How to force all chromium apps to use wayland, instead of xwayland by default?
I am aware of the switches you can pass to each app to make it use native wayland, but is there any way to do it globally?
You mean Electron?
The Arch wiki has docs about that.
For Flatpaks I use the environment variable
ELECTRON_OZONE_PLATFORM_HINT=waylandSee my dotfiles on github.com/boredsquirrel/dotfiles
Same possible for Qt
QT_QPA_PLATFORM=waylandIs there a noticeable benefit to those apps running natively on Wayland vs running through xWayland?
I have not checked this, but as far as I know
- performance: apps are running on a subset of XOrg and xWayland translates it to Wayland
- RAM: if you have no XWayland apps anymore you save RAM
- features: some apps may have more features on XOrg, some may have more on Wayland. OBS on XWayland can record keystrokes, QGis on XWayland has not broken dockable toolbars.
Depends on your distribution. Arch packages some electron apps in a way, where they can accept their own flags through a dedicated file. For others, it’s just a plain
electron-flags.confin your~/.configI would recommend visiting either the arch wiki, or tour distributions equivalent for details
Keep in mind that this does not apply to CEF apps, as that’s an entirely different framework
Probably not directly helpful, but Nix packages for Chromium and Electron apps are set up so that you can switch to native Wayland mode globally by setting an environment variable,
NIXOS_OZONE_WL=1I don't know of any global setting that isn't distro-specific.
For electron, if
ELECTRON_OZONE_PLATFORM_HINTandelectron-flags.confdon't work, you can also add--ozone-platform-hint=waylandto the end ofExecin each .desktop file (also works on Chromium,but not CEF AFAIKand sometimes CEF).There's also
--ozone-platform-hint=autoif you find yourself switching between X11 and Wayland.Spotify is CEF, I think, and it works pretty well.
Do you mean Electron apps? I didn't even know you could force them to use Wayland.
Is it bad if they use xwayland?
They are kinda choppy, when compared to native Wayland apps and screensharing from an app, running in xwayland doesn't really work...
Bad is relative. But I have some problems with scaling on a HiDPI display with some Electron apps. I think that might be solved if they were Wayland native.
Define bad.
If you can run native in wayland, run in native wayland. Your performance will be better, and if you need scaling, scaling is considerably better too
Like X11, xwayland is not as secure as a pure Wayland environment but I think it's important to note that hundreds of thousands of desktop Linux users are likely still running X11.
So, in my opinion, it is not ideal to run xwayland but still completely acceptable for most users who don't have special security requirements.
If you need fractional scaling, they are unusable blurry. Some screens just need fractional scaling so for those setups it's almost essential to do this.
You need fractional scaling it your resolution is very high compared to the screen size. So something like a 15 inch 1440p screen would need 150% or 125% scaling because 100% is too small, 200% is too large but with anything in between, xwayland apps are blurry af.
