[PROBLEM] Screen calibration not saved after switching to TV and back

[starous]

Guys,

I've been struggling with this issue for a long time, and still can not find the root cause. Please, help.

I calibrate my xbian, because it doesn't fit on my TV. The edges hide behind the frame. But whenever I switch to TV and then back to xbian, the calibration gets lost. I have to restart my pi to get it back.

Do you know what is needed to be set, so this doesn't happen?

I have Raspi B (512mg) with the latest xbian version (kodi 14.2)
My pi is connected to Ethernet and to my TV.

Thanks
