I had originally a NVIDIA 9800 GTX+ and my board will run 4850's and get all 3 of my monitors. I got the cards and put them in booted and of course the Xserver didn't know what to do so I went in to tty2 and started there and got back into a GUI. I went and got the driver for the card from the site and first uninstalled everything I could of the NVIDIA driver and installed the ATI driver. Now there isn't anything displaying on the screen at all. I boot and chose linux and thats it...no logon window or anything
I am running out of idea's cause Windows isn't even booting...it will blue screen cause I forgot to uninstall the NVIDIA drivers ..( at least I think). it won't make it to the log on screen either.

You did change the driver name in the xorg.conf file after replacing the Nvidia with the ATI card. Just a thought ;-)

....I think I did, but I can't actually check it since I can't get into anything...Linux will boot but nothing graphical at all comes up just the UBUNTU image and then once it loads it makes a new orange color and then nothing else comes up.

I am almost to the point of wiping everything off and doing it that way...just really don't want to since I have a lot of stuff that I don't want to do if I don't have to.

I guess you are using ubuntu in the grub menu it is I guess what push esc key to see the other option to boot or is it the up and down key can't remember. but you want to start in recovery mode it is under the default boot. this will lead you to a screen that says hey fix my graphics play with that it will use a vesa driver till you can get going. it will wipe your /etc/X11/xorg.conf file out to. then you will be using a generic driver till you get things right.

Yes I am using Grub and Ubuntu. I can get into recovery mode but thats it. I tried to reinstall the drivers and have tried a couple things to uninstall them but nothing has seemed to work. when I go to mess with the ATI Catalyst control center it says that the driver either isn't installed or not configured correctly.

Hi jus,
When you boot "normally" and get as far as a the "new orange colour" is it possible to do ctl-alt-F1 to get into a tty? Then you could see if the fglrx module is correctly installed.
How exactly did you install the ati driver? and where did you get it? was it an ubuntu package or did you get it off the ati site?

how about put a live cd in there boot your system then go copy the xorg file to yours and boot. if a live cd does not boot then you will be at the place where you have to configure the bios for the card. because all cards will run in frame buffer mode xvesa. good luck.

Better still boot into rescue mode and fix X
if you cannot deal with the CLI

After that remove all fglrx drivers (for manual installs there is a script in /usr/share/ati ), then go with radeon or fglrx (the latest)

OK I got the drivers from ATI. I removed the NVIDIA ones and now I am trying to get the ATI ones in... I have run fix x in recovery mode. I deleted and reinstalled the fglrx and did it all from CLI and no I can not get into tty2 when I "normal boot" I am having an equally hard time getting the thing to work on Windows XP pro x64 also lol.

you can have 10 different non free drivers on your system but untill the xorg.conf files calls for that driver it will not load. install driver depmod -a and configure xorg.conf to load it. good luck

I have installed depmod -a before and I receive the message that it was at the latest version. No I have attempted to change the Xorg file but I have not come across the correct one. Where is the Xorg file?

I have also used the This created a lot of .deb files and I am not sure what needs to be done with them?

Hi Jus,
1. The xorg configuration file is here:
In general, to find a file
then
2. a. First install the debs. Go to the folder where they're located and
Once they're installed then
This assumes that you have module-assistant installed. I don't know if this comes automatically with ubuntu.
Then for good measure:
If all has gone well you should stop and restart your X-server and you'll then be using the ATI proprietary driver.

There is a known bug for this issue.

Thanks I am the one you replied to in the ATI forum.
