But biggest problem is that colors of the picture are not solid, sta= ble - they are somehow blinking or flickering. Sometime I think may be back= lights of LCD panel works different. And after hour or two eyes start noti= ce it, it is looks like colors is not constant, they always changes, little= bit but they are "playing". > It is very noticeable if I log into different TTY (not graphical) and jus= t start "mc" - it present for eyes. > It is impossible to record, sorry. > > Thanks for help. > >> >> > I have tried OpenSuse 11.2, which is with newer kernel >> and it shows the same bad like Fedora 12.
