I did this a couple of months ago but I’ve since changed OS. I think the following worked:
sudo nano /etc/gdm3/custom.conf
Use the arrow keys to move the cursor and find the bit that says:
WaylandEnable=false
and change it to:
WaylandEnable=true
I've also done this.
I am no longer using Cosmic -- while I really liked it, it is still in alpha, and day-to-day was a bit janky in its current state. I am absolutely going to return to it once it matures.
I didn't switch OS; simply went back to pop shell / gnome (session title: "Pop on Wayland").
Hey, I ended up going a different route. I'll keep this option in mind if I need to try it later, and thanks for the help.
Thank you, I'll give that a try and get back to you.
Could I ask what you changed to and how come?
I’ve tried a few since switching from Windows. I’ve tried Fedora, Pop, EndeavourOS and openSUSE. I went back to openSUSE. I don’t know why but it just sat best with me. Fedora’s good as well but the openSUSE package manager is faster.
Honestly I think the Desktop Environment is probably more important than the distro itself. I do like GNOME because it’s slick but I prefer the layout of Plasma, even though it feels dated. There’s Budgie as well but it doesn’t feel feature-complete.
If you're logged in by default on startup, you will need to log out and select Wayland before logging in again. It won't switch you to Wayland automatically, but it will remember your last selection so you only need to choose it once.
What software are you using to watch videos?
Freetube
Steam client
I don't use Freetube, but I'm pretty sure that the Steam client can do vsync as long as you have hardware acceleration enabled in the Steam settings.
Hmm.
What video hardware are you using? Like, what's the output of this command:
$ glxinfo|grep "^OpenGL renderer string"
Do you perchance have mpv? That gives very considerable control over video output, so it's useful to try things regarding video.
Can you yt-dlp this vsync test video to your local machine? I've used it in the past to confirm whether tearing is present, and it'd be useful to run under mpv with some different settings.
I think I've found a decent solution for now, I'll keep the troubleshooting options you've listed in mind if I run into problems in the future. Thank you.
