I installed Crunchbang Linux. I successfully installed the ATI drivers, and all works well. Except that the colors are bit weird. Hard to say what exactly is wrong, it is the notion that on another laptop (or windows on the same laptop) everything looks better. It's probably some combination of brightness/contrast/gamma settings.

Is there any comfortable way to adjust the display settings under Crunchbang, or Linux in general? Some nice calibration tool? I don't need a photography-quality display.

I used aticonfig to djust brigtness and contrast, and xgamma for gamma. but they are not very handy.

This question interests me greatly, but I am a bit doubtful that you'll receive a proper answer. On a MacBook, I've noticed that images in Safari are noticeably more vivid than those in Firefox. I mention this anecdotally because so many things are at play when you start to assess display quality that it's hard to assess which layer is the culprit. –  solo Apr 6 '12 at 6:51
    
The point is that I don't even know if bright./contr./gamma are sufficient to make the colors vivid and nice looking, or if there is some other "magic knob" somewhere there that I am not aware of –  Jakub M. Apr 6 '12 at 7:45

You should check out Monica - it's a handy GUI frontend that let's you calibrate your monitor. Monica depends on fltk-devel AFAIK. Read the wiki article on color management under Linux.

A little bonus (and one of my favourite monitor tools) is Redshift which is the Linux equivalent of F.lux. It sets the temperature of your monitor according to the position of the sun, so that your eyes will be more confortable staring at your screen at late hours.

I used Redshift and it works well. Monica gave strange results –  Jakub M. Jun 7 '12 at 8:17

There is a gamma calibration tool in the gnustep packages (at least in Debian). You may want to give it a try. IIRC, it allowed adjustment of the channels independently.
