Hi again. This thread follows a previous of mine, where I as struggling to find a suitable driver for my video card, a GF108GLM.

Now I've found one, namely nvidia-driver-340.102, I run into another issue: module panic.
/var/log/messages:

I have found a similar topic and applied the patch mentioned by ChrisJumper but it doesn't help.

Thanks in advance for any hint/suggestion.

I use a vanilla kernel myself (LTS 4.4.78 ), if you cannot adapt the nvidia-drivers to your kernel, what if you adapt the kernel to the drivers?
https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.4.86.tar.xz

I know you need download/build... but it would help you at end: answering to "do i need a patch for my kernel?"

Thanks for the suggestion, krinn. I'm currently trying Manjaro's kernel config, 4.9 kernel (EDIT: not 4.4, where was my mind!) I'll try the vanilla one once I'm done testing this one.

But what about emerge =vanilla-sources-4.4 instead?

I've got help from nVidia forums in past, the developers know best: https://devtalk.nvidia.com/default/board/98/linux/

As a minor point, as written your command (1) asks for the original 4.4 series release (from Linus), not one of the later 4.4 series stable releases (from Greg KH, or whoever might take over that task for the 4.4 line); and (2) fails in a current Portage tree because only very recent releases from each series are available. I have no comment on the underlying idea of using Portage to fetch/install sources for a 4.4-series stable kernel.

Thanks for your insights Hu. My bad, my current version of portage indeed reports vanilla-sources-83, not *-86. I don't why I thought I read *-86. I'm confused.

Wait!

There's something interesting going on now! I have compiled my gentoo kernel with MANJARO's 4.9 kernel config — it's powered by Nouveau. Ok, it took 2 full hours and there are gazillions of drivers I don't need but now my laptop doesn't freeze anymore when I resume from hibernate. Nor do I have a black screen after resuming from suspend!

This is definitely great news as it simply means I was not clever enough to compile a working kernel on my own with Nouveau. I'd happily give up on nVidia if I can make Nouveau work like in Arch/Manjaro.

My question now is: as I really have no idea what and where I messed up in my kernel config, is there a set of recommendation as to compiling a working kernel with Nouveau, i.e. suspend and hibernate?

Well, what you can do, is copy manjaro kernel's config over and gradually trim down the excess crud. By transfering it over, you having a starting point for a working kernel, and can work on removing what you don't need. One thing I would recommend you do, is first build manjaro's config as is on your system and make sure it works on gentoo (so you know it's the kernel specifically, and not something else). Then go back and recompile it, slowly removing some the the un-needed parts (I say slowly, so you can help narrow down the critical parts).

Well, I did exactly that but in the hope there's a more straightforward way. Thanks for confirming my intuition then :-) . What I can tell is that Manjaro's kernel config is fully functional under Gentoo. What I did is copy the kernel config (approximately the same build number 4.9.34 for Gentoo, 4.9.39 for Manjaro) and run
Code:
make oldconfig

The only questions I was asked for were about Gentoo support, which are part of Gentoo patchset I presume.

There's just one problem that's still present: when I close the lid while X is active and then reopen it, the screen kind of powers on briefly (so I can see the screensaver for one-two seconds) then turns black. I still can switch to a text console with Ctrl+Alt+F1, for instance. But as soon as I get back to X (tty7) the screen is black, as if it were powered off. However there's no more freeze resuming from hibernate — so far at least.

You might find the kernel build targets localmodconfig or localyesconfig useful. Those are documented as building a kernel that has everything you currently loaded, but dropping all the features you do not have loaded. If your loaded module set is sufficient for the machine to work, then the generated configuration should also be sufficient. It might not be the smallest possible sufficient configuration, but it will get you close without extensive trial and error.

Thanks Hu, that is *exactly* what I was about to ask for. I didn't know such thing existed as I've been sticking to what I know about building kernel since 2004... well, not particularly clever for a Gentoo'er I admit but... well :oops: .
