I'm running Linux Mint 9 gnome on a Toshiba Satellite A105-S4211

With this,

inxi -G Graphics: Card Intel Mobile 945GM/GMS 943/940GML Express Integrated Graphics Controller X.Org 1.7.6 Res: [email protected] GLX Renderer Mesa DRI Intel 945GM GEM 20091221 2009Q4 x86/MMX/SSE2 GLX Version 1.4 Mesa 7.7.

And I want to know how to configure the monitor/graphic/video/driver/gamma settings.

What I really want to do is change the gamma settings on my computer. I was told that I can do this using the video card driver.

I want to know how to do that.

  • I vaguely recall an old program called xvidtune that might be what you want.

  • yes. That works. When I ran the xgamma man page I saw it. It works but I am too afraid to use it. I wish I could just figure out how to work with icc profiles . Apr 9, 2011 at 7:56

You should be able to adjust the gamma using the xgamma command.

  • Thanks Amazed. I can. And there is also xvidtune. After running it there is a warning and so I decided it was too dangerous for ignorant me to use. Apr 9, 2011 at 7:55

I think the program you are looking for is xvidtune.
