Redshift not working In KDE Plasma

Axios

Citfta Ah no problem.

TraceyC

Citfta From what I see there it looks to me like I AM using Wayland. Am I understanding that correctly?

Yes, you're right. Thanks for filing the issue (here's a link to it. Based on the output in the bug report, this may not be a packaging issue after all. I thought this might be a problem with Geoclue but I see it's getting your location (you did say that). It gets mine as well. We'll diagnose the problem more in the bug report (I asked for some information there).

Note that redshift hasn't seen a release since 2018. If the problem is because things have changed in Wayland, and redshift needs to change, that probably isn't going to happen. In case we aren't able to resolve this, you might look into alternatives.

I assume Redshift simply doesn't support Wayland.

Citfta

Since it appears Redshift does not work on Wayland I have been looking for an alternative. Most of them only adjust the color or britghtness and not the gamma. I have found a couple that are for Wayland and do adjust the gamma but they say they are for Wayland compositors supporting wlr-gamma-control. I don't know what that means. Do all Wayland compositors support wlr-gamma-control? Or does anyone know if Wayland on Solus has that?

I really appreciate all the help and suggestions I have gotten in this thread. Thanks to all.

As @EbonJaeger mentioned in your issue, check out gammastep. It looks like a drop-in replacement of redshift for wayland.

CorvusRuber

Just for info, Plasma has a built in Night Light feature that more or less replicates the functionality of redshift.

Citfta

CorvusRuber I have been using Night Light as I mentioned in my first post. Night Light does not give you any adjustment for gamma.

I just wanna say when I first posted didnt realize this type of program would not carry over to wayland
but it dawned on me shortly afterwards.
Lots of great input on the subject.

me either. I don't automatically assume wayland is as restrictive as it is but I'll have to change my thinking.

Citfta

I have tried to install Gammastep using this command that is supposed to be for Solus:
＄ sudo eopkg install gammastep
This came back with a few lines that each said success. Did not show any problems.

When I searched the menu I found "Run Gammastep". When I ckicked on that I got the same results as with Redshift. Mouse curser changes to icon and icon shows up on the task bar. Then both disappear after a few seconds and normal mouse curser comes back.

Trying again in Konsole I got this:
carrollb@carroll-solus ~ $ gammastep
Error: Could not control gamma, exiting.
Error: Failed to start adjustment method: wayland

So it looks like Gammastep also doesn't like Wayland or vice versa.

I am learning alot on this little venture

Axios I am learning alot on this little venture

I've been learning a lot today too about it since you mentioned it this morning. Supposedly XWayland in an X11 environment can bridge the gap but not for every app.

I see a list of many apps that can't run in Wayland without modification/tweaking including many flatpaks (which is a mesa in freedesktop issue).

While I personally have no problem making do with another app if it has to be that way, many do not roll like this.
At the end of the day, the Gammastep people offer a common blurb I've seen with other disclaimers: mutter-based stuff is a challenge. And the wayland compositor continues to evolve. When that is dialed in, look out.

Citfta

As you both have said I also am learning a lot. But so far none of it has been helpful except now I know several ways that don't work to get gamma control. Just like Night Light there are several other apps that let you control the color temperature. And that does help to reduce eye strain. And if you are using a desktop PC then most likely your monitor has a contrast control like the older TVs used to have. But as far as I know there aren't any contrast controls on laptops, only brightness. Redshift that worked well in the past did have a gamma ccontrol which appeared to work the same as a contrast control on a monitor or TV.

I appreciate all the help and I will keep digging too to see if I can find a gamma control that will work with Wayland.

A quick question. Is it possible to switch to xorg and still keep plasma? I do really like Plasma but was okay in the past with other DEs.

Choose x11 on sddm login screen instead of Wayland. That's it

brent

Citfta as someone who is looking at cataract surgery in one eye maybe end of year...is it possible the needs of your eyes may change as they heal? i.e. less emphasis on gamma and more on overall program dimness and warm tones?

TraceyC

This is the easiest workaround for now.

Thinking about this more, the KDE folks are interested in making Plasma more accessible. I went looking on the bug tracker and found this feature request. I've added a not about your use case. Feel free to cc yourself on the feature request if you want updates.

Citfta

Thank you Traceyc for adding that note to the feature request. I really do appreciate all the efforts of everyone on this forum trying to help me.

I did log out and back in to x11. However neither Gammastep or Redshift worked in x11. And when I tried Waydroid it no longer worked. I didn't try anything else to see what else didn't work. I just switched back to Wayland.

I'll keep digging and doing research. I can use the laptop. It just makes my eyes tired after a while. I do keep the colors set to a more warm setting with less blue and that does help. And I keep the brightness at about 50%.

Axios

Citfta Did you happen to try Kgamma from repo?
Let me know what it does

stekte

Before moving to solus i was a arch linux user. There was a program in their AUR called sct
(screen color temperature) which i had it installed and used . It can be found here https://github.com/faf0/sct

TraceyC

Axios Did you happen to try Kgamma from repo?

kgamma isn't a standalone program, it's one of the "kcms", a control panel (like the ones in System Settings). That's why it isn't listed in Discover.

It's disabled in Wayland because kgamma doesn't work with Wayland. That's why I didn't suggest it. I wouldn't bother trying to download and compile it. I'm sorry you got sent down this rabbit hole.

When it's made to work with Wayland it will show up in System Settings. Work is happening on this.

Citfta

Well this is a little strange. When I looked for kgamma in Discover it doesn't find it. If I look for Kgamma in the software center it shows it is installed. But if I look for it in the menu with a search it comes back with nothing except a suggestion to look online. The software center shows it to be a zipped folder but I don't know where it is hiding.

I downloaded and unzipped wl-gammactl-main. But the instructions for building it don't seem to work on Solus.
Here's what I got:
carrollb@carroll-solus ~/Gamma/wl-gammactl-main $ meson build
bash: meson: command not found
carrollb@carroll-solus ~/Gamma/wl-gammactl-main $ ninja -c build
bash: ninja: command not found
carrollb@carroll-solus ~/Gamma/wl-gammactl-main $

So I thought maybe since I have already inzipped it I would try this:
carrollb@carroll-solus ~/Gamma/wl-gammactl-main $ wl-gammactl
bash: wl-gammactl: command not found
carrollb@carroll-solus ~/Gamma/wl-gammactl-main $

The website said those commands should work on most Linux versions. But I guess Solus isn't one of them.
I did open Konsole inside the wl-gammactl folder.

Axios

Citfta What if you run (kcmshell5 kgamma) from terminal?

Ya it doesnt show for me in gnome software either but does in solus center
All these years on Solus never built anything..

alfisya

Citfta Before compiling any software you have to install the development tools (like any other distro). For Solus, as stated in help center :

sudo eopkg it -c system.devel
