As I understand, I should execute it, from running xorg. Am I right?

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. -- Jarek
