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.

How to force all chromium apps to use wayland, instead of xwayland by default? (self.linux)

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=wayland

See my dotfiles on github.com/boredsquirrel/dotfiles

Same possible for Qt QT_QPA_PLATFORM=wayland

Is there a noticeable benefit to those apps running natively on Wayland vs running through xWayland?

[–] [email protected] 1 points 6 months ago (1 children)

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.

"translates it to Wayland" is not correct, XWayland is an X server that runs on Wayland, not a translation layer.

RAM: if you have no XWayland apps anymore you save RAM

True. 👍

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.

OBS on Wayland can record keystrokes too, it just that Global hotkeys can be problematic on KDE and requires a work around.

an X server that runs on Wayland

So... isnt the X window translated to a Wayland surface?

[–] Rustmilian 1 points 6 months ago* (last edited 6 months ago) (1 children)

It does not "translate" or convert X11 windows, but rather forwards them as is over wayland input devices as Wayland surfaces to the underlying Wayland compositor.
Xwayland server still runs the same code as the regular X server, but relies on the Wayland compositor for presentation and composition of the X11 windows.
"translation" suggests conversion of X11 API calls or other code, which is not happening here.

Interesting, thanks!

Yes, you get the usual Wayland benefits and tighter integration with the system. However certain applicants can be a little unstable when doing certain actions.
