NVIDIA version mismatch between kernel module and x windows

s|k · 03-04-2006, 04:52 PM

Hi, installed ubuntu yesterday and I replaced the NVIDIA driver today and now the x window server fails.

I have a NVIDIA 7800 GTX card.

Here's the detailed error message I received:

Code:

I took a look at FAQ at the X wiki but that didn't seem to help me.

Please help! Thank you.

You didn't upgrade the kernel module?

Not sure how you upgrade the driver in ubuntu...

I always use the nvidia driver direct from nvidia and it installs the driver and compiles a kernel module for me...

I'm curious about the kernel version... It seems to say: Linux version 2.7.12-10-386 (rather than 2.6.12-10-386 as it does earlier) There is no such thing as a 2.7 kernel. Seems odd?

But anyway, you have kernel module version 1.0.7667 and X module version 1.0.8178. Won't work until you compile the kernel module...

I typed that out from a digital image I took of the error. The 2.7 was a typo (I fixed it now). I'm new to linux and I don't know how take the log file over to the windows partition. I can't do anything on Ubuntu at the moment as all I have access to is the shell.

As for recompiling the kernel, I did take the driver directly from nvidia and and installed it as per the instructions with no error. It was after I rebooted that I had issues.

Looks like it didn't install the kernel module tho. What does the

/var/log/nvidia-installer.log

tell you?

Did the installer download a kernel module or compile one?

It compiled one. I finally got it to work. I had to chose 'no' when it asked me if I wanted the installer to allow it to run an Xorg config utility that let X run an NVIDIA driver of somekind. I didn't write it down, but I got it all to work now! I'm running 1.0-8178 now, works great!

Glad you got it working!
