NVIDIA Corporation GF108M - HP Pavillion DV4 - Nothing works? #761

Open LordAmit opened 8 years ago

LordAmit commented 8 years ago

Edit: Solution Found - Tweak edition We worked out a solution. In case tl;dr, please check this link: https://github.com/Bumblebee-Project/Bumblebee/issues/761#issuecomment-219561042

Hi,

This is a few years old Optimus enabled graphics card. I was able to use it using bumblebee a few years ago as well, but in later versions of Ubuntu I have never been able to. I have tried setting it up using information from askubuntu, from ubuntu, from the various issues here, from different blogs. Nothing worked. Every single time I tried setting the latest nvidia driver (last attempt - last night 361) and rebooted, the login screen started flickering, pressing Alt + Ctrl + F1 to access terminal didn't work, and I had to get in Ubuntu advanced recovery mode to purge everything and back to square one. Before that, I tried editing bumblebee.conf and xorg.conf.nvidia. I tried making the bumblebee daemon work, but it kept failing at nvidia_uvm, or nvidia, or something else. I am really sorry if all these sound a bit incoherent.

Therefore, please guide me what I need to do. Here is my config: 

lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 630M] (rev a1)

I am using Ubuntu Gnome 16.04 LTS - with GDM3 Display Manager.

Laptop Details: http://www.ubuntu.com/certification/hardware/201209-11722/

Please, let me know if you need any other information. I will provide any information required to solve this.

Thank you in advance.

Yes, that's related to the missing modprobe. Try to link it manually:

sudo ln -s /lib/nvidia-361/modprobe.conf /etc/modprobe.d/nvidia-tmp.conf sudo depmod

And set KernelDriver=nvidia and try again?

LordAmit commented 8 years ago

Went through 

sudo ln -s /lib/nvidia-361/modprobe.conf /etc/modprobe.d/nvidia-tmp.conf
sudo depmod

then, 

[driver-nvidia]
# Module name to load, defaults to Driver if empty or unset
KernelDriver=nvidia
sudo systemctl restart bumblebeed

optirun now works with glxgears.

$ cat /proc/acpi/bbswitch
0000:01:00.0 ON
amit@amit-laptop:~$ lsmod | grep nvidia
nvidia_modeset        745472  0

bluca commented 8 years ago

Ok, so what is missing now is handling nvidia-modeset. I'm from the phone so can't be too precise, but you should have /etc/modprobe.d/bumblebee.conf and at the bottom a remove rule that says to remove nvidia-uvm when removing nvidia. Right after nvidia-uvm add nvidia-modeset, separated by a single space and try again

LordAmit commented 8 years ago

It has a line like this:

remove nvidia rmmod nvidia-uvm nvidia

Should I make it like this?

remove nvidia rmmod nvidia-uvm nvidia add nvidia-modeset

?

bluca commented 8 years ago

Without add

bluca commented 8 years ago

And after nvidia-uvm

LordAmit commented 8 years ago 
remove nvidia rmmod nvidia-uvm nvidia-modeset nvidia

Done. is this ok now? What do I do after saving?

sudo depmod And the try again

bluca commented 8 years ago

What's the output of sudo modprobe -v -r nvidia

LordAmit commented 8 years ago

Nothing. It outputs absolutely nothing after sudo modprobe -v -r nvidia

That's... weird. The rule is there. Why is it ignoring it?

Try:

sudo modprobe -v -v -v -r nvidia

You are the expert here, boss. You know what's going around. Am merely following your lead :smile:

bluca commented 8 years ago

What if you make the rule you changed before in /etc/modprobe.d/bumblebee.conf like this:

remove nvidia rmmod nvidia_361-uvm nvidia_361-modeset nvidia

LordAmit commented 8 years ago

changed the line to

# remove nvidia rmmod nvidia-uvm nvidia-modeset nvidia
remove nvidia rmmod nvidia_361-uvm nvidia_361-modeset nvidia

then

Sigh. Ok, I can reproduce this locally - this is a problem with Ubuntu's modprobe aliases. I will try to investigate locally and see what we can do.

I have absolutely no idea what's going on and what I am doing, btw. Want to give me a brief?

bluca commented 8 years ago

Unloading the kernel module does not work. This is because it's now split in 2 (and 3 in 364 and up) - nvidia and nvidia-modeset. rmmod nvidia won't work if there's something depending on it still loaded, like nvidia-modeset. In Debian we solve this problem with modprobe rules. You can define complicated rules that are followed when you run modprobe. For example, in Debian, when you do modprobe -r nvidia it will also unload automatically all other nvidia-* modules. This does not happen on Ubuntu, and that's the problem.

