monitor adjustment on linux


i just got a new samsung monitor, and it comes with a windows only app that changes the output color. on linux without it, i cannot adjust the colors like i want. is there a way to do this in linux.

Kgamma is an available GUI, however, I have never used it. There may also be some color corrction and other tools available for your specific video card under Linux... do some searching, if it's available it should not be hard to find...

icga: on FC4 - under gnome: main menue > desktop > system settings > display
this lets you adjust the screen resolution and colours, and probably is what you want.

What do you mean by "colour adjustment"?
What is it about the colours you want to adjust?
What is it about the screen colours you have now that you want to change?
Did you try KGamma as suggested in the other posts?

There are many many ways of adjusting the colours viewed on your screen.
The windows only app was likely some sort of non-standard driver for you monitor - have you tried the manufacturers website to see if there is a linux version?

What is your monitor anyway? (Samsung make a wide range...)
What is your video card?
Are these correctly identified by FC4?
Are the correct/best modules for them loaded?

What have you tried in your personal attempts to get this the way you want and what happened.

Read "advice" in my sig.

cant use kgamma because it is for kde. by color adjustment i mean gamma i think. it let me pretty much make the colors brighter and more vivid. the monitor is a samsung 213t on a radeon 9500pro.

EDIT:: BTW i am using gnome :END EDIT

xgamma (1x) alter a monitors gamma correction through the x-server
you may want to look at gconf

or you could just adjust the colour balance using the monitors controls.

well on the samsung 213t in digital you cannot adjust color, which was my problem in the first place.

but i looked into xgamma somemore, and it is working quite good. set it to 1.3 for now, will finetune at a later time.

thx all!

very good - don't forget to stick your distro and your location into your profile ("edit profile" under "My LQ" on the right.)

You may want to stick that monitor in the HCL lists too. (select HCL from the top of the page and follow your nose.)

I came across monica recently, and found it to
be a nice GUI for that purpose, too. Requires
FLTK, though.


Cheers,
Tink
