Hi, I would like to know How to adjust screen contrast in manjaro?
Thanks!
As you have left no clues - generally speaking - that is something you do hardware wise.
Every monitor has a menu used to adjust screen brightness and contrast.
i use a laptop! Dell vostro
And I mean how to decrease contrast with software of course, in windows i have the intel graphic panel, but in manjaro i dont know how ?
Hello @Karlos
After installing xorg-xgamma
you could adjuste it with xgamma -gamma 0.3
or with xrandr:
xrandr --output <screen> --gamma red[:green:blue]
like this:
xrandr --output HDMI-0 --gamma 0.8:0.8:0.8
@megavolt but when you restart your pc it turns like it it is before!
is there any solution? for these!?
@Karlos Yes… you can add it in the Xorg.conf manually (which you have to create before not there):
Create a file in /etc/X11/xorg.conf.d/40-gamma.conf and put this into it:
Section "Monitor"
Identifier "HDMI-0"
Gamma "0.8 0.8 0.8"
EndSection
or add the command in ~/.xinitrc
before exec $(get_session)
like this:
xrandr --output HDMI-0 --gamma 0.8:0.8:0.8 &
exec $(get_session)
Create a file called 40-gamma.conf
on the path /etc/X11/xorg.conf.d/
and put the text into it. Save it. Then it will be set permanently on every boot.
sudo nano /etc/X11/xorg.conf.d/40-gamma.conf
then copy&paste the text into it. Save it with CTRL + S and close it with CTRL + X.
After reboot it be should set.
About the numbers: 99 = lowest priority, 00 = highest priority. So if there are other files in /etc/X11/xorg.conf.d/
or the file xorg.conf
is available in /etc/X11/
with the same “Monitor” Section it could be skipped.