I was trying to find a combination that works for Ubuntu. I will try locally and see where I can get. I'll report back in a while. Thanks for the help!

To unload the module and turn the card off (to save power), a combination of these should work:

sudo modprobe -r nvidia-modeset sudo modprobe -r nvidia

or

sudo rmmod nvidia_modeset sudo rmmod nvidia

and finally, when lsmod | grep nvidia is empty,

sudo tee /proc/acpi/bbswitch <<<OFF

LordAmit commented 8 years ago

I see. Looks like only rmmod works.

sudo modprobe -r nvidia-modeset
amit@amit-laptop:/etc/modprobe.d$ sudo modprobe -r nvidia
amit@amit-laptop:/etc/modprobe.d$ lsmod | grep nvidia
nvidia_modeset        745472  0
nvidia              10076160  1 nvidia_modeset
drm                   360448  12 i915,drm_kms_helper,nvidia
amit@amit-laptop:/etc/modprobe.d$ sudo rmmod nvidia_modeset 
amit@amit-laptop:/etc/modprobe.d$ sudo rmmod nvidia 
amit@amit-laptop:/etc/modprobe.d$ lsmod | grep nvidia
amit@amit-laptop:/etc/modprobe.d$ sudo tee /proc/acpi/bbswitch <<<OFF
OFF
amit@amit-laptop:/etc/modprobe.d$ cat /proc/acpi/bbswitch
0000:01:00.0 OFF

I should make a short shell script to automate these.

LordAmit commented 8 years ago

BTW, I am seriously considering moving to Debian. I guess we are both taking a break until you come up with something, @bluca .

Once again, thank you for the patience and guidance. I really, really am grateful. :smile:

bluca commented 8 years ago

oh wait a sec. Try with this in /etc/modprobe.d/bumblebee.conf:

remove nvidia rmmod nvidia_uvm nvidia_modeset nvidia

LordAmit commented 8 years ago

should not I revert the rmmod I just did? as well as the bbswitch part? What do I do after modification?

bluca commented 8 years ago

No that will be done automatically by bumblebee

LordAmit commented 8 years ago

No it does not?

since optirun is not working anymore, should I revert back to the previous lines in bumblebee.conf in modprobe.d?

bluca commented 8 years ago

Yes go for it.

LordAmit commented 8 years ago

Still does not work. Optirun not running.

bluca commented 8 years ago

the line should be:

remove nvidia rmmod nvidia-uvm nvidia

LordAmit commented 8 years ago

Nope, nothing even after changing the line to the one you mentioned above. I think I should've mentioned this earlier: 

lsmod | grep nvidia

Shows nothing. bbswitch is ON.

Try with disabling the card before: sudo tee /proc/acpi/bbswitch <<<OFF

I don't know anymore what is broken with these modprobe aliases. Again, I'll try locally. Meanwhile, you can get around it by setting KernelDriver=nvidia-361 in /etc/bumblebee/bumblebee.conf and turning the card off manually.

Alright then. I will get some sleep. Last night's lack of sleep took a toll on me >.>

Script for removing modules related to nvidia and turning off bbswitch:

#!/bin/bash
sudo rmmod nvidia_modeset
sudo modprobe -r nvidia-modeset
sudo modprobe -r nvidia
sudo rmmod nvidia_uvm
sudo modprobe -r nvidia
sudo rmmod nvidia
sudo tee /proc/acpi/bbswitch <<<OFF

@bluca - let me know if you need any additional information - BTW. Keep me updated please.

Will do, thanks for testing

In previous versions, Ubuntu used Upstart which has some auto-detection for the driver (see debian/bumblebee.bumblebeed.upstart or /etc/init/bumblebee.conf). The init.d shell script does not seem to perform auto-detection which might result in surprises upon updating.

We precisely avoided modprobe -r nvidia in the past because it did not handle aliases well (modprobe nvidia-current or modprobe nvidia-304 would make module nvidia appear in lsmod and /proc/modules). I thought that this was fixed in recent kmod, if it is not, then the libkmod patch must be updated I guess.

Hopefully when this is merged this problem will go away: https://github.com/Bumblebee-Project/Bumblebee/pull/762

On Debian, modprobe -r nvidia works just fine (even with the new kernel modules), because we ship a working modprobe conf file. That is sadly not the case on Ubuntu, where they either are broken or aren't even configured and linked in /etc/modprobe.d.

Umm, hello. Today probably @bluca pushed an update to the testing repository. here is what happened.
