must rmmod nvidia & modprobe nvidia to start X

[Zach]

Hi,

Thanks for the responses.

Yes it is getting loaded at startup, as confirmed by lsmod.  In fact,
the nvidia module was already loaded, it was only after a couple of
hours of troubleshooting that I discovered rmmoding it and reloading
it would make a difference.

I was getting this in syslog:
Feb  7 21:44:09 kessel kernel: [   32.020185] NVRM: loading NVIDIA
Linux x86 Kernel Module  1.0-7185  Mon Apr  2 18:29:54 PDT 2007
Feb  7 21:44:12 kessel kernel: [   40.886353] NVRM: RM/client version mismatch!!
Feb  7 21:44:12 kessel kernel: [   40.886362] NVRM:    aborting to
avoid catastrophe!

And I was getting this in Xorg.0.log:
(EE) NVIDIA(0): Failed to initialize the NVIDIA kernel module! Please ensure
(EE) NVIDIA(0):     that there is a supported NVIDIA GPU in this system, and
(EE) NVIDIA(0):     that the NVIDIA device files have been created properly.
(EE) NVIDIA(0):     Please consult the NVIDIA README for details.
(EE) NVIDIA(0):  *** Aborting ***


As I mentioned, lsmod did confirm that the nvidia kernel module was
loaded, and removing and reinserting it allows X to work.

I have tried all combinations of removing, purging, reinstalling,
nvidia-glx, nvidia-glx-new, linux-restricted-modules.  I have used the
restricted drivers manager, and I have done it manually (installing
the packages using apt).

Some background:  This happened when I swapped out my old (Ti 4200)
Nvidia card for a slightly less old (FX 5200) card.  Before swapping
the hardware, I disabled the proprietary driver using the restricted
drivers manager (causing 'nv' to be re-enabled).  Then after swapping
out the hardware, I re-ran the restricted drivers manager, which
detected my 5-series card and appropriately install nvidia-glx-new.
Then badness ensued.

Thanks in advance.
