mlt at mlt-laptop:~$ xgamma -gamma 1.0
-> Red  1.000, Green  1.000, Blue  1.000
<- Red  1.000, Green  1.000, Blue  1.000

I can't figure out options format for xrandr as
xrandr --gamma 1:1:1
prints usage instructions

mlt at mlt-laptop:~$ cat /proc/version
Linux version 2.6.38-10-generic (buildd at roseapple) (gcc version 4.5.2
(Ubuntu/Linaro 4.5.2-8ubuntu4) ) #44-Ubuntu SMP Thu Jun 2 21:32:54 UTC 2011

I'm not sure if OP on launchpad correctly described the problem. These noisy
dots happen only in some areas of the screen. Some of the dots are
jittery/non-steady. Also if I move mouse over impaired area, cursor looks okay.
First time I thought it may be overheating of my video card or bad memory, but
after a clean reboot everything works just fine.
