XFCE4 screen resolution problem when switching user
Hello,
My screen resolution is : 1920x1080 on Xubuntu 20.10, XFCE 4.14.
It is ok for the first user logged in. When I switch user, the login screen resolution is 640x480 and it is the same with the second user logged in. If I log out instead of switching user, it is ok! In xfce4-display-settings I can see :
- First logged in user : LG screen 27" / Complete list of screen resolutions available with this monitor
- Second logged in user : default / 640x480 only
It seems that the first user locks something in the display settings that affects global access to display.
When I switch back to the first user, in Chrome browser texts are not shown any more, I have to close and reopen browser so the display is ok again.
I don't know if it is the right place to post my issue. I have this problem for several years I think. Maybe something is not well installed? Corrupted? Do you have an idea where I can search what is broken?
Thank you in advance for your help.
