[lubuntu-users] .icc colour profiles

[scrooyahoo at riseup.net]

I have a few questions about colour profiles.

Does Lubuntu make use of colour profiles?
If yes,
Where are they stored?
How do I change them?

I have a system that doesn't seem to have a correct gamma setting, but I 
can't figure out how to adjust this.

These instructions don't seem to get me any further

I installed al that stuff, but this still doesn't seem to change 
anything.

It's stuff like this why i don't like laptops, there is never a easy way 
to do display corrections. On an external monitor it is easy to tweak a 
few things just to make things a bit more easy on the eyes on a crappy 
display. But on a laptop people are stuck with the setting that is there 
by default... And with some displays the default gamma setting is far 
from ideal.  It would be nice to have a simple tool to change settings 
or load different profiles.
Something like on a external monitor. (that does not affect the system 
colours)

It would be cool to do a real calibration, but a straightforward manual 
option would be good enough for most people. Then you at least have some 
control to safe your eyes, or reduce a headache.
