[Solved]GTX 960M with bumblebee not working [NVidia drivers]

[Marandil]

Hi all

I have a Lenovo Y50-70 laptop with i7-4720HQ and GTX 960M and I'm trying to get the Optimus technology running.

I have the following nvidia- and bumblebee-related packages installed:

I'm using kernel version 4.1.0-1 from Debian testing repository, but I'm also testing all solutions on the default 3.16.0-4.

When I try to run optirun, I get the following error:

Some weird things I noticed:

nvidia-detect by default does not detect the GPU, even though it's clearly there in lsmod. After specifying the PCI, it claims that it's only supported by unsupported legacy drivers or that it is not YET supported (though I think this comes from Big Endian vs Little Endian naming of PCI lines or sth):

Uh oh. Your card is not supported by any driver version up to 340.76.
A newer driver may add support for your card.
Newer driver releases may be available in backports.

Uh oh. Your card is only supported by the 71.86 legacy drivers series, which is not in any current Debian suite.

Any Ideas?

Hello Marandil and welcome to Mint,
Nvidia drivers can be a pain, but most of the time you can get them working.

Nvidia says there better driver 346 you may want to give that one try.
I'm not familar enough with bumblebee to give you advice on that.
good luck.

[Marandil]

I think I solved it at some point, though I'm not entirely sure how, so I'll explain in detail what I have done (so if anyone else has a similar problem, he can try it himself)

I noticed, that - as kc1di pointed out - the drivers available in the repository are rather outdated, and since 9xxM series is (I think) the latest NVidia series (at the time of writing), it's probably not yet supported by those drivers. I went to NVidia for the drivers, but since everyone discourages taking their "Linux installer" (I also had an unpleasant experience with that) I googled for the version and found a package in the Debian experimental repository:
https://packages.debian.org/experimenta ... dia-driver

I decided to upgrade the drivers from the repo, I added "deb http://ftp.de.debian.org/debian experimental main contrib non-free" to my sources.list.d/... and run:

Code: Select all

apt update
apt upgrade nvidia-driver
# press yes, upgrade only drivers and dependencies to avoid unnecessary "experimental" packages

Next, I commented out the line with experimental from my sources and run apt update again (to avoid using the experimental packages in the foreseeable future).

Now, the optirun -vv glxgears was failing with yet another error: "Could not load GPU driver". I googled for that error and found this: https://github.com/Bumblebee-Project/Bu ... issues/604 issue on bumblebee github.
After issuing:

Code: Select all

modprobe nvidia-current nvidia-uvm

The optirun did actually run, but only once. After closing the window, the modules were unloaded and it wouldn't work again. As suggested in the issue, I also run:

Code: Select all

depmod -a

Though I'm not entirely sure whether this helped or not. Finally, I went back to bumblebee configuration files, and noticed that apparently, in my /etc/bumblebee/bumblebee.conf I had "KernelModule=nvidia" while I should have had "KernelModule=nvidia-current".
For now, it did the trick.

So, summing up:
1. Updated drivers to the ones in experimental
2. Manually loaded the kernel modules:

Code: Select all

modprobe nvidia-current nvidia-uvm
depmod -a

3. Checked whether in /etc/bumblebee/bumblebee.conf, "KernelModule=nvidia-current"

[by the way, 80% of solutions found on the web actually tells you to change from KernelModule=nvidia-current to KernelModule=nvidia. Check that via find /lib/modules/$(uname -r) -name 'nvidia*.ko*]

One more note: optirun works after reboot, so either the modprobe was unnecessary or just needed one-time

Glad you sorted it out

I am waging this same battle. I have an asus ux-501 with the same GTX 960M nvidia card. I agree the problem seems to be the need for newer drivers.

I first tried regular mint (ubuntu-based) and got the optimus working on nvidia-352. glxgears gave ~20000 fps.

I've now installed LMDE2, added the experimental deb, and installed bumblebee-nvidia and primus. I'm now getting the "failed to set DRM interface" error.

I tried adding the Screen section to xorg.conf.nvidia, and I specified nvidia driver in bumblebee.conf but I still get the same error.

When i look in /proc/driver/nvidia/version it says that I've got the newer 352.30 nvidia driver that worked in the ubuntu distro. But in that case I blacklisted and uninstalled the nouveau bits. Is that necessary here?

Im on vacation - this is all im doing right now. I take meticulous notes on what I do, so if I get this working I'll post all I have. I've spent the last three days looking for solutions. Any help would be great. This is a new system, I'm happy to do a fresh install for any new set of steps.

Thanks.

HI flynx,

If the nouveau driver is installed you need to blacklist it. it will interfere with any nvidia drivers.
If that is not the case you should start a new thread on this problem.

Hi guys,

I have the same notebook, y50-70 and the same gpu but I haven't been able to install the driver as suggested.
My sources.list looks like this:

Code: Select all

/etc/apt/sources.list.d/official-package-repositories.list 
deb http://ftp.de.debian.org/debian experimental main contrib non-free

deb http://packages.linuxmint.com betsy main upstream import

deb http://ftp.us.debian.org/debian jessie main contrib non-free
deb http://ftp.us.debian.org/debian jessie-updates main contrib non-free
deb http://security.debian.org jessie/updates main contrib non-free

deb http://www.deb-multimedia.org jessie main non-free

deb http://extra.linuxmint.com betsy main

and the error I get is:

Code: Select all

apt install nvidia-driver=352.63-1

I cannot do a apt upgrade since I've removed the original nvidia-driver (340). Anyhow, I've tried to also have installed the 340 and do an upgrade but the problem is the same.

Any ideas?

P.S. I've checked for held packages and I have none.
Also, tried to install the driver from the nvidia site but bumblebee does not work properly, I get the "/dev/dri/card0: failed to set DRM interface version 1.4: Permission denied" error; I've tried to add the "Screen" section to bumblebee.conf, also uncomment the BusID section, changed the driver name from nvidia-current to nvidia but nothing helped.

Thank you!

[emmerich]

I finally managed to install the whole experimental bunch (priorities/pinning, etc.) but the problem manifests in the same way:

Code: Select all

/dev/dri/card0: failed to set DRM interface version 1.4: Permission denied

Tried different configurations of xorg.nvidia.conf (with BUS un/commented, with the "Screen" section and without) but no joy.

Any other ideas?

[emmerich]

Well, I've finally got it running, it was a true saga.

Here it is:

1. Had to install the nvidia driver (352 currently) from debian experimental (have fun with changing package priority/pinning)
2. Had to add the 'Section "Screen"' like described here https://wiki.debian.org/Bumblebee to the xorg.config.nvidia
3. Had to downgrade libdrm2 & libdrm-intel1 (both amd64 and i386) to 2.4.56 -- remember to apt-mark hold 'em
4. Had to change the kparam in /etc/default/grub to rcutree.rcu_idle_gp_delay=1 then update-grub
5. Reboot the bucket

Finally I've run a small benchmark comparing the performance with a W10 installation; seems that on W10 I get ~2fps more, of course the drivers 352 != 359

I just wanted to thank you for describing the installation procedure - I was just about to give up when I found it, made my day.
I had to modify the /etc/bumblebee.conf LibraryPath for the nvidia drivers in order to get it work with wine. Also forgot to install some of the nvidia driver/gl[x] libraries for the i386-architecture at first, but now everything works (tried just for fun: Anno 1404 in max settings runs smoothly, and when nothing is run via optirun, power consumption drops from ~60W to ~16W).

So thanks again, the last few days were a rather painful experience.
