Looks like there is finally some support for linux 3.13/3.14 ! The current patches seem no longer needed. It doesn’t compile on 3.14-rc5 though, so it might still need some changes.

EDIT: Seem like it’s 3.13 compatible, for 3.14 this is needed:

           GLX Renderer: GeForce GTX 750 Ti/PCIe/SSE2 GLX Version: 4.4.0 NVIDIA 334.21

Only the little include-patch is needed for 3.14.

Which driver version is the right one for scientific linux 6.5-i686/x86_64 ?

card #1: MSI GTX 750 Ti Gaming 2GB in PCIex16_1
card #2: NVidia Quadro 1800 FX installed in PCIex16_2

Do I have to
a) first boot just with Quadro 1800 FX
b) update drivers ready for MSI-GeForce-GTX-750-Ti-Gaming >> http://www.nvidia.com/download/driverResults.aspx/73666/en-us
c) install MSI-GeForce-GTX-750-Ti-Gaming
d) boot from hard disk

Would the following be wise:
#yum --enable elrepo install nvidia-detect
./nvidia-detect
#yum --enable elrepo install …
i.e. will there be a risk to get non-working updates ?

Booting from DVD fails once Linux start to detect hardwara it dies(tilts)

I could not update drivers from MSI DVD, because Linux kernel died once the process
handling this new GPU card died.

Current non-working configuration
Quadro 1800 FX installed in PCIex16_1 (blue socket) with one LCD via DisplayPort and another via DVI-D port
OK serving one LCD via DisplayPort and another via DVI-D port
MSI-GeForce-GTX-750-Ti-Gaming in PCIex16_2 (blue socket), no monitors connected
OS: scientific linux 6.5-i686/x86_64 with old GPU-drivers

Example 1 : failed DVD Boot
right monitor connected via DVI-D to MSI-GeForce-GTX-750-Ti-Gaming card
Sci-Linux seemed to detect existing hardware and software
left monitor dark - connected via DisplayPort to NVidia Quadro 1800 FX in PCIex16_2 (blue)
running /sbin/loader
detecting hardware <-- *** dies(tilts) here ***

Example 2: booting from hard disk and DVD with only new GPU
*** nouveau E[ PMC unknown interrupt ] ***

Example 3: Quadro 1800 FX in PCIex16_1 serving both displays, 750-Ti in PCIex16_2 without display

both screen show Linux start <=> Quadro 1800 FX works as before!
Linux kernel in panic! => Linux did not start => unable to continue and therefore unable to update GPU-drivers

One post should be enough. ;)
