<html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> </head> <body> Hello, Environment: Debian bullseye (custom build using debootstrap), Kernel 5.10.52, Weston 9.0.0-1, systemd 247.3-7+deb11u1. I am struggling to get weston running as a user. It is working on some other Debian bullseye BSP image, but not in my Debian image (both are very similar). When I use weston-launch in a systemd service and add a "--user" and "--tty" (see service below), I always get the following error: ########## Feb 17 12:16:24 tavla systemd[1]: Starting DISPLAY Wayland Service...
