Smile nvidia graphics, 2 kernels, 2 window managers is it possible?

Hi, I have 2 kernels, one RT, the other is not.

The newer kernel (2.6.28.x.x mdv) is my main desktop, for normal every day tasks,

but the other, RT kernel (2.6.26.x.rt mdv), is specifically for Real-Time

monitoring of Audio when Recording sound (Multi-track) on my system.

I have more system info available if required, But

My main question is...

Can I have 3d graphics acceleration installed on both kernels?

I use the nvidia proprietary driver module, 177.82, but if I try to

install it for the other kernel, nvidia-installer un-installs the

current one.

What I want to do is cut back on desktop fx when using the recorder by

having a separate user, "music" with xfce, but still keep my usual set-up

for everyday use without having to install the graphics all the time.

I can get around this by editing the /etc/X11/xorg.conf file each time

I change tasks, but I don't get the benefit of the hardware GPU and

memory using vesa.

I'm new to this kind of hacking, but I'm sure one of you

know how to do it.

I wrote a tute for setting up RT monitoring,

and am familiar with some of the configurations, but this is new to me.

I use kde4 for everyday bling and computer work,

like web-browsing and doc writing etc.

Any tips?

Thanks heaps, Glenn

nvidia-installer does have options for what you want to do. Read output of 'nvidia-installer -A'

Cool Solved

Thank you Didier, that's it.

 -K, --kernel-module-only
      Install a kernel module only, and do not uninstall the existing driver.
This is intended to be used to install kernel modules for
additional kernels (in cases where you might boot between several 
different kernels).
To use this option, you must already have a
driver installed, and the version of the installed driver must match
the version of this kernel module.
Thanks heaps, Glenn
