I have no problem with v4 but when I boot with V5 I choses settings my Matrox 450 video card cannot display. Anyone know of a cheat to solve this problem.

You can try the following cheat codes:

vga=0 or vga=normal

screen=1280x1024
Use specified Screen resolution for X

xvrefresh=60 or vsync=60
Use 60 Hz vertical refresh rate for X

xhrefresh=80 or hsync=80
Use 80 kHz horizontal refresh rate for X

xserver=XFree86|XF86_SVGA
Use specified X-Server

xmodule=ati|radeon|fbdev|vesa|savage|s3|nv|i810|mg a|svga|tseng
Use specified XFree4-Module

For matrox the module should be MGA.
For other setting you can try Knoppix 4, look into files at /etc/X11 (something called xf86config or similar).

If all failed, try to boot into console mode:
Knoppix 2

After reaching the prompt, try one of the following commands:
xf86conf, xf86cfg, xorgconf or xorgcfg

Setup using Matrox driver or SVGA.

Use the following command to start X-Windows:
xinit
