No GUI after swapping an Nvida card for an Ati card

[DocEsq]

I am running LinuxMint 10 on a dual boot system. I took out an old Nvida video card for a newer Ati Video card. When I start Mint it puts me in command line and even "startx" does not work. I have figured out that I need to uninstall the Nvida drivers first and then have Mint install the drivers for Ati.

So how do I uninstall the Nvida drivers from the command line?
After that do I just let Mint reboot do I first need to install the Ati drivers?

I do have the old Nvida card so would it be easier to just put it back and make whatever changes are needed before putting the Ati card back?

Is Jockey the right program for me to be using and if so what are the command lines I need.

Can I correct this using the Live CD?

Just as an FYI my XP works fine so the card is not defective.

Any help would be appreciated.

Thanks.

these commands will uninstall the drivers from nvidia and ati proprietary, and you reconfigure the x server to start with the free ati drivers.
Then, as on the desktop, go to additional drivers, and install proprietary ati drivers if you want.

Code: Select all

sudo apt-get remove --purge nvidia-glx
sudo apt-get remove --purge xorg-driver-fglrx fglrx*
sudo apt-get install xserver-xorg-video-radeon
sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg

Thanks for the assistance linmint777 but I have run into some problems.
I first confused a "1" with a "l" so of course got no where.

When I made the correction I then was getting after

Code: Select all

sudo apt-get install xserver-xorg-video-radeon

the error messages that look like something " 0.67 No irq handler for vector (irg-1)"

I kept getting this message also for the command

Code: Select all

sudo dpkg-reconfigure xserver-xorg

.

So what did I do wrong and anyone know how to correct it?

Is a older bug with ATI cards drivers on some video chipsets, to correct:



1.

Code: Select all

sudo nano /etc/default/grub

2. change this line:

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

for this:

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi,noaer"

3.

Code: Select all

sudo update-grub

[DocEsq]

From the command prompt I enter

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

but when I try to go to edit

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

by moving the cursor, it seems to time out and it disappears with some new stuff on the screen.

So how do I get the cursor over to the line in time so that I can edit?

Thanks

More easy way:

1.- Boot from a live-cd.
2.- Mount the LM10 installed.
3.- Open nautilus (file manager) as root with:

Code: Select all

sudo nautilus

4.- Looks for this file "/etc/default/grub" from nautilus as root in your LM10 installed.
5.- Right click --> open with gedit (text editor).
6.- Look for this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
7.- Add this text to the line:
pci=nomsi,noaer
Should be so:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi,noaer"
8.- Save the file and close gedit.
9.- Reboot without live-cd.

Thanks for the help. I have not had a chance to try it yet as my CD/DVD drive appears to have died. Once I install the new one I will give it a go.

Found a spare CD drive that I plugged in. When I tried to use the Live CD I could not get to a GUI. I next placed my old Nvida AGP Card in and Mint booted up no problem.
I am not sure if the problem was the ATI PCIx card since I was able to boot into XP without any problem. The only other thing I can think of was that there is a problem with my Motherboard.

Thanks for all of the help but for now I will use my old card as it does fit my needs.
