From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

By going back in time to a version that you know worked.
If that doesn't fix it, then you can be sure the problem is hardware related, because it still happens on the exact same software that used to work.
And if it does work on older software, then you can go forward one update/snapshot at a time, until you find the change that causes the problem.
Different distros still run the same software. Gamescope isn't going to be different on Cachy vs Bazzite. Why would it be?
What you need to do is compare different points in TIME (older versions), not the same software just installed differently.
It also doesn't happen on different software, which suggests it's not a hardware issue.
I don't have the slightest clue how to do anything with snapshots and it's been months since it began anyway so I wouldn't even know where to start. And even if I did know which version caused the problem, I wouldn't know where to go from there.
Well, if you didn't create any, you can't go back to them.
My suggestion is to find the archival ISOs of older versions and try them WITHOUT updating after installing them offline.
Though, if you end up having to install gamescope from the internet, then you're likely getting the exact same latest version no matter what distro you use.
Hence, maybe just easier to learn how to install older versions of packages on cachy. The Arch archive repo makes that quite doable.
You pin the package/system and prevent it from updating so it keeps working for you. And report the bug so it can be fixed.
A different distro is not different software.
Gamescope on Bazzite is the same as Gamescope on Cachy. Same for Plasma/KDE.
Why would they be different?
...what!? LOL
Gamescope on either is also not the same as Plasma.
Yes.
A distro or distribution is just a collection of software packages, and usually a package manager.
The actual software itself is the same. The list can be different, but where the items overlap, they are the same. How up to date they are can vary, but Plasma 6 on Bazzite is the exact same as Plasma 6 on Cachy.
Systemd is the same systemd across arch, ubuntu, mint, endeavour, fedora, and any others that use it.
Is this not obvius?
Changing the distro does not tell you much. Especially as you're running the exact same program in the exact same DE, you should absolutely expect the same result.
Not only is it not obvious, it's not accurate.
Software packages that are different . That's what makes one distro different from another. Is that not obvious?
No? The same software is the same software, regardless what distro you install it on.
Gamescope running on top of KDE/Plasma in one distro will not be different from Gamescope running on top of KDE/Plasma in another distro.
Distros are just presets. They have far more similarities than differences.
What makes one distro different from another, is that it might come with gnome instead of KDE, pacman instead of apt, initd instead of systemd, systemd-boot instead of grub.
Or any other litany of alternative packages that do the same thing.
But you use the same spftware, the there is little difference between one distro and the next. The main difference is going to be that you installed the same code from a different distributor.
That's literally where the name "distro" comes from.
So...different software? Those are all software.
The name comes from different distributions of Linux that come packaged with different software .
I don't know what semantics game you're trying to play here or how it's supposed to help me fix my machine but I'm out.
No.
We use the word distro because they're not really a fully separate OS. Just a different preset with either a lot or almost nothing swapped out as compared to the next.
You are so hung up being correct here you're missing what I'm actually trying to teach you.
You need to be comparing different versions, not distros. Because the same version of the same software is going to have the same problem, no matter what distro you use.
You don't even know how to access system logs, and you expect to understand enough about this stuff to successfully correct me on why trying a different distro isn't that helpful for troubleshooting?
I'm not missing anything. What you're missing is that there are 2 different graphical compositors (AKA software). One works, and one doesn't. On the same hardware. So it's not a hardware issue.
AND I AM TELLING YOU TO DOWNGRADE THEM SO YOU CAN SEE IF AN EARLIER VERSION WORKS CORRECTLY, INSTEAD OF SWAPPING OUT THE ENTIRE DISTRO
ONLY TO TRY THE EXACT SAME COMPOSITOR AS IF THAT WOULD FIX IT
So instead of that, try earlier versions! Different distros from the same date are obviously likely to be running similar versions of Gamescope or whatever else might be the cause.
