yeah I'm also quite a noob with linux I've only been using it for about a year and also dual boot my pc for the few games I have to for me it's actually bethesda games mostly due to no mod managers on linux and I know there's the workaround for MO2 which is what I use anyway but fomods didn't work :/ I'm also actually playing through hollow knight on my deck at the moment though vanilla and that's been working flawlessly as for curseforge dunno what you're modding but if it's mc I used prism launcher and that worked flawlessly way better than curseforge on even windows with that being full of bloat

As Phuntis said, curseforge is easily solved with prism launcher. They have a nice GUI to browse modpacks and set up everything automatically. For mods that don't allow direct downloads over the API, they give you a browser link you can open and automatically pull the downloaded files from your download folder.

The launcher also has integration into modrinth and a bunch of other useful features. IMO the better launcher compared to the official one, even if you don't play modded.
