Thanks Daniel, the core file I got from the crash (in my home dir) shows as
core: ELF 64-bit LSB core file x86-64, version 1 (SYSV), SVR4-style, from '/usr/bin/Xwayland :0 -rootless -terminate -accessx -core -listen 4 -listen 5 -d', real uid: 1000, effective uid: 1000, real gid: 1000, effective gid: 1000, execfn: '/usr/bin/Xwayland', platform: 'x86_64' If I try to run "ubuntu-bug core" on it, I get a dialog saying that the problem cannot be reported because the core is about a snap published by Canonical. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1769981 Title: Temporary screen freeze when coming back from screen standby To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1769981/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
