So I have a NVIDIA 1080TI so using those drivers, and recently I have had this issue where I login normally but it just goes to a black desktop with only the mouse cursor showing.
Now I know there are 100 related issues with black/blank screen but this one seems different because I can switch to say Alt-F2 tty then back again via Alt-F7 and there is my desktop working as intended.
I will grab the x11 log and past a link below. APCI fails when I do ctrl-alt-backspace to restart the x session, but I don’t believe its related.
At [ 1532.342] I believe is where it just sits and waits at black desktop forever until I do the TTY switching trick, I have had this happen before but its usually gone away.
My xorg nvidia config file for completion.
(note I only just turned on HardDPMS, it makes not difference)
