tip: don't install fish or whatever, change your default shell, THEN uninstall fish because you don't like it.

Change your default shell back first.

I have seen way too many support posts where people paint their self I to a corner doing that.

or just don't change the default shell.

run fish as needed, then exit back to bash when done.

I have

I am reminded of the ability MANY years ago to write the kernel file directly to a floppy disk, or start of a hard drive and somehow being able to boot that way.

I just can't recall how I did it, or WHY I did it.

Back when the kernel would fit on a floppy disk. I am truly showing my age.

6 yr old grandson found a box of old floppy disks and was asking what they were. He started stacking them up making card houses and roads for his matchbox cars. Glad he got some use out of those recycled AOL floppies.

I have seen this used in school situations with 3+ seats per PC.

that can add up when dealing with a dozen+ PCs.

For home use, not much a benefit, but I did have it setup years ago for the grandkids.

And does uninstalling a flatpak app also uninstall flatpak dependencies that came with it?

from what I have seen, NO it does not do so automatically. there is a flatpak command option to clean out unused runtimes, and another to remove user data.

delete app data after uninstalling?

you either manually delete the data, or there's some flatpak command option, or you can use a tool such as warehouse which is available as a flatpak.

other posts list the specific commands.

check to see howuch space your log files are using.

to prevent it from happening ..

I would consider 20GB for / to be too small for long term desktop use.

and with just 470GB for /home, I would not split the two up.

It's going to depend on what desktop environment you are using, the default Gnome launcher has a huge full screen launcher setup.

there may be gnome extensions for another look.

Gnome is not the same look, but similar in its oversized UI.

I hate it.:)

I tend to use some other quick launchers. or a simple nested applications menu.

you mean like the various CAD software that exists?

what tool to use can depend on what you are drawing.

Been playing with that Bazannite (sp?) Variant, it works fine, but i am still undecided if learning the ins and puts of it are worth the switch from my Pop_os install.

There was a little bit research and learning to do some tasks, but nothing surprising.

it does seem it boots much slower than my pop_os install, but I think I have it installed on an internal Hybrid HDD that i not yet replaced with a SSD, so that may be the cause.

pop_os boots amazingly fast, not sure what they do to it.

and having to reboot to get stuff updated/installed is a bit annoying, the ability to roll back is the trade off I guess.

However I can't really think of a time that I needed to roll back, perhaps I am just lucky. So the entire roll back feature is something that I don't know if I will ever actually use.

good luck.

I thought KDE was working on some cross platform programs, but I can't recall the name of the project or the tools, they had a file manager, and a few other things. I thought it included a basic terminal emulator.

I may be thinking of the following project.

https://mauikit.org/apps/

it shows screen shots for 'station' on mobile, but I can't find a .APK for it.

ProtonVPN supports the OpenVPN client , so you can import your proton VPN settings in to that, no need for the official proton VPN GUI client.

However you do lose some of the more advanced features of proton VPN.

for testing, and no, no issues at all with the various dot files.

Cluttered app menus, and an occasional "default open with app" setting changed is about the only issues.

I have 5+ DEs on my pop_os install, you don't lose files in your users home.
