I've updated the description with the SRU bug template. I think this includes all the relevant info?
** Description changed: - I'm trying to run chromium installed via snap in Ubuntu 20.10 when - running Ubuntu Wayland session. Unfortunately, chromium wouldn't start: + [Impact] - > chromium + * Users who select the Wayland session on Ubuntu 20.10 cannot run snap + confined X11 applications, due to gnome-shell no longer listening on an + abstract socket for connections. + + * The fix, which has been accepted into upstream's gnome-3-38 branch + reverts the change removing the abstract socket, and fixes the bug that + prompted it's removal. + + [Test Case] + + * Start with a stock Ubuntu 20.10 desktop install. + + * At the GDM login screen, after selecting your user account use the gear + icon to select the "Ubuntu on Wayland" session, and log in. + + * Ensure Chromium is installed by running "sudo snap install chromium". + + * Try to run "chromium" from the terminal. 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.
