Bug Description

On ubuntu-mate wiley amd 64 install to the entire disk. then reboot and get away from the keyboard for long enough for the screensaver to activate itself. Then the Ubuntu mate logo shows up as the screensaver. move the mouse to get to the unlock screen enter your password and press unlock. The screen will change then go back to to the screensaver and you can try to unlock again.

Description: Ubuntu Wily Werewolf (development branch)
Release: 15.10

I expected after entering my password to unlock to have the screen unlock. Instead I got taken back to the lock screen until I selected switch user and then logged back into my session in lightdm. Logging in through switch user is a workaround for this problem.

Same problem here with mate under ubuntu-mate wily 15.10.

Temporary solution:
Log to a console and kill mate-screensaver.

The work around for now is to use Switch User and authenticate, this will "log you in" and preserve your desktop session. This bug is fixed in MATE 1.10 which will land in Ubuntu 15.10 soon.

The workaround is broken at least with sddm, with it I get a new TTY and entirely different session for the same user who already has session running in another TTY.

Fix released just moments ago when mate-screensaver 1.10 updates this issue should be resolved. This will also be included in Ubuntu MATE 15.10 beta 1.
