zb3 / gnome-gamma-tool

A command-line tool that lets you change gamma in GNOME and Cinnamon (with Wayland). You can also adjust contrast and brightness. It works by creating a color profile with the VCGT table, so that changes are persistent and don't interfere with other settings like night light.

After updates on Ubuntu 22.04.2 doesn't work #11

After updates on Ubuntu 22.04.2 doesn't work with wayland. If I use X11 session, script changes gamma, but doesn't work with wayland. I have hybrid intel + nvidia graphisc. Everything worked before updates

If you go to Settings -> Color, do you see the new profile? What if you click on it? I'm observing a problem on Fedora 38, that it "sometimes" doesn't work and there's a delay when switching profiles, maybe it's related to that.

Also if you see an error message, please include it here.

Importantly, does the "check mark" near the profile name appear? Does it appear immediately?

изображение Everithink looks normal, but settings doesn't change anything in wayland session

@dotmitsu , just to make sure, IF you double click on the automatic profile, does the checkmark appear next to it? And does the same thing happen when you double click the gnome-gamma-tool again?

I'll need to test this on some live Ubuntu 22.04.2 image later, but unfortunately it appears that this is a bug somewhere in wayland and this means the fix might not arrive soon..

It was Ubuntu kernel bug. I updated kernel to 6.3.1 and now everything works good. Thanks))
