gdm3 doesn't have a GUI so reassigning to gnome-shell that provides all the related GUIs.

The only thing I found describing my problem was https://unix.stackexchange.com/a/39855 (passage *GUI Glitches Causing Unresponsive WM or X11/Wayland*). This is exactly my experience ("**an application stops responding and prevents you from entering input with the keyboard or mouse to other application windows**"). Specifically: - clicking on a hyperlink in (an open mail in) thunderbird freezes gdm3 at 90%. - opening files via nemo (file manager) freezes gdm3 sometimes, regardless which file type. - libreoffice freezes gdm3 a lot when switching windows via alt-tab, but not when I switch windows via super key. Whenever a freeze occurs, the clock in my taskbar stops, the mouse and keyboard still work, but no window responds. Switching to tty works. Killing the last used application (e.g. thunderbird, nemo, soffice.bin) via tty brings gdm3 to life again. The funny thing is that when e.g. I open a link via thunderbird and gdm3 freezes, then I kill thunderbird via tty and switch back to X, then thunderbird is gone but firefox has opened the link. I activated gdm3 debug output but could not find anything (I'm not an ubuntu/X/gdm expert). One freeze occurs somewhere between two **systemd-logind: got pause for 13:73** in syslog_gdm3.log ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: gdm3 3.36.3-0ubuntu0.20.04.4 ProcVersionSignature: Ubuntu 5.4.0-81.91-generic 5.4.128 Uname: Linux 5.4.0-81-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.18 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Thu Sep 2 12:23:57 2021 InstallationDate: Installed on 2018-07-26 (1134 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) ProcEnviron: LANGUAGE=de_CH:de PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=de_CH.UTF-8 SHELL=/bin/bash SourcePackage: gdm3 UpgradeStatus: Upgraded to focal on 2020-10-07 (329 days ago) mtime.conffile..etc.gdm3.custom.conf: 2021-09-02T11:47:52.516792 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1942432/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
