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.

You can right now. If you are using KDE, it should work with mpv, though you might need to launch it from terminal with a few flags to tell mpv to use HDR.
If you’re not using KDE, you can launch gamescope with the hdr flag in the tty and have it launch mpv.
Though I’m not sure any browsers have working HDR. I think Chromium may have some stuff in progress. Gnome Web may get it since WebKit supports HDR and HDR is being worked on for GTK.
gnome iirc also has merged the wip protocol so it should work on gnome too
It’s hidden away on Gnome. You need to hit a keyboard shortcut that brings up a special console window then run a command to enable the HDR.
For better or worse, Plasma has the option prominently displayed in settings.
Do I have to enable HDR in Plasma settings? Because when I do, and then log out, plasma crashes and I have to log into a different DE and disable HDR in the terminal.
