Updates taking that much space is a bit surprising. I used to run linux mint on a 20 gb partition and usually had 3-4 gb space free. Does Linux mint comes pre-installed with flatpaks (you check with flatpak list)?
But 20 gb is on the very low side, you will run into issues on updates. You probably need to extend the linux partition by at least 10 gb.
For the printer issue, check the status of the cups service (sudo systemctl status cups).
Currently most cooperate linux companies are not in the business of selling linux desktop itself. Rather its linux for servers, administration, embedded things (like cars), and other enterprisey stuff. So at least at the moment they are not looking to profit of linux desktop users directly which has saved us from enshittiffication attempts.
But even if they in the future attempt to do something fishy, that most users dont agree with, I think by the virtue of how stuff works on linux it will be very easy for people to move to something else or a fork, and still get 95-99% of the same experience. This in turn will force companies to think twice before doing something like this.
A good example here is canonical/Ubuntu who has made questionable decisions in the past and each time they had to take it back. Even now, Snap due to its use of a centralized store is almost universally shunned by the linux community and is only supported maintained by canonical. While Flatpak is supported by the wider linux community with people from different projects contributing to it (though I sometimes worry about everyone centralizing on Flathub to the point where they are actively discourage other projects from launching/maintaining their own stores/repos).
This is why we need to build and champion tech that is resistant to control and enshittiffication. Then we dont have to worry too much about who is developing it.
which gen is your igpu? Older intel igpus need libva-intel-driver pkg installed (on Arch, not sure whats the Fedora equivalent) and the env variable LIBVA_DRIVER_NAME set to i965.
Also, related note, how easy is it to migrate from one distro to another? I am thinking about trying something else - maybe base Fedora or Arch - to hopefully have better performance.
You can backup your data and restore but will have to reinstall all your apps.
Also have you tried asking in the nobara discord? GE and other devs are in there so you likely to get help there.
yes I think you can since gimp 3.0
