Merging can only happen once a real world userspace application has
implemented support for it. I'll try to do that sometime next week in
KWin
Here's the promised implementation:

Thanks!
In testing with the patches on top of kernel 6.9.6, setting the
property to `Require color accuracy` makes the sysfs file correctly
report "Device or resource busy" when trying to change the power
saving level, but setting the property to zero doesn't really work.
Once KWin sets the property to zero, changing the power saving level
"works" but the screen blanks for a moment (might just be a single
frame) and reading from the file returns zero again, with the visuals
and backlight level unchanged as well.
Hmm I'm a bit surprised the IGT tests I did didn't catch this.
Are you working on a system with two GPUs by chance (like a Framework
16)? If so; can you try the "other GPU"?
As it seems your PR to span 3 projects and I've never built KDE before
can you spit out some artifacts somewhere that I can have a play with to
reproduce your result and find the kernel issue? Arch pkgs would be
preferable for me, but some RPMs or DEBs are fine too.
