[PlanetCCRMA] NVIDIA and RT Kernel (Fedora 20)

[Steve Duell]

Jeremy,

Thanks indeed for the detailed steps.  Here's how it went:


1. make sure you have basic software development packages
installed so you can compile stuff

(wasn't sure what I needed, so I just installed gcc c++ package)

2.  install the kernel-devel packages for stock kernel

(no problem)

3. uninstall any other type of nvidia driver and/or noveau

(I did this through the package manager - appeared to do the job)

4. install nvidia akmod while running stock kernel

(check)

5. reboot and make sure akmod working first with stock kernel

(Nvidia drivers built successfully & working great on the stock kernel.)

6. once it does then install the CCRMA stuff/realtime kernel but make
sure you also install the kernel-rt-devel* BEFORE you reboot.

(done)

Upon rebooting into the CCRMA kernel, the bootloader animation made it
almost to the end before the system started running through a checklist.  I
saw in that list that it was attempting to build from a kmod package.
 Other entries appeared after that, and then the system hung on the message
"starting Avahi DNS something...".  I waited 5 minutes with no activity,
then went to the virtual terminal and ran the grep commands.  They returned
no nouveau or nvidia modules.  So I guess it's as you say - the nvidia
drivers for this kernel didn't compile.

I have some idea about why this may be:

- Even though I attempted to install the regular i686 kernel package, I
noticed that the package manager gave me a PAE version.  I don't think I
need this, as I'm pretty sure I don't have 4 gigs of RAM. Is it possible to
force the installation of the non-PAE version through the terminal?

- Maybe there is another development package I need besides the gcc one?

Anyway, thanks again for the help - you've helped me get farther along in
the process than I've been able to so far on my own.  Much appreciated!

-Steve
