That's what I was saying. Dolphin is getting info about partitions from udisks. Gparted is getting that info on its own. So if udisks is having problems, dolphin will have problems, but Gparted won't.

An option to hide a drive should show up when you right click on it

Ok.

My best guess is that something happened with the udisks daemon. A reboot will probably fix this. (G)parted probably doesn't use udisks, so that's why it kept working fine

Those letters and numbers are the partition UUID. Every partition has one and just used for identification.

What is the output of lsblk -f?

Edit: What distro are you using aswell?

tar: You must specify one of the '-Acdtrux', '--delete' or '--test-label' options
Try 'tar --help' or 'tar --usage' for more information.

First command fails because -name is case-sensitive

That's not how /dev/null works.

Try this:

sudo cat /dev/zero > /Windows

Hmm, I don't use a window manager so i've never used that but how are you setting GTK_USE_PORTAL=1, I have mine in /etc/environment

xdg-desktop-portal-gnome is the nautilus portal

How are you setting the enviroment variable?

Hmm, the other thing I can think of right now is have you relogged of rebooted? IIRC you need to do that for it to work.

Have you installed xdg-desktop-portal-kde?

hyfetch

There's uYouPlusExtra and YouTubeRebornPlus. I've never tried either though, so I don't know how good they are.
