Thanks. It looks like the nautilus process isn't frozen at all: https://errors.ubuntu.com/bucket/?id=/usr/bin/nautilus%3A6%3A__GI___poll%3Ag_main_context_poll_unlocked%3Ag_main_context_iterate_unlocked%3Ag_main_context_iteration%3Ag_application_run
Which makes sense because a properly frozen process wouldn't respond to being asked to close. And so I suspect it has found a way to partly freeze the compositor, maybe. The only remaining ideas I have are: * Try scale 100% to see if it avoids the bug (not for your own sake, but for our information). * Try disabling fractional scaling briefly, for the same reason. * Try a different Nvidia driver version in the 'Additional Drivers' app. * Try Wayland. * If I get time in the coming weeks I may try to build a system with a similar configuration and try it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2058327 Title: Starting up Files app in external monitor freeze the entire monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/2058327/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
