Nope. I was actually able to get it working the other day after ditching flatpak and re-installing Steam, Gamescope, and MangoHUD with DNF instead. All the guides I read said that flatpak would be no issue, but it was clear that as soon as I referenced any of the above applications in the launch arguments it would fail to load because it didn’t understand what I was asking to launch.

So, all in all, I now have Rocket League running at a high framerate with FSR on integrated graphics. It only took two days :P

Yes I am. I appreciate the help though. It seems pretty clear that it’s failing to recognize the gamescope argument because even if I use it barebones without any resolutions or FSR arguments it still fails to launch. Wish I could see thr output somewhere so I could know what to look into.

That said, I have since looked into Nobara and Bazzite and they look really promising. They should have all this stuff I’m trying to do baked right in. The point still stands though that these are extra complications that I wouldn’t have on Windows with a full driver suite.

Like you I’ve tried to game on Linux and each time have had to go back. I really want it to work, and to be fair, it DOES work. I love my Steam Deck and it’s proof that with enough tuning you can get a good experience.

However if you want to get more than a game just running, that’s when you have some issues. Like you I had the X11 multiple monitor issue people describe. Wayland is the fix these days but there were still issues using both different high refresh and VRR at the same time (may be fixed now).

My current issue is trying to get gamescope running when launching games from steam on Fedora 40. I have the flatpak of each and guides say it should just work, but every time I use gamescope as a launch option nothing launches. I imagine there must be a log somewhere but I don’t know where that is. I found some open bug reports that say gamescope just broke a few versions ago with Steam, who knows.

The only reason I need to use gamescope is that there is no AMD control panel, so no way to get FSR. This is a lower end GPU and I really need FSR for this particular game to run well. This is the biggest issue IMO, with only basic GPU drivers the community has to figure out how to implement the latest gaming features on their own, which means it is years behind. The VRR/High Refresh multiple monitor issue for example is something windows was doing with ease several years ago and Linux is getting it now.

So you have to give up a lot of multiplayer games, and you have to be OK with just running the game, not anything modern like DLSS or frame gen, or whatever is cutting edge. For this reason I can still only recommend gaming on Linux if you’re on a Steam Deck, or if you’re a techy person who mostly plays single player titles. Anything more and you will be messing around more than playing.

I don’t see the Deck as a critical mass device, and if Valve choses to make it one I will probably no longer be interested. The Deck is great because you can tinker to your heart’s content in an open system. That just isn’t going to fly if Valve decides they want to be the next Xbox or Switch.

Everyone is losing their shirt over ARM because Apple is producing some insanely expensive chips on it that have high performance. I’m not saying ARM doesn’t have some advantages, but I think that’s a long way out from going into something like the Deck where compatibility is everything. The switch being ARM has nothing at all to do with this conversation.

The whole point of the Steam Deck for me is playing my older games. Unless they get x86 translation working without a performance hit them I’d rather they stay on x86.

That’s a good point. I’ve never participated in that so it didn’t really factor into my opinion of them. In every way I’ve interacted with the company they have been excellent.

I like them because they make niche products that may not have mainstream appeal, but that their customers love (steam link, steam controller, valve index, steam deck). They have excellent customer support and always do more than they have to:

• My GF lost the power adapter to her steam link and asked how to buy a new one, they just sent her an entire replacement device since they were stopping production anyway
• One of my Index lighthouses died and I had bought it used from a guy since they didn’t sell them in my country yet. No questions, they sent me a new one
• When they were releasing Half Life Alex they just checked if you’d ever had an index connected to your PC and if so they gave you a copy. No asking for proof of purchase or redeeming codes that expire.

I could go on, but yeah to me they are pushing Linux forward, making hardware that excites me, have reasonable prices, and great service. So I like them.

You are technically correct, but Valve is a very “consumer first” company. This of course is no guarantee they’ll always be “good”, but Valve has earned and maintained my trust over the years and I trust them more than any other company I can think of. Far and away orders of magnitude more than Microsoft.

How would you change his setup to prevent ARP attacks? More network segmentation (clients and servers on separate VLANs) or does OPNsense additional protections I should look into?
