ATI and Nvidia drivers on Arch Linux
I thought that having both drivers on a test system would be handy and looked through many forums. In the end I installed ATI drivers, intel drivers, vesa and nouveau (for Nvidia) on an arch linux system that I have installed on a 4GB flash drive-compiz stand alone windows manager with avant window navigator panel installed. (Nvidia proprietary drivers conflict with ATI but Nouveau does not) I can't produce a sphere (when using Nouveau) when using compiz cube with reflection this way but most other 3D/composite functions I have tried work as expected. I did have to sacrifice a graphical bootup process as nouveau handles framebuffering funny too. I can plug into an ATI or Nvidia using system and everything works. I also have a windoows manager installed that does not make use of compositing so I could use vesa drivers as a fallback on incompatible systems.
An easy way to make a portable system for use on just about any system is to use tipsy puppy linux (http://www.murga-linux.com/puppy/vie...t=41785)-comes complete with working compiz out of box or lighthouse puppy (http://www.lhpup.org/) with mariner.sfs loaded for switching between different video drivers and a good choice of different window managers.
If someone wants to try the archlinux flash drive, drop me a message and I can upload an image file that be installed to your own flash drive in 2 minutes.(This may take 2 days to upload from my end as my internet connection is slow and the image is 3.73 GB)
