Have Intel motherboard. Graphics integrated. Ubuntu 12.04 showing to monitors, LVDS n VGA connected, but I have only VGA. And Ubuntu think that my monitor can show FullHD but really it can only 1280*1024. And VGA display was automatically configured to 1280*1024, LVDS - FullHD. And I can see just left half screen on a display. When I'm trying to disconnect LVDS - have a black screen. When I'm trying configure any resolution on any of this displays have an error or black screen randomly. xrandr and manipulation with it, couldn’t help, just a black screen
Once I'm trying to set 1024*768 on VGA display and have a normal screen but very big fonts and icons. In BIOS i can only turn off integated graphic and LVDS. But on motherboard no any PCI or PCI-Ex.
So I wanna set resolution to 1280*1024.
Thank for any help.
