Hello,

 

I know that mostly this list is used for development though I wanted to know
if there is any option to set values for thing as Gamma, Contrast and
Brightness on the driver or if there is any way they can be set ?

Will there ever be a Control Center like the Windows version ?

The question arises for a reason that alike some people I have a bit of a
problem with glossy screens and also with contrast levels and such.

Thought being a Linux System's Engineer for company it's odd not being able
to use Linux at work cause of the odd nuance. It's even more "odd" when
people see me using Linux on a VMware so that I can get my contrast set from
Windows J

 

Thanks for any reply

 

Francisco

Hi! I'm no real expert, but I dare to guess some answers anyway...

> Will there ever be a Control Center like the Windows version ?

Probably not. It is not the job of a driver to communicate with the 
user. GUIs are made by other people. Your desktop environment could 
provide such a tool.

To increase brightness to 150%, you can use

xrandr --output <which_one> --brightness 1.5

To reduce contrast to 75%, you can use

xrandr --output <which_one> --gamma 0.75:0.75:0.75

Ok, sorry, gamma is not the same as contrast. But gamma can be used to 
achieve similar shifts of the relation of dark to bright colors, so it 
might be suitable to get the desired effect here.
