Since kernel version 4.10.6 I've the problem that when I try to log in after inactivity it only shows the mouse cursor on a black screen.
I can switch to other ttys (including the GUI login “tty1” (
Ctrl+Alt+F1)), but everytime I switch to “tty2” I get the issue back. When I try to log in, it just switches to the second tty and the issue is still there. I tried testing whether I can get this issue when I lock the screen actively (and even leave it be for a few minutes) but it didn't cause the issue.
At the moment my workaround is to use it with an outdated kernel still installed (4.9.17) but every kernel since (4.10.6, 4.10.8, 4.10.9 and 4.10.10) show this error.
