Unable to unlock OS
I'm following a reddit thread on fixing bad performance on Marvel Rivals, and one of the steps of the suggested fix is to install game mode, however gamemode needs to be able to write to its config, which it can't do until I give permissions. But whe trying to unlock the OS to edit the permissions on this file, I keep getting read-only filesystem errors. How can I change the permissions on this file in /usr/share/?
