I think a better way for the other user to have stated this, is learning Linux, while difficult at times, should be a fun and rewarding experience. I’m about a year in, and this is all easy stuff to me. One year ago? I would have been as frustrated as you are. But I persevered, I learned, and I got a sense of accomplishment out of becoming competent. I don’t really need to ask too many questions now, because the more I figure things out, the easier it gets to figure things out.
If you’re not into that, Linux might not be for you. But I hope it is, I hope you persevere and keep learning and find the same satisfaction from it that I have.
Here’s another vote for EndeavourOS if you need it. I run BTRFS and timeshift-autosnap, but I’ve never needed to use it. Like the other poster said, I’ve had minor annoyances and brief package conflicts, but nothing critical has ever gone awry.
You could give this a try instead. It’s a reverse engineered iCue driver which probably supports your keyboard and any other Corsair peripherals you may have.
I love Linux Mint, and always used cinnamon. I Loath the gnome experience, and XFCE has always struck me as too old feeling and sparse. Currently I use EndeavourOS with KDE Plasma and I couldn’t be happier.
If you’d like to try out KDE but don’t want to move away from a more stable experience to an Arch based distro, I can recommend MX Linux. It’s based on Debian stable instead of Ubuntu, and has a KDE plasma spin.
Well, that’s unfortunate. I have all razer peripherals that work great with openrazer for a back end and polychromatic for a gui front end. I don’t have any corsair devices anymore so I can be much help. Good luck.
