I use kvm switch and run into this issue.

I am currently on Fedora 41, Gnome. I’ve seen this issue when running Arch on the same hardware without kvm switch to the point that I disabled suspend.

The fix for me is Ctrl-Alt-F1. It simply brings display manager’s login screen. Gnome on Fedora 41 uses gdm.

The rationale here is simple: the display manager should be resetting screen to display login screen.

I switched to XFS.

The most important feature to me is support for file deduction which is supported by XFS through reflink. BTRFS supports reflinks as well.

Snapshot in BTRFS seems like the most desirable feature, but in real life I ended up not using it.

I usually prefer drive mirror setup, but it can give its own headaches.

These days I simply have 2 disks and nightly rsync job copies content of one drive to another. This protects from drive failure.

Rclone job sends most important data to offsite backup.

The biggest loss is missing data checksums, but it is a unique feature of BTRFS that most filesystems manage without.

I don’t have setup to expand partition beyond one drive. It comes with its own headache. I simply use large enough disks.

He was running long installation process from command line and lock warning was probably appropriate.

He was probably supposed to mark downloaded .run file executable. Instead he went to collect errors.
