I run a plasma wayland desktop which is started from VT1 with dbus-run-session -- startplasma-wayland I have a dedicated user for steam games. Previously I could run X11 apps as this user within the main wayland display. But after recently updating kde-plasma/ packages (kwin, plasma-workspace, etc.) to 5.22.5 this now fails to share the display. $ xhost +SI:localuser:steam localuser:steam being added to access control list $ sudo -u steam glxinfo Password: Error: unable to open display :0 ---------------- I tried setting various environment variables like DISPLAY WAYLAND_DISPLAY XAUTHORITY XDG_RUNTIME_DIR. I tried tweaking the runtime dir permissions. chmod -R go+rw /run/user/1000 # insecure - don't actually do this Also tried adding pam_xauth module. echo "session optional pam_xauth.so" >> /etc/pam.d/sudo But none of this helped. ---------------- As a workaround I can switch to VT2 and start a separate wayland display as the other user. Reproducible: Always Steps to Reproduce: dbus-run-session -- startplasma-wayland xhost +SI:localuser:steam sudo -u steam glxinfo Actual Results: Error: unable to open display :0 Expected Results: normal output of glxinfo Portage 3.0.20 (python 3.9.6-final-0, default/linux/amd64/17.1/desktop/plasma/systemd, gcc-10.3.0, glibc-2.33-r1, 5.10.61-gentoo x86_64)

Nice! The patch also applies successfully to kwin-5.22.5 if you remove lib/ from the path.
