Black Screen

Hi All.

Linux Noob here.

I have a fresh install of openSuse 11.3 installed. But after the install the auto reboot nothing happens screen turns off, i restart comp grub came up

openSuse (Default)
Failsafe openSuse
Windows 7

i select default the little gecko loading screen comes up then after 15sec screen goes black screen actually goes into idle mode, button pressing mouse moving nothing effects it.

I reboot again select failsafe, text screen comes up going through list everything green, then screen turns black doest go into standby just black screen.

I reboot try default with nomodeset loading runs same as failsafe except when comes to x-server screen goes black.

I have 2 displays a 18" Dell digital lcd Monitor, and my 26" TFT TV, They are both connected to a Gigabyte Nvidia GeForce 8400 GS, TV with HDMI and Monitor with DVI-I. I have a second 18" Dell LCD Monitor, which i had connected with D-Sub but i couldnt get all 3 working so disconnected second monitor, as i wanted tv over monitor.

I had ubuntu 10.10 running before the opensuse 11.3 install it worked fine but i wanted to try suse.

I thought it might have been that i was picking KDE desktop then adding Gnome later in installation, so tried reinstalling default install same problem, tried gnome alone same issue, tried gnome and KDE and same issue. so i put original idea back on KDE and gnome later in install. and im sticking with this until i fix as its the one i want. but if i really have to i will switch back to ubuntu.

Any and All help would be greatly appreciated.

I have no Linux experience.

Thank you all

Running twin screens you probably need to look at the proprietary NVidia driver.
