Xfce: Black screen after resuming and unlocking from standby

Postby klapstul » 2019-08-31 07:46

After the upgrade to Debian 10, standby no longer works as it was working. I am using Xfce and lightdm. Xfce is configured to go to standby after closing the lid. When I open it again, the lightdm login screen shows up as expected, but once I submit my credentials, the screen suddenly turns black. However, I am still able to login into a terminal via Ctrl + Alt + F1.

The strange thing is that once I trigger standby mode via the application menu and then close and reopen my lid again, unlocking the screen works totally fine. Any ideas of what is going on here?

When I set the action for closing the lid to "lock screen", I seem to encounter this bug: https://github.com/the-cavalry/light-locker/issues/114.

I just posted this in another topic as well. This issue has an easy fix. Create 20-intel.conf under /etc/X11/xorg.conf.d/ It is possible you have as well to create directory xorg.conf.d
Code: Select all
/etc/X11/xorg.conf.d/20-intel.conf

Then you add the following in 20-intel.conf and reboot your machine to have the issue solved.
Code: Select all
Section "Device"
 Identifier "Intel Graphics"
 Driver "intel"
EndSection
