However, if I click Switch account, the *greeter* does accept the same password. This issue is reproducible either by hitting the Ctrl+Alt+L shortcut key or by runnibg `gnome-screensaver-command -l` This happens after I upgraded from Ubuntu 12.04 to 14.04. I had ATI Radeon HD 3870 with open source drivers, now I have GeForce GTX 750 Ti with NVIDIA proprietary drivers. Same thing.
