I'm trying to install a linux distribution on my PC.

I have a GeForce 8400 GS with two connected monitors. I tried with Fedora 12 and Ubuntu 9.10 (both 64 and 32 bit) and the live cd cannot boot properly.

I don't get a visible error on Ubuntu, it simply hangs up during the boot. With Fedora I get this error:

[drm] Modeset on unsupported output type
[drm] Table 0x0000 not found for 1/1 using first

I tried to disconnect one of the two monitor and was able to install on my HD and boot from there, but if I try to connect the second monitor again I cannot boot.

Do I need to install something else? (a driver for my video card for example).

Install the NVidia-Drivers (using the Hardware-Manager in Ubuntu, not the Website-Download) and try again. – Bobby Apr 7 '10 at 9:17
Thanks quack quixote for corrections. @Bobby I'll try – Andrea Polci Apr 7 '10 at 9:21
@Bobby Using Hardware-Drivers to install nvidia drivers solved the boot problem. I still cannot use the second monitor but now I know what to look at. If you cange your comment into an aswer I'll accept it – Andrea Polci Apr 7 '10 at 19:30

Install the NVidia-Drivers (using the Hardware-Manager in Ubuntu, not the Website-Download) and try again. I had a similar situation once, and it seemed like the generic vesa driver couldn't handle the monitor + graphiccard combination for some reason.

From there you should be able to use the Nvidia-Settings tool (located in System, Administration) for setting up your two monitors.

do you have another box you can try? are you certain the card works? i've had more than two 8400 GS's dead on arrival. one was a bfg tech the other an nvidia

I haven't another box. I currently use the same machine in windows vista with two monitors so I suppose the video card isn't broken. – Andrea Polci Apr 7 '10 at 9:20
