Titel: Accidentally change Video Drivers, Help

Hi, I accidentally changed the video drivers on Control Center, now I have a black screen each time I try to logon. My kanotix was perfectly running fgrlx driver and change it to Ati, then all whent black. No luck trying with other options. Can some one help me??
I'm a linux newbe so please make it very easy to understand if I have to do it with the live cd (I have it).
Thanks a lot, any help wil be great!

normaly knxcc (kanotix control center should let you go back to fglrx.
if not, go to /etc/X11 and look for xorg.conf. there should be a few, like xorg.1st or xorg.xxxx.save (xxxx resambling dates) rename xorg.conf to xorg.old and one of the saved ones with a current date to xorg.conf and restart x.

Thanks Devil but my problem is that I can't login. So I can't do anything. After booting Kanotix I don't even have the chance to put my password.
Any idea?
Thanks

Can you boot to a shell login prompt by appending "init 3" in the line with grub boot commands?

You could also boot your system off the Kanotix cd and try reviewing and/or editing /etc/X11/xorg.conf from there.

Yes I can boot to a shell login prompt (init 3). What are the exact commands to change file names?
Can you please type what I should type in the shell. Remember I'm a window guy.
Thanks devil.

as root:

Code:

ls -l /etc/X11

that will show you the contents of /etc/X11. look at the files named xorg.conf.
pick one with a current date like:

Code:

xorg.conf-06.08.06-19:28.save

now do:

Code:

cd /etc/X11

mv xorg.conf xorg.old

mv xorg.conf-06.08.06-19:28.save xorg.conf

now you have renamed the saved xorg.conf (xorg.conf-06.08.06-19:28.save)
to xorg.conf. now you can try to enter X with that by typing:

Code:

init 5

that should bring you back to X and kde
maybe you have to reinstall your fglrx.
to find out, if it is still installed, do:

Code:

glxinfo | grep direct

the answer should be "yes"
if not, reinstall fglrx in kanotix control center.

Thanks again devil. Well I change both files but I could'nt get back to init 5. I get the following message:
Not starting x display manager (xdm); it is not the default display manager.
How do I fix that now?
Thanks for helping

log in as user and type "startx"

It will tell you more usefull errors. xdm is not the default manger it is kdm so that error is natural.

Thanks jakiebrown. I get the following errors:

(EE): Failed to load module "speedo" (Module does not exist)
(EE): Failed to load module "fglrx" (Module does not exist)
(EE): No drivers available
Fatal Server error: No screens found
X10: Fatal error 104 (conection reset by peer) on X server ":0.0"
After 0 request (0 know processed) with 0 events remaining.

I think I have more than one problem!! Why?
What can I do?
Thanks for any help.

It is all the same error. Just re-run the install ati driver script and you should be up and running.

Should be something like install-fglrx (or maybe ati) ..... (just press tab to auto complete the name)

Do this as root.
