[clue-tech] Ubuntu Fixes

[David L. Willson]

Hoping to save somebody some time here.

1) "sudo apt-get install nvidia-glx-new" installs a recent nvidia driver
2) "sudo nvidia-glx-config enable" enables the glx driver, by changing
Driver in the Device section of xorg.conf from "nv" to "nvidia"
3) Now X won't start, because it also adds 'BusID "PCI:1:5:0"' whether
or not that's really the BusID of your card.
3) The BusID does not need to be specified, and deleting the line allows
X to startup OK again.  (Maybe it's needed for multiple-video-adapter
configurations?)
4) Your Modes lines have been replaced by "1024x768" and lower.  Change
all Modes lines to include only the resolutions you use.
5) Now, you still can't turn on "Desktop Effects" or Beryl, because when
you do the window decorations disappear. In order to turn on Beryl or
"Desktop Effects" (which is Compiz, I think), you'll need to "sudo
nvidia-xconfig --add-argb-glx-visuals", which adds 'Option
"AddARGBGLXVisuals" "True"' to Screen "Default Screen" section of
xorg.conf.

Now, you can turn on "Desktop Effects" or apt-get Beryl.  If you go with
the latter, let me recommend that you apt-get "emerald-themes" too, so
that you will have access to the uber-cool "Scaled_Black_Mod" theme.
