nvdia driver installation issues

hi  lately i installed Devuan on my computer.
I was trying install Nvidia driver on my pc but after i shuted down  the x11
this showed up :
The NVIDIA driver does not support real-time kernels. If you
are using a stock distribution kernel, please install
a variant of this kernel that does not have the PREEMPT_RT
patch set applied; if this is a custom kernel, please
install a standard Linux kernel.  Then try installing the
NVIDIA kernel module again.
i searched but nothing
how can i solve this.
thanks !!

Re: nvdia driver installation issues

What kernel are you using? The message is clear. Either use a rt kernel or use nvidia driver, but you can't use both together. Which one is more important?

Edit: How are you installing the nvidia driver? Package from repo or binary from nvidia?

Re: nvdia driver installation issues

i guess NViDIA driver is more important;

i downloaded it from nvidia driver website;

Re: nvdia driver installation issues

OK, then, that's a weird message to get.
4.9.0-4-amd64 is not a realtime kernel.
4.9.0-4-rt-amd64 is a realtime kernel.

grep PREEMPT /boot/config*

That gives me the same thing for 4.9 in ascii and for 3.16 in jessie:

CONFIG_PREEMPT_NOTIFIERS=y
# CONFIG_PREEMPT_NONE is not set
CONFIG_PREEMPT_VOLUNTARY=y
# CONFIG_PREEMPT is not set

I don't have a 4.9 kernel on the box with the nvidia graphics right now, so I can't test this.

Re: nvdia driver installation issues

i checked the log file again.
actually  it says the kernel you install for is a PREEMPT_RT kernel !.
i guess its a patch thing.
i have no idea.

Re: nvdia driver installation issues

I found this. It's from 2014, so it may no longer be accurate. Also, please run the grep command I posted above to see if you get the same output that I got.
