First of all, Hi to everyone.

When I want to boot Knoppix 7.0.2 from a USB drive in live mode, just after the hardware recognition it give me a black screen in the monitor with the "Out of Sync" text. I know that shows up that because the synchronization of my screen is wrong but the only way I can is adding the cheat code "Knoppix nomodeset" in the boot but is only a partial solution because in the Desktop Environment I don't have Video acceleration and the resolution table in settings only reach to 1024x720 (I have a 23" LED LG and a Nvidia 9600GT)

I already try with the next cheat codes:

nomodeset (It pass the black screen but with no graphic acceleration)
screen=1920x1080 depth=24
xvrefresh=60 or vsync=60
xmodule=nv
vga=normal


Thanks for advance to anyone who can give me a hand
