The cause of a failure probably is a fault to load NVIDIA driver.
I have re-installed everything about NVIDIA – no positive results achieved.

I had re-generate XF86Config by # nvidia-xconfig in this one:

Please, help to load NVIDIA driver and use native res 1366x768 again.
Thanks for your time and effort!
