I am facing this error after I have upgraded my Kali Linux to the latest version that is (4.19.0-kali1-amd64).
uname -a
4.19.0-kali1-amd64 #1 SMP Debian 4.19.13-1kali1 (2019-01-03) x86_64 GNU/Linux
I have been using lightdm version (1.26.0). Problem is when I try to wake my laptop from the sleep mode, then screens become black and the only option I have is to turn the laptop off and on again. During the black screen, I cannot do anything.

I have already tried to remove the light-locker and its settings that didn't work, I have tried to change to gdm3 that didn't work either.
Anyone can help, please?
