Xgamma not working in xorg 7.0

Question

My monitor is kinda fried so I used tkgamma/xgamma to make on the fly adjustments between image work and text editing. running xgamma on the command line has no effect on the monitors gamma adjustment, but xgamma reorts it's changed gamma;
xgamma -gamma 2.60
-> Red 1.000, Green 1.000, Blue 1.000
<Red> Red 2.600, Green 2.600, Blue 2.600
but no change on my monitor!
any ideas, I really like changing gamma on the fly, especialy in front of the windozers

Hi Ramien,
Try this.
Go to System Administration>>System Configuration>>Collaboration
Click on Real Time Collaboration (RTC)
Click on RTC Engine
Again on RTC Engine
Click New if there is no existing RTC Engine
Type
PollingIntervalBasis: 2
Click ok.
I hope you have already enabled the RTC on the default framework page.
If not, do it like this.
Go to Content Administration>> Portal Content>>Content Provided by SAP>>End User Content>>Standard Portal Users
Click on Default Framework Page
Here Open it and choose show all from the dropdown.
Check the radio buttton "Enable Real Time Collaboration (RTC)"
Click Save and Try Again.
For configuration of CLP(Collaboration Launch Pad) Please follow the link given below.
