The bug affects me, too. I just installed the three above mentioned mutter packages (libmutter-7-0 mutter mutter-common) and now Chromium is working again. Thanks for the fix!

Without the fix, it will fail with the error "Unable to open X display". With the fix applied, it will launch as normal. [Regression Potential] * The patch modifies the logic gnome-shell uses to launch Xwayland. So there is a potential that the change could break X11 application support on the Wayland session. * The default configuration for gnome-shell is to launch Xwayland on session start, so it should be immediately obvious if there are problems. * In addition to checking snapped X11 apps like Chromium, verify that a few classic X11 apps still launch correctly (e.g. xterm, xeyes, etc). [Other Info] * Running "ss -xlp | grep Xwayland" should show that it is listening on both "/tmp/.X11-unix/X0" (the regular unix domain socket) and "@/tmp/.X11-unix/X0" (the abstract socket). --- I'm trying to run chromium installed via snap in Ubuntu 20.10 when running Ubuntu Wayland session. Unfortunately, chromium wouldn't start: > chromium [49244:49244:0925/094607.732169:ERROR:browser_main_loop.cc(1417)] Unable to open X display. I am able to run Firefox just fine (assuming that Firefox still runs on xwayland) and also Intellij snap works fine.
