Switching Video Cards

[Conor Klecker]

A success!

Right away after the install, Ubuntu found my video card and wanted to
install the driver. But since I downloaded the .run file of the latest
version of the NVIDIA drivers:
http://us.download.nvidia.com/XFree86/Linux-x86_64/310.14/NVIDIA-Linux-x86_64-310.14.run

I wanted to hand install it. So I had to log out of X session, but the
installer said that it the pre-install script failed. I read the
pre-install script:

#!/bin/sh
# Trigger an error exit status to prevent the installer from overwriting
# Ubuntu's nvidia packages.
exit 1

So I think that is just fine. I skipped the error the next time it popped
up. Then I got a message saying the computer was still using another driver
and if it wanted it to block it out. With this:
mythman at hp64myth:/etc/modprobe.d$ cat nvidia-installer-disable-nouveau.conf
# generated by nvidia-installer
blacklist nouveau
options nouveau modeset=0
Then reboot to let that take effect
I was then able to install the driver, I let it update my Xorg files.
Reboot
Set MythTV to use VDPAU High,
And now, when I playback an encoded blu-ray file (h264 mkv) that would
choke about every 15 sec and use 95-100% CPU looks like this:

Thanks for the help
