Light locker black screen

Postby shogun1234 » 2018-09-29 12:57

When light locker takes effect, the screen becomes black. Although I can unlock after typing password. But it's annoying, for instance, typing wrong password needs to keeping pressing backspace for cleanup.

I tried changing theme at **/etc/lightdm/lightdm.conf** to **greeter-session=lightdm-gtk-greeter**, but the result was worse because typing password doesn't unlock the screen and no way to see what goes wrong. I am sure lightdm-gtk-greeter is installed because installation command shows it's installed.

Code: Select all
sudo apt-get install lightdm-gtk-greeter
Reading package lists... Done

lightdm-gtk-greeter is already the newest version (2.0.5-1).
0 upgraded, 0 newly installed, 0 to remove and 38 not upgraded.

Any place to investigate or how to fix the problem?

i am guessing that your screen switches off at the same time the locker becomes active.
this should be adjustable from power manager settings.
