I have just upgraded my box to all new hardware which includes an Nvidia Geforce 9400 graphics card.

I have had fedora 10 on my system and now have put mandriva 9 on and have the same problem with both.

When I load the Nvidia drivers for my Geforce 9400 video card the xserver won't start. All I get is a blank screen and the monitor says "No Connection"

When I had Fedora 10 on I renamed the xorg.conf and restarted x and it worked a couple of times then x wouldn't come up at all, so I installed mandriva 8 to see if it was ok.

Mandriva 8 was fine except it had the vesa driver enabled. When I loaded mandriva 9 and went into the hardware configure it detected the NVidia card and downloaded and installed all the drivers. When I rebooted x wouldn't start again, so I swapped back to the xorg.conf with the vesa driver and now it works.

Is there a problem with the graphics card or the Nvidia drivers?

Have others had similar problems?

Any body get the GeForce 9400 GT NVIDIA to do a dual monitor yet? I have tried all of what I can find on the net, I am rather new so re-writing links and drivers and kernels is a little bit above my head. Running SuSE Linux 10.2, works find in Windows XP Pro.

hi hinesbx
there is no outofthebox solution for dual monitor at linux. At my company we tried many ways to work on dual monitors with different resolutions, but we failed every time. Using Linux was too costly for such reasons so we switched to Windows.
I have at home one 9400 on a fedora 10 computer, at fresh install of fedora 10 i can use two 22" monitors at 1440*900 resolution but cannot use 1680*1050 yet. At windows it is a piece of cake to use.

Use lspci command at terminal
then find a line similar to this one

01:00.0 VGA compatible controller: nVidia Corporation Device 0641 (rev a1)

The 0641 is the pci id of vga card, in my case it is 0641.

You have to go to nvidia official site below and search your pci id.

If you are lucky you can see your card (i am among unlucky ones)

D'load compatible drivers.
Stop all x server environment or restart your computer w/o graphical environment.

Use command sh to open your driver file.
If you are lucky it will install it, and compile your kernel.
(i was also unlucky here again)

Then set your visual settings to use your card.

Of course this is Linux world and nothing works out of the box!,
you will live such things every time you change softwares, hardwares and etc..
with huge amount of time consuming processes.

If your time is valuable use Windows.

Also here is how to install nvidia on Suse, hope helps!

Hi hinesbx again,
after my last message i tried it on my computer by installing a Suse 10.2 on an older harddrive.

When i make a fresh install with only one monitor which has a high resolution (ie 1600*1200 or 1680*1050 ) system recognizes high resolution. Then put another big monitor to your graphics card, it automatically clones the screen with the same resolution to the other monitor.

Perhaps some kind of older softwares or drivers cause system not to recognize the resolution as usual.

But problem also continues when i try to add another monitor. In my case one monitor with 1680*1050 resolution works ok, when i add another 1680*1050 monitor, both monitors show resolution of 1024*768 which is very funny. So this is free linux, no one expects better from all
contributing developers. They give their all effort freely to create a nice system but world depends on money, so Microsoft Windows have
it for better solutions.

I've had a similar problem happen to me. However, it was that the refresh rate of the monitor clashed with the vid card. If you have another monitor lying about use that and see if it works. If so, change your display options to the proper settings.
