-ALT-F1, logging in and running "sudo /etc/init.d/lightdm restart" works every time, but is very annoying to say the least. What I have tried so far: - install lightdm-gtk-greeter (was not installed) - install unity-greeter (was already installed) - sudo dpkg-reconfigure lightdm (same errors as in comment 6) - sudo rm -r /var/run/dbus; dbus-daemon --system - removing the ~/.Xauthority file - reinstalling/replacing nvidia drivers is no option since this is intel, but it is suggested many times I did check some logs, but am not sure where to look and if this is related: - /var/log/lightdm/lightdm.log - Stopping X local seat, failed to start a display - /var/log/lightdm/x-0-greeter.log - WARNING: unity-greeter: Fatal IO error 11 on X server :0. - /var/log/Xorg.0.log - No screens found Looked up the intel graphics specs: lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) I would like to see this solved, so if anyone needs more information, just let me know and I will do my best to gather it for you. -- 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/834592 Title: System hangs during boot with "Checking battery state" on screen Status in “lightdm” package in Ubuntu: Confirmed Bug description: After some digging it appears that lightdm isn't starting properly. One fix appears to be Ctrl+Alt+F1,user and password and startx but I fixed it by switching to using GDM - sudo dpkg-reconfigure -plow gdm. This happened after I ran updates on Wednesday of this week.
