Unhappy Knoppix 5.1 boot up


I am attempting to load/install Knoppix 5.1 from a live CD but although the CD boots it freezes at a root!tty1:/ prompt and being the newbie that I am I do not know what command this prompt is waiting for to continue the loading process.

The load stops at
Probing/loading AGP modules..............
and pressing the ENTER key gives the root!tty1:/ prompt.

Although I have sucessfully installed and use Ubuntu I would like to see what this distribution has to offer - hence the live CD boot.

Thanks - hope I am in the right place to ask this question

No problem, Knoppix is a really great tool to have in your "bag", combined with a usb-stick you can have a very small portable system, and it's great for impressing clients...

"Can I borrow your laptop for a second?"

"What the....?"




PS. I think one of the very best features Knoppix has, is the easy way to create an encrypted volume to use as settings/datastorage. Once you get it up and running, you should check it out. Then you can bring all the stuff you need in that file, and don't have to worry about other people accessing your data if you should lose the stick. (Which, unfortunately, happens sometimes...)

Might start with checking the cd. Check cheat sheet for exact boot time command. The dvd is KNOPPIX testdvd so I'd assume that KNOPPIX testcd would be the correct test. All files should pass.

had the same problem.. and solved it by modifying the /etc/init.d/xsession
this text was somewhere in the middle:

Code:
# Try to find and load an agp and drm module for this graphics card
KVER="$(uname -r)"

loadagp(){
# Kernel 2.6: Load specific AGPGART module(s)
 case "$(cat /proc/cmdline)" in *noagp*) ;; *)
  echo -n "${BLUE}Probing/Loading AGP modules...${NORMAL}"
###  modprobe agpgart >/dev/null 2>&1
# Should not be needed anymore in Kernel 2.6, but some agp bridges are still
# not detected automatically. :-( -KK
###  for i in /lib/modules/"$KVER"/kernel/drivers/char/agp/*; do
###    module="${i##*/}"; module="${module%%.*}"; modprobe ${module} >/dev/null 2>&1
###  done
  echo ""
 ;;
esac
}

# Remove unused AGP modules
unloadagp(){
i just commented out the lines that lines which now have ### on the beggining and ran that script and it worked!

(use at your own risk: i have no idea how, or why this works..)
