screen saver system freeze after some time

[Dark Draco]

Binary package hint: gnome-screensaver

The screensaver crash after some time (like an hour or maybe a half) when i try to unlock the PC. When the password dialog should appear the screensaver freeze but the mouse is visible and moveable, the system look like it's working when i press shortly the power button but i have to reset it over the button to use the PC again

I have the same issue. I can fix it by changing terminals (alt-ctrl-F1) and pkill gnome-screensaver

back on my gnome session (ctrl-alt-f7) I'm back on my desktop
