Symptom
the GUI screen goes blank black soon after login and return to login screen
Suggestion
Before blindly trying solutions on Internet, check the error log for hint first
The log for desktop GUI can be observed in .xsession-errors
Possible fix
# For setting error
rm .Xauthority
# For privilege error
sudo chown -R $USER:$USER ~
# For user configuration error
mv ~/.config/dconf/user ~/.config/dconf/user.old
