graphics card driver

First, how do you know it's sluggish?
Next, do you really know which driver you need, by its linux name, for each machine?

In most cases for me, and luckily so, Knoppix gets it right.
I've had problems on some other linuxes, however.
Knoppix has built-in a lot of these drivers.

Finally, by manufacturer's name, model, etc,
what video hardware are you working with, machine by machine.

Someone smarter than I can probably help you given these facts.

Since you use Knoppix on multiple machines, the best option would be to include the cheatcode xmodule=vesa in your /mnt-system/boot/syslinux/syslinux.cfg file - in the Label Knoppix section somewhere after the APPEND ramdisk_size=
Vesa driver will run well on any hardware and you will also have the 24 bit color depth that you were asking for in one of your previous posts
