[solved] Not able to downgrade nvidia

I'm trying to downgrade nvidia 340xx to 304xx. I have some problems with 340, so even though my card should support 340, I'd like to try 304.

But pacman throws dependencies errors:

$ sudo pacman -Sy lib32-nvidia-304xx-libgl lib32-nvidia-304xx-utils lib32-opencl-nvidia-304xx nvidia-304xx nvidia-304xx-libgl nvidia-304xx-utils opencl-nvidia-304xx

error: failed to prepare transaction (could not satisfy dependencies)
:: lib32-nvidia-340xx-utils: requires nvidia-340xx-utils
:: nvidia-340xx: requires nvidia-340xx-utils=340.96

It says lib32-nvidia-340xx-utils has a requirement, but I don't need 340 to have anything because I'm downgrading it anyway. It feels catch22y.

How do I make that downgrade?

First of all, never -Sy $package: that will just end badly.

Remove the 340 packages and then -Syu 304 ones...

Re: [solved] Not able to downgrade nvidia

I'll keep that upgrade  on mind.

However removing 340 failed at dep checks:

$ sudo pacman -R lib32-nvidia-340xx-libgl lib32-nvidia-340xx-utils lib32-opencl-nvidia-340xx nvidia-340xx nvidia-340xx-libgl nvidia-340xx-utils opencl-nvidia-340xx
checking dependencies...

should I force it with -Rf, or is it a not good idea?

Re: [solved] Not able to downgrade nvidia

Don't force it.

pacman -R nvidia-340xx nvidia-340xx-libgl && pacman -S nvidia-304xx nvidia-304xx-libgl

Re: [solved] Not able to downgrade nvidia

But I cannot downgrade otherwise. It fails at depchecks. See my previous post.

Re: [solved] Not able to downgrade nvidia

I can do -Rsc, but it removes a million packages with it which I would like to keep. Especially if they don't technically need to be removed, because I want to install 304 immediately after.

So the question comes back to why can't I simply -Syu as per OP and why does the pacman nags about dependencies that are moot?

edit: ok, I've noticed -Rdd, but that feels awfully dirty leaving packages completely without dependencies, even temporarily. Feels worse than -Sy alone.

Re: [solved] Not able to downgrade nvidia

in no way is this worse than -Sy, the assumption is that you immediately replace them with the correct libGL implementations you want to use. The nag is an order thing, look here for how to do it the "right" way

Re: [solved] Not able to downgrade nvidia

ok, that explains it, I guess. Thanks.

Unfortunatelly 304 failed to get into the loginmanager and I had to go back to 340, but that is another issue.
