org.freedesktop.Platform.GL.nvidia VS gamescope

Here the issue has been addressed bu there are some variations.

This case is a combination of an Nvidia problem and a flatpak problem. The Nvidia problem is as you stated, but there are also issues with the way Flatpak is packaging their platform packages, with multiple open bugs.

See https://github.com/flathub/org.freedesktop.Platform.GL.nvidia/issues/151

Today I installed driver 525.78.01-1 and all flatpak apps lost their hardware acceleration, steam in flatpak can't launch games because flatpak didn't updated their nvidia runtime to latest version. How I can update this runtime by hand because on their github page it shows that their commis shown latest version https://github.com/flathub/org.freedesktop.Platform.GL.nvidia.

Old driver versions should not be installed again once you remove them. What could happen is Flatpak re-installing a driver version you already have, when you run flatpak update (bug report here).

Yeah that happens sometimes when there's a build error. You can check https://github.com/flathub/org.freedesktop.Platform.GL.nvidia to see if the latest build was successful or not. Usually they're very quick to add even beta releases.

This nVidia issue also hits other projects like flatpak. They have their own solution; it might be possible for Bedrock to leverage their effort or otherwise follow their lead at some point.

Also have fun not being able to use DLSS on any of your games, because the Flatpak Nvidia drivers don't ship the required nvngx dlls.

Maybe gamesope can help? Games are nested into it to allow for better control.

Well I suppose you should start taking Wayland seriously then, because gamescope, the compositor on the Steam Deck, uses Wayland. https://github.com/Plagman/gamescope/blob/master/src/wlserver.cpp

Mini-update: I spoke with Josh (and Strudel, who referenced me to the PR), and this has been already merged into gamescope.

Valve staff is also aware they cannot force developers to retrofit 16:10 support into existing games (some do, many don't), so they even go the extra mile to provide extra functionality in gamescope to improve the 16:10 gaming experience for games that only support 16:9 natively.

I'm trying out gamescope on my laptop, and I came across ChimeraOS's fork of it. I'm not sure why I would choose one over the other. ChimeraOS mentions something about "session switch", but I'm not sure what that's about.

You can use gamescope on the desktop, I use it for a ton of games like No Man's Sky, Bethesda games, and any others that have alt tab instability.

For those that don't know (like me, three minutes ago) gamescope [1] is a Wayland compositor custom-written for games (and, I believe, what the Steam Deck uses). it's open source, and under the "BSD 2-clause" license.

I assume that this is because I'm still using ye olde steamos-compositor (https://github.com/ValveSoftware/steamos-compositor/.) I'm interested in switching to gamescope (https://github.com/Plagman/gamescope) but I'm getting the feeling it won't work on my 20.04 vintage Ubuntu; the required version of meson isn't available and I can't find a PPA that contains gamescope. My instinct act this point is to just live with the pain, as fully dealing with this will likely involve just switching all the way to Arch to more closely match the newest SteamOS and I just don't want to do that right now. Anyone know if there is a middleground that will support a modern steam big picture mode without having to totally redo everything?
