I updated recently to 12.04. At first, everything worked perfectly. But since today, I get stuck at the login screen. Whenever I enter my password, it says "logging in" but won't continue from there. I don't see anything alarming @dmesg.
Thanks already in advance.
edit: in /var/log/lightdm/x-0-greeter.log I see some critical errors:
CRITICAL: ido_calendar_menu_item_set_date: assertion 'IDO_IS_CALENDAR_MENU_ITEM(menuitem)' failed ... [some debug messages about permission denied to load background] CRITICAL: background_loader_create_pattern: assertion 'image != NULL' failed
edit2: just compared it to a previous, successful login. The only difference I see is this line:
DEBUG: unity-greter.vala:496: Failed to write state: Error writing to file: Bad address
