Package: x11-xserver-utils Version: 7.7+8 Severity: normal Dear Maintainer, I used to do the following: $ xhost +si:localuser:$USER $ su - $USER and then run some GUI programs. From today I get the following error: Unable to init server: Could not connect: Connection refused Error: cannot open display: :0
AFAICT it's due to libmutter-7-0, specifically https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1424 I suspect. Presumably it previously worked using the abstract socket, but now there's only /tmp/.X11-unix/X0, which is only writable by the user running the session.
I suggest filing an issue upstream at https://gitlab.gnome.org/GNOME/mutter/-/issues .
