Can not adjust screen temporature by software like redshift, flux, gammy, any other ways? like native commands to test if I can adjust screen temporature or find any misconfiguration of my system.
Specifications:
CPU: Intel i5-1240p
GPU: Intel Iris XE
kernel: linux515
laptop is HP Probook 450 G9
I already tried to reinstall drivers by mhwd, lightdm, linux515 kernel, linux-firmware, xorg-server
how did you install, configure and run it?
(when it did not do what you expected it to do
what was it what you expected it to do
and what happened instead?)
and, of course, the inxi -Fazy output that @brahma requested would/could be helpful
To make it clear, what I did yesterday is to use clonezilla to clone my original portable 1T HDD to 2T SSD and insert the 2T SSD into my new laptop after you help me fix the boot problem. But actually I find the problem of screen temporature also exist when booting with my original portable disk in my new laptop.
I use pamac-manager to install it. I didn’t configure it. In xfce, it shows in bottom right of the screen and when the time comes to night, it will auto adjust the temporature. I find it work in my old laptop. I want to adjust the screen temporature when it comes to night to make my eyes comfortable. In my new laptop, it doesn’t change the screen temporature at night. So I tried other softwares, all didn’t work.
[my@my-pc ~]$ redshift
Trying location provider `geoclue2'...
Using provider `geoclue2'.
Using method `randr'.
Waiting for initial location to become available...
Location: x.x N, x.x E
… with my (working) configuration
this command works - but only for a few seconds
then the configured settings take over again
… the color temp (3000 K) only changes for a very short time - just enough to notice it
white on black terminal text gets reddish for one or a few seconds
this is my configuration - I have set my location manually since I had trouble getting the automatic location provider to work
and I do not change location often enough or far away enough for the resulting difference to truly matter:
same result here - it is a service which is started with my Xfce session
if I just type “redshift”
nothing will happen
just as you just said
to start it via terminal - give it the proper command line options
or configure and start the service
log out and back in …
and , of course, nothing noticable will happen if your location is at daytime - only at nighttime will it change the color temp to 5000 K (from 6500 K at daytime)
If you used my location - it is well within daytime as of right now …
it’s just past 6 pm and still 3 hours away from sunset
