Setting gamma ubuntu

I believe the command is something like this:

Quote:

'xgamma -rgamma 1 -ggamma 1 -bgamma 1'

and you adjust the brightness in increments of .1 ie:

Quote:

'xgamma -rgamma .9 -ggamma .9 -bgamma .9'

or simplified

Quote:

xgamma -gamma .5

or

Quote:

xgamma -gamma .25

xgamma is adjutable to 3 decimal places.
