I had this issue as well, but my file system was broken when i was trashing a OS, I did not know it was xdg-desktop-portal-gtk or xdg-desktop-portal-gnome I think it was Debian with cinnamon or maybe LMDE.
I’m not blaming Arch it’s a meme, you don’t have to get mad about it.
I have broken or had the OS shit the bed with Android, DOS, Ubuntu, Fedora, Arch, Mint, SUSE, Redhat Linux, Mac OSX, IOS, and many copy’s of Windows in my years. mostly with Windows it just shits the bed, you don’t even have to try, Mac OS 7/8/9 use to love shitting the bed as well.
I use to boot to Fedora, Mint, or Windows as well, mostly as backups (I used Linux for over 20 years) but I used Arch mainly as my Gaming OS, but i did some Dev on Arch as well, Arch is good long as stuff is not broken, it use to be if you installed a lot of packages, Arch was happy to break on you, now with flatpak that is not so much the case like it use to be, Arch is getting better thanks to upstream dev’s taking away all the wiring we had to do over the years down stream.
Arch with Bcachefs and Flatpak + pipeware and KDE Wayland is looking good to me, when Bcachefs is ready maybe with Kernel 7.0? next year i may try Arch once more.
It Broke far to many times, I used Arch Linux for about 5 years or longer, systemd fixed a lot of stuff, and some of the other changes, but i needed a more production stable system.
I use ZFS Bootmenu with Debian Stable+flatpak and some backports these days and so for i only broke my system once.
Redhat does a lot of testing/patching with Xorg Server.
most of the people who was working on Xorg Server moved to Wayland a few years ago, Ubuntu and Debian have been Defaulting to Wayland, on the main Desktops, and Desktops are dropping Xorg Server support in Development, this is not just Redhat.
No Patches and No $$$,$$$,$$$ = Xorg server dead. if you want to pay 15 to 20+ Software Engineers/Testers to work on Xorg Server got for it.
FreeBSD has Wayland support to.
Even the Xorg mailing list is mostly dead, many of the Xorg Server Dev’s moved on, XWayland will be long lived.
and last i was there for all the Crying about XFree86 to I’m old.
