Guest user account not retaining any changes after reboot

I liked the idea of guest user account where I can lend my device to some friend or family without revealing my admin password.

It however comes with the default garuda configurations. I'd like to change some stuff like display scaling and icons. I tried it, but the settings revert to default after a reboot. I can't even have scaling changed without reboot.

How about another user (family) and without root rights and password?

I think you will find solutions in the arch wiki.

i killed the guest by removing it :wink:

I've never tried it, but I might want to make my changes in Guest then switch user (log in, no re-booting) to a root account, set them, and see if they stuck.

Like said; I've never tried that. Shouldn't cause any harm (he said, with fingers crossed).
:wink:

The whole point of the guest account is that changes are not saved. It's like booting off a live image, except with the software you already have installed on the root filesystem. @SGS's solution is very practical I think

Is the "guest" account completely different from what I would create using say the add user GUI or useradd?

I assumed it to be the same thing.

Yes, for example

passwd guest
passwd: You may not view or modify password information for guest.

Edit: my bad, it appears as root you could set a password for guest :eyes:
Instead of modifying anything about that account, I would simply hide it by adding it to the line

HideUsers=guest

in /etc/sddm.conf

I see. I was under the impression that it's just a non-admin account created by default as per garuda custom configs.

I'll try adding a new user account, and probably remove guest account.

Thanks

That is the very purpose of the guest account. The guest user is using the computer on a temporary basis. Once she leaves, all the customization is reset. That is basically the expected behavior for the guest account.
