This is directly connected LCD display, shown as LVDS.

As I understand, I should execute it, from running xorg. Am I right? If
I will find difference, what should I do ?

The refresh rate comes from Xorg.0.log. With xf86-video-intel the
display doesn't show any picture, only backlight is activated when I'm
starting X.
By the way, this MB has two LDVS outputs: LVDS1 and LVDS2. The second
one is not connected to anything, but in the log both are connected.
