Bug ID: 512844
Summary: Ability to manually scale entire screen on Wayland,
like xrandr --scale
Classification: Plasma
Product: kwin
Version First unspecified
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: wayland-generic

Target Milestone: ---
SUMMARY
On X11, you can scale your entire screen by doing `xrandr --output Whatever
--scale NxN`. For instance, 2x2 gives you 2x SSAA, and 0.5x0.5 with --filter
nearest (...I think? it's been a while) lets you do integer scaling, e.g. 1080p
to a 4K screen with no upscale blurring (like the screen itself would do if you
sent it a 1080p signal).
In addition to just being useful if you want to run your desktop at 1080p on a
4K TV or make games run better/get SSAA by pretending you have a smaller/bigger
screen (gamescope can handle game usage pretty well honestly), pretending you
have a bigger screen than you've got can also be helpful for taking screenshots
of really big things like long comment threads that don't fit on your screen.
It's also great if you've got a 640x480 monitor (our CRT can get 120Hz if we
push it that low) and want to run a 1280x960 desktop! The display scaling
doesn't go _below_ 1.
STEPS TO REPRODUCE
1. Attempt to scale screen.
OBSERVED RESULT
There's no way to scale the entire display output, between rendering the
desktop and outputting it to the display. (Unless I'm mistaken and this is
already implemented.)
EXPECTED RESULT
There's some way of doing scaling, whether that be a setting or a terminal
command (even just a terminal command would give us parity with X11).
SOFTWARE/OS VERSIONS
Operating System: Debian GNU/Linux 13 (actually forky/testing, not trixie)
KDE Plasma Version: 6.5.3
KDE Frameworks Version: 6.20.0
Qt Version: 6.9.2
Kernel Version: 6.17.8+deb14-amd64 (64-bit)
Graphics Platform: X11
Processors: 12 × AMD Ryzen 5 3600 6-Core Processor
Memory: 16 GiB of RAM (15.5 GiB usable)
Graphics Processor: AMD Radeon RX 6600
ADDITIONAL INFORMATION
On X11, I think this is actually a subset of a general display transform
mechanic. That's a pretty cool feature to have, and it would be cool if KWin
implemented it, but it also might be overkill!
