Need to remove Nvidia driver to start over

[caprus]

I just updated the kernel then tried to update the Nvidia driver too (the "hard" way, as I have many times, no help needed with how to do that), but I carelessly screwed up the Nvidia driver installation with a simple typo that I didn't spot 'til it was too late.

How do I remove the Nvidia driver, so I can start over? (CLI please)

Thanx

If you were installing the driver the hard way, I can't think what typo you got wrong? There is only the Nvidia package name to type and TAB auto completes that anyway.
Just re-install it

[caprus]

I simply typed -q instead of -K

Now Sax2 will not run with 0=nvidia, and attempts to reinstall result in "ERROR: installation has failed"

[caf4926]

Re-install from level 3 boot.
Never fails for me

Here is my how to:

Alright so here is how to install the nvidia driver manually, in case the one in the repo doesn't work or u just want to use the latest.
Go to Yast>Software>Software Management
Search for and install if you don't have these:

make
gcc
kernel-source

Now download the latest Nvidia driver:
Place the file in your /home/username
Now restart and at the boot screen, pause the boot by moving the down button, then move back up and clear any text in the boot arguments by holding backspace. Then just type the number: 3

At the login
Type "root" then enter and then your root password and press enter.
now type
cd /home/username
*Now remember you can use the {TAB} key to auto complete
so type:
sh NVIDIA{TAB}
and the whole file name should auto complete
eg: sh NVIDIA-Linux-x86-180.14.09-pkg1.run
Follow the installer and let it compile the kernel module for you.
Say Yes to everything
Use TAB to move around
reboot

Sorry to say that's exactly what I've been doing, several times in fact. Interesting though that the precise errors received when running Sax2 are not always the same. That doesn't make sense, butt there it is.
Anyhow, I just tried two more times. The second time the error message from Sax2 pointed to /var/log/SaX.log. Most of that file appears unremarkable (to my untrained eyes) except for the line 4 below "(II) Loading /usr/lib64/xorg/modules//dirivers/nvidia_drv.so" that says "FATAL: error inserting nvidia (/lib/modules.2.6.27.29-0.1-default/weak-updates/updates/nvidia.ko): No such device"

Does that offer any clues?

I'm running now on 0=nv, but I'd really like to get back to using the proprietory Nvidia drivers as I had been for the past 2 years or so. Can I remove the faulty installation and start over, or failing that can I roll back to the previous version somehow?

[caf4926]

Try rolling back all the kernel packages to the previous versions and re-install the driver, see what you get.

If that works, you could then try going forward again.

Other options:
Backup xorg.conf
Then try starting a new one

Solved:

(just the high points)

1. uninstalled new Nvidia driver using #sh NVIDIA-Linux-x86_64-185.18.36-pkg2.run --uninstall

2. installed earlier driver (version that worked ok before) using #sh NVIDIA-Linux-x86_64-185.18.31-pkg2.run

no improvement

3. uninstalled new Nvidia driver using #sh NVIDIA-Linux-x86_64-185.18.31-pkg2.run --uninstall

4. rolled back kernel to earlier version (with yast)

5. installed newest Nvidia driver using #sh NVIDIA-Linux-x86_64-185.18.36-pkg2.run

result: New driver now installs and Sax2 configures successfully.

conclusion: The new kernel update (2.6.27.26-0.1.1) did not solve the problem I thought it would and literally prevented the installation and configuration of proprietary Nvidia drivers. It has serious flaws, and is not ready for prime time.

Thanx caf4926 !

Nicely sorted. Well done!

There's a typo in my entry #8 above that could be rather confusing if not repaired. The first word of line 5 should be "installed" not "uninstalled".

Perhaps a moderator could correct this error for me? Thanx.
