xhost-command in Debian11

[BerndSchmittNews <Bernd.Schmitt.News@gmx.net>]

Hello.

I used to use xhost-command and su -l ... -c ... to run programs as a
different user in debian10. In debian11 I get an error about having no
DISPLAY env variable specified.

Does xhost work different now?



$ uname -a
Linux VB-Deb400 4.19.0-16-amd64 #1 SMP Debian 4.19.181-1 (2021-03-19)
x86_64 GNU/Linux
$ xhost local:
non-network local connections being added to access control list
$ su -l notserious -c firefox
Passwort:
Error: no DISPLAY environment variable specified

Thx
