OK, I'm totally sure it's a freeze. Moreover, gnome-shell stack trace looks normal, event loop runs just fine. I can generate and provide core file if needed.
What I managed to debug so far, is that in case of multiple /dev/dri/cardX being created frame_cb in meta-stage-x11.c:296 is not called which simply results in the screen being stalled. Debugging it up the stack trace leads to conclusion, that cogl_glib_source_dispatch in cogl-glib-source.c:133 is not called at all for some reason. Natural assumption would be to track that function down, unless there's sth more you can recommend me? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873401 Title: xorg lock-up on GPU hotplug To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1873401/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
