The Livna mailing list threads that you referenced show a

I have to concur with Lonni. I was having all kinds of libGL problems
which were fixed by switching to the "official" nVidia driver. I'm no
hardware guru, by any stretch of the imagination, but my problem is
fixed. Ric

I have to agree with Ric here. I never did get dkmk or whatever its
called to work even though I did ask for directions here, so I've been
doing the official nvidia way, from their latest linux 9755 build. No
detectable errors, none, nada, it just works. What it is, is a PITA
to have to do it everytime I boot a different kernel, which may be 5
or 6 times a day. But that's my choice as I play the role of the
canary. As for fighting with selinux, nope, disabled, end of
discussion.

I notice a significant speed increase as well, at least about 25% or so
faster. The application I was using kept crapping out with all kinds of
GL errors and segfaults. I updated the kernel, the livna drivers and
devel for both. I've battled this for months, never suspecting that
something so cintegral as a video driver would be broken and stay broken
upgrade after upgrade. I've been patient and spun my wheels late into
many many nights for naught, which kinda jerks me off guys. I've
bothered the living Hell out of the Croquet folks, who spun their wheels
trying to see if it was their problem. I installed the nVidia official
driver as the last ditch intervention and that worked. What can I say...
I've installed at least 10 kernels and 10 kmod-nvidia upgrades through
this saga, starting around November of last year. During all of this, on
the Croquet mail list, people using Linux were reporting "working out of
the box"! I felt like a piece of ham.

As you know, I test kernels for a hobby, and one of the biggest PITA's
ever is continually re-installing the nvidia driver since my kernel
maker/installer script copies everything already installed from that
version in /boot and /lib/modules to a .old version in case things go
aglay. Its an easy revert that way if they do. But that also means I
have to re-install the thing everytime I build a new kernel. Or for some
reason reboot to a known good kernel that's already had it installed
once, but nvidia in their paranoia somehow manages to kill it if a
different kernel has been booted since that one was.

Now, I won't say that this is the be-all and end-all of this, but a one
liner in my /etc/rc.d/rc.local script near the bottom that reads:
/root/bin/install-nvidia
calls the script below and installs the driver & runs a depmod to fix
everything, all in a second or less.

To use this, after the driver has been installed:
#> cp /lib/modules/`uname -r`/kernel/drivers/video/nvidia.ko /nvidia.ko

The script, save it wherever but /root/bin I'd already stuffed with lots
of other handy things and installed it in my $PATH so it was as handy as
any. After saving it, set the
exec bit with a "chmod +x /root/bin/install-nvidia"

--------cut here-----
#!/bin/bash
# this script should install the nvidia module and
# run a depmod -a `uname -r` IF the module is missing.
# a test deletion to check the opposite logic
# rm -f /lib/modules/`uname -r`/kernel/drivers/video/nvidia.ko
if [ -f /lib/modules/`uname -r`/kernel/drivers/video/nvidia.ko ]; then
echo nvidia.ko modules is already installed
exit 0
else
echo copying nvidia.ko into kernel modules tree

# move this file someplace out of sight if paranoid about stuff in /
cp /nvidia.ko /lib/modules/`uname -r`/kernel/drivers/video/nvidia.ko
echo running a depmod -a `uname -r`
depmod -a `uname -r`
fi
if [ -f /lib/modules/`uname -r`/kernel/drivers/video/nvidia.ko ]; then
echo nvidia.ko driver sucessfully installed
else
echo install of nvidia.ko driver failed
fi

-----to here--------

Have fun till it really does need a rebuild or a new driver is out, this
saves me about 2 or 3 minutes per reboot, and a heck of a lot of wear and
tear on the return key. I can go get some caffeine while its booting.
Legal according to nvidia? DamnedifIknow. Send me a C&D letter if you
care.

Humm, sitting here, it comes to me that this would also work
as /etc/rc(runlevel).d/S97install-nvidia if it simply returned OK|FAIL,
but I'm lazy & this works for me.
