[Solved] Updating Nvidia after new kernel update

kabads · 2016-12-16 13:51:33

I've just updated my laptop with

$ pacman -Syu

and everything seemed to go smoothly. However, when restarting, X won't load as the nvidia driver is complaining about no screen found. My guess is that this is because the nvidia hasn't been compiled against the new kernel.

Is there a way of uninstalling the nvidia driver and then forcing it to clean the cache before reinstalling it? I'm using the kernel from the extra repository, not the aur version.

If this doesn't work, I might be tempted to roll back to my last kernel version as that played very nicely with nvidia.

Any advice is gratefully received.

TIA

Why are you guessing instead of looking at the logs?

As long as you're using the driver in the repos, your assumption should be incorrect.

That is a log, singular. It's not even a complete one...

What does the journal say?

kabads · 2016-12-16 16:13:47

Dec 16 15:36:08 hark kernel: NVRM: API mismatch: the client has the version 375.26, but
                             NVRM: this kernel module has the version 375.20.  Please

Hmm- I've just installed the usual version of nvidia - not sure how to get the version that the kernel is expecting.

It seems that this might be the same problem that this person was having - http://funloop.org/post/2014-06-04-nvrm … match.html - doesn't mkinitcpio get triggered automatically during the update?

kabads · 2016-12-16 16:20:44

Fixed with

$ mkinitcpio -p linux

and then reboot.

Unless you have explicitly added the nvidia modules to the mkinitcpio.conf file, this should not be needed as far as I know.
To prevent this in the future you could either remove the nvidia modules from your mkinitcpio.conf (assuming you're not using modesetting anyway) or configure a hook for pacman to run `mkinitcpio -p linux` on driver update.
The wiki has a hook for that here: https://wiki.archlinux.org/index.php/NVIDIA#Pacman_hook
