External display

Desktop Mode
- Fixed a case where the desktop could be empty and apps would fail to launch.
- Fixed a bug where switching to the Plasma Desktop transition could result in broken colors.
I love that they’re driving HDR. ChimeraOS has already pulled it in, the first desktop distro to support it. I think I may finally be ready to drop my last windows box with this
Agreed. Windows 10 getting end of supported in 2025, and HDR and gaming on Linux finally a thing, I’ll no longer be dual booting.
Probably a stupid question… Is HDR only when hooked up to a monitor? The Steam Deck screen isn’t HDR capable right?
Correct, it doesn’t support HDR or VRR for that matter
Love that they fixed the broken colors in desktop mode. It’s annoying when setting up emulators.
But i still have the charging light issue that should have been fixed in firmware 116 :(
