I use Ubuntu 11.10 with Gnome Shell and have an encrypted home folder. I enabled auto log-in through the system settings/users-admin menu, as I expected it didn't work (because of my encrypted home folder/user I suspect). But now I don't have privileges to mount my eksternal hard-drive, and I can no longer disable the auto log-in function, since the un-lock button in users-admin menu is grayed out. It seems like my users privileges has been degraded. Does any one have an solution to how I disable auto log-in and regain my privileges?
