THANKS !
The following (and previous) actions were performed by booting from hard disk,
where the scientific Linux was installed and working fine before this new GPU-card:
Step 1/33) booted Scientific
Step 2/33) pressed SHIFT key
Step 3/33) got
GNU GRUB version 0.97
Linux (2.6.32-431.5.1.e16.x86_64)
Step 4/33) selected e = edit
Step 5/33) selected kernel
Step 6/33) edited <root rhgb quiet ← splash nomodeset
where
a) ** splash seemed to prevent opening virtual terminal which was used to install NVidia driver
b) nomodeset ok
Step 7/33) sci-linux booted ok
Step 8/33) downloaded NVIDIA-Linux-x86_64-334.21.run
Step 9/33) met several problems due to splash
Step 10/33) repeated 1 - 5
Step 11/33) edited <root rhgb quiet ← nomodeset
Step 12/33) sci-linux booted ok
Step 14/33) started command mode
Step 15/33) telinit 3
Step 16/33) ./NVIDIA-Linux-x86_64-334.21.run
Step 17/33) yes to “Install NVIDIA’s 32-bit compability libraries?”
Step 18/33) selected “run nvidia-xconfig utility to automatically update x config file”
Step 19/33) saw “Installation of NVIDIA Acceleated Graphics Drives for Linux_x86_64 (version: 334.21) is now complete”
Step 20/33) reset
Step 21/33) booted and forgot to press SHIFT
Step 22/33) saw only ** nouveau E uknown intr ** in both screens
Step 23/33) reset
Step 24/33) boot with SHIFT
Step 25/33) edited <root rhgb quiet ← nomodeset
Step 26/33) verified NVIDAI X Server Settings
a) GPU 0 - (Quadro FX 1800) ← Samsung Syncmaster DFP-1 and DFP-1 connected ok
b) GPU 1 - (GeForce GTX 750 Ti) <–no displays i.e. OK because acting as GPU computing platform
+ no conflicts in interrupt levels
+ no conflicts in PCI-bus addresses
Step 27/33) open & to be done permanently until nouveau drivers will be available: <root rhgb quiet nomodeset
question 1: how, what is the safest (not necessary coolest) way to proceed - ideas welcome!
Step 28/33) open & to be done: install OpenCL for these cards
question 2: how, what is the safest (not necessary coolest) way to proceed - ideas welcome!
Step 29/33) open & to be done: install CUDA for these cards
question 3: how, what is the safest (not necessary coolest) way to proceed - ideas welcome!
Step 30/33) open & to be done: how to open a new topic in https://devtalk.nvidia.com/ ?
problem: how to create topic headers when
a) one does NOT get any header prompts!
b) not even my fellow guys see there any field to be fille because of black & green screen!
Step 33/33) learned so far (in hard way):
a) ** “designed to fit-products” are hard to find - check how well/whether a new GPU-card will fit inside the chassis!
b) ** too many power on/off may brake something - one USB-disk already lost in this process!
c) ** one process with interrupt problems serving a GPU may halt the whole Linux!
~ one would expect OS to kill the process and proceed instead of having “kernel in panic”!
d) ** reliable would serve better than cool specially in the boot process to get OS booted ok!
~ unreliable GPU drivers in kernel should handle exceptions!
e) ** “business as usual” with a new GPU-card
~ delivery late from dealer, suppor-CD only for Windows, bugs in software such as OpenCL/CUDA, no kernel drivers …!
f) ** only Windows support from dealers
g) ++ GOOD Linux community support - THANKS GUYS! ++
