Comment 9 for bug 123205

Same problem on my external monitor 1680x1050: the image is not centered .. like ten black centimeters on left side.

I have not any graphic effect actived, any way I have follow the instructions:
* Uncheck "Detect Outputs";
* In "Ouputs": 1680x1050+0+0

I have to hack the i180 on every reboot with:

915resolution 3a 1680 1050 8 1840 1080
915resolution 4b 1680 1050 16 1840 1080
915resolution 5a 1680 1050 32 1840 1080

I obtain the resolution but the image is not centered.
