I added to that “Resources” article how to set screen brightness from terminal (Konsole). The solutions in that article are used over most Linux distros, this is by no means an OM only problem.
@yusssufff Thank you. Even a “It did not work” is a feedback.
Can you please confirm that you tried all the workarounds? So to be sure we’ll have to look for further solutions (hopefully)
thank you for reply!
Yes i did try all the processes. Well the second one isn’t actually aimed at solving the brightness gui control, but more a command line workaround…
On this notebook it is “LVDS-1” other possible valures could be VGA-1, HDMI-1, or DP-1 or something similar to those. There may be other possible values.
Next the brightness value must be between 0.0 to 1.0 where 0.0 refers the dimmest (full black) and 1.0 refers the brightest value. For example, to set screen brightness value as 0.6, run:
$ xrandr --output LVDS-1 --brightness 0.6
To go back to normal brightness, run:
$ xrandr --output LVDS-1 --brightness 1.0
One can do one’s own internet search and find other ways to set laptop screen brightness from terminal (Konsole). One may possibly find other permanent solutions I have missed, if so please let me know.
There probably is some command that works in plasma-wayland I just do not know what that may be. So I have asked OM devs about this at OpenMandriva matrix channel. You and all users are welcome there as well.
This page shows graphics for ThinkPad L430 as “Intel® HD graphics 4000 (integrated)”.
Interesting… well i never had a display problem with any linux distribution on this machine so far… So yes it seems OM specific…
Thanks a lot for the links and the research!
@AngryPenguin added the wlr-randr package to repositories. For ROME (rolling repositories) it is in main/testing repo. To install for x86_64 ROME system:
$ sudo dnf --refresh in wlr-randr --enablerepo rolling-testing-x86_64
That command only installs the package wlr-randr. You use it in terminal (Konsole in KDE Plasma). Start with running wlr-randr --help. I’ll look at this on my old ASUS notebooks (in Plasma desktop) when I get some time. I don’t know much about this package except that I think it is a substitute for xrandr. Whether it works in OMLx is unknown until people test it.
I have not watched this video yet but I believe Hans de Goede is the person at Red Hat working on this. I will watch when I get some time. Found that here.
Bytheway i also tried to switch on “night mode” which usually makes the display a bit yellowish.
But zero response.
So night mode isnt working either…
Its about the whole control of the display i guess?
