TwinView setup [solved]

[Urza9814]

So I recently got a new motherboard, and as a result I had to get a PCI-e video card. Since I don't game much and have always heard NVidia drivers work better on Linux, I got a NVidia GeForce 7200. Now, I downloaded the drivers from the NVidia website, but I can't get them to work. They give the following error:

ERROR: Unable to load the kernel module 'nvidia.ko'.  This happens most
   frequently when this kernel module was built against the wrong or
   improperly configured kernel sources, with a version of gcc that differs
   from the one used to build the target kernel, or if a driver such as
   rivafb/nvidiafb is present and prevents the NVIDIA kernel module from
   obtaining ownership of the NVIDIA graphics device(s).

   Please see the log entries 'Kernel module load error' and 'Kernel
   messages' at the end of the file '/var/log/nvidia-installer.log' for
   more information.
-> Kernel module load error: insmod: error inserting './usr/src/nv/nvidia.ko':
  -1 Invalid module format

So for now, I'm using the GeForce FX - GeForce 7950 driver that comes with Mandriva. It seems to work though. I tried to follow this tutorial to get TwinView working, but my second monitor still displays junk. Kinda fuzzy blue and such. I did managed to get a very long desktop, but it didn't go on to my second monitor. Attached is a copy of my xorg.conf (it wouldn't let me upload a .conf file)xorg.conf.txt

You need to check the version of the kernel-source file against the running kernel. They must match. You have a mismatch, which is causing this error.

[Urza9814]

See, I read that elsewhere too, but uname-r outputs 2.6.17-13mdv, and the only kernel source files I seem to have installed are 2.6.17-13mdv.

[root@localhost urza9814]# uname -r
2.6.17-13mdv
[root@localhost urza9814]# dir /usr/src
linux  linux-2.6.17-13mdv  rpm
[root@localhost urza9814]# dir /lib/modules
2.6.17-13mdv

Am I missing something?

[Ixthusdan]

They seem to match. I remember something a while back about this issue, in which the sources were compiled against the wrong version of libraries. Perhaps you should update your kernel, I saw that 2.6.17-17 was the latest for the 2007 series. I have Nvidia products in every machine I own, but my memory could be faulty. Have you tried using urpmi and the dkms packages in the repository?

[Urza9814]

Oh hey, I just needed to install DKMS. Working pretty well now, but I still have one problem. My main monitor is a standard CRT...21" I think, something like that...my secondary is a flat panel wide screen. The secondary monitor however, probably because it's widescreen, isn't reaching the whole way down. Like, when I had it set up with my ATi card, the height (in pixels) of both monitors was the same...but now, my second monitor isn't displaying the last 50-100 pixels (they're there, it's just not showing them), so I can't see the panel on that side. Any ideas? I've tried playing around with the resolutions a bit, but that didn't seem to help.

[Ixthusdan]

I think the Nvidia utility can run both at different resolutions and frequencies. Check it out. Look under tools=>system tools=> nvidia display settings

[Urza9814]

Ah! There we go. It was in system > configuration > hardware for me though on KDE. But yes, everything is working now. Thanks :)
