Does anyone run Emacs with wsl2? I've noticed that fonts are quite a bit less crisp than they could be. On the left is running Emacs on a native terminal, on the right is the gui application. (alien.top)

You can try emacs-pgtk package, cause WSLg relies on Wayland

Yep that's what finally caused me to switch to using Emacs on WSL2 (instead of the Windows build). Then you can also get rid of that ugly white border from WSLg.

any details on that white border stuff? pgtk didnt autofix it for me in the past and id love to not have it searing my eyes

[–] filippoargiolas@alien.top 1 points 10 months ago

that sometimes happens when wslg has issues with bind mounting the runtime dir from the system distro or runtime dir permissions, were you by chance using it with a uid != 1000?

[–] teaspoonzzz@alien.top 1 points 10 months ago

Not sure if there's something else missing in your setup. I'm using WSL2 (Ubuntu), and in my case all I had to do was compile Emacs passing the --with-pgtk flag, then:

sudo apt install gnome-tweaks yaru-theme-gtk yaru-theme-icons

And ran gnome-tweaks in the terminal, and changed the application and icon themes to Yaru-dark.

I downloaded the source code for emacs and compiling it locally with the --with-pgtk flag. (And --with-native-compilation for better performance)

That made my life improve a lot.

You can also install pgtk emacs directly from snaps when under Ubuntu in wsl, if you prefer.

I get a warning when compiling emacs from source with the pgtk flag telling me about a known bug in my version of gtk that causes problems when opening and closing multiple emacs instances. Do you know anything about this? In particular would it be resolved by switching to the snap?

[–] glgmacs@alien.top 1 points 10 months ago

I have no idea about that compilation issue you get. Since the emacs snaps (pgtk and x) are pre built binaries, you wont get that problem. Ive been using Emacs PGTK from snaps on WSLg for a year without any issue.
