When locking the screen or whenever the screensaver starts automatically, I cannot log in again, but my system completely freezes and I have to restart the computer. In most cases I was able to do the restart by pressing Alt-REISUB, in some cases however I had to do a hard reset. This is a new bug in zesty (Ubuntu 17.04). In the previous version everything worked fine. I tested both the upgrade and a fresh new installation on the same computer. Package is gnome-screensaver version 3.6.1-7ubuntu5.

I attach an excerpt from my syslog. Hope this might help to find the bug.

I installed zesty on another computer (laptop) as well and there the bug did not appear. So I assume it has something to do with the installed graphics card or graphics driver. Installed graphics card in this case is: NVIDIA Corporation GF108 [GeForce GT 630] (rev a1).
