To calibrate just press alt+f2
Then switch to the colour tab, then click calibrate, follow the steps in expert mode, taking care with each step
I'm not sure how to post the calibration of each step in one image, it does give a summary screen after calibration but i can't return to that screen.
Here is my calibration file - you can load it using the instructions above and clicking open from the menu in the colour options.

But it is always best to complete the calibration yourself for your screen.
My results are a better temperature, less warm, more definition between greys and better contrast which is obvious just from the menu bars and the desktop image.
With 40 - 60% brightness which is my typical brightness i don't have viewing angle issues until the reflections affect the contrast.
