Bounty: 100
EDIT: This was my first bounty question… I thought the bounty would frame my description like it did in the prompt. THIS PROBLEM IS NOT RESOLVED – instead I was indicating what the problem resolution would look like
Specs
Display Manager: lightdm 1.30.0
Desktop Environment: gnome 3.36.3
Problem/Background
Once I login, all I can see (for at least a minute) is the wallpaper and mouse. Eventually the rest of the desktop environment is loaded and everything is good to go. If I log out and back in, I don’t have the same issue I do at startup.
Originally I thought the problem was lightdm but it turns out if I switch to gdm3 I have the same problem except instead of seeing the walpaper and mouse I just have a black screen. I am now convinced the problem lies in the GNOME DE
Attempts
(when I thought the problem was lightdm)
- Installation of
haveged - Disabling of the
lightdm.serviceandstartxing (however I was never able to even successfully disable the service) - Disabling of gnome extensions
- Installation/use of
gdm3
