For a substantial amount of users Wayland is important as it has better performance and battery for integrated graphics. Having this bug unfixed and breaking graphical snaps including chromium (which does not have an apt package alternative) forces users to revert to X11/Xorg.
What is the mechanism to increase the importance of this bug and expedite the release of the fix which has been available (unreleased) for almost a month. This was a known issue on release day of Groovy. How can I help? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1897224 Title: Graphical snaps can't run in Gnome 3.38 Wayland sessions (can't open X display) Status in Mutter: Unknown Status in snapd: In Progress Status in mutter package in Ubuntu: Fix Released Status in snapd package in Ubuntu: Won't Fix Status in mutter source package in Groovy: Fix Committed Status in snapd source package in Groovy: Won't Fix Status in mutter source package in Hirsute: Fix Released Status in snapd source package in Hirsute: Won't Fix Bug description: [Impact] * 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: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1508 [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. 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.
