I am using Bullseye as updated to yesterday. It is my custom to log in to XFCE as my regular user, then "su -" in order to run as root, including GUI programs. In the process, in the past $DISPLAY has been set.
I now find on bullseye that $DISPLAY is not being set. However, even if I set DISPLAY manually or run 'su -w DISPLAY -', programs like xclock complain that they cannot open the display. How do I allow root to use the display? -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
