GT 220 dual screen. Second screen on DVI or HDMI connector remains black
i'm using ubuntu 9.10 x64 and nvidia driver 190.53.
i have a CRT screen on the vga connector and a second one (a video projector LG 110AN) on the DVI connector.
the first one works perfectly but the second one remains black, with the mention "no signal", the same if a use the HDMI connector.
thanks for help
