I'm running 14.04 on an ASUS UX303UB which features that ever so troublesome dual GPU thingy, with 'Sky Lake Integrated Graphics' for discrete graphics and 'GM108M [GeForce 940M]' for performance graphics.

I've had a very similar laptop, UX303LN, which featured the very same graphics setup but it used a Intel Broadwell architecture where this new one features a Sky Lake architecture.

Having read a bit on the subject, it seems these new architecture wasn't supported before linux 4.3, and was now improved on 4.4.

I'm now running the latest possible kernel (Linux ux303 4.4.4-040404-generic #201603031931 SMP Fri Mar 4 00:34:16 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux), and installed the latest nvidia graphics 352 (tried both the 352 and 352-updates).

But nvidia-prime won't list any of the GPUs, I know I'm stuck on the Intel discrete GPU (because of performance). Running prime-select query simply returns unknown, forcing prime-select nvidia gives me:

   Error: alternatives are not set up properly
   Error: nvidia mode can't be enabled

I am completly stuck on this, have tried a number of different things (so many I can't remember which), I was really hoping the 4.4 kernel would get this to work, but no luck. I was using 3.19 kernel before, and I could see the GPUs on nvidia-prime (just couldn't select the NVIDIA card).

Any help, ideas, comments, or more information you can give, or require, please feel free.

  • I have the exact same hardware and I'm trying 16.04 right now. The problem is after installing nvidia-361.42 and rebooting I get stuck in a login loop. Did you get the nvidia drivers to work somehow? – Lars Nyström Apr 23 '16 at 18:50
  • Aha, I used the nvidia ppa and installed nvidia-364 in the terminal and it asked me to disable secure boot. I did that, and then I could log in. I'm not sure if the ppa-package solved this for me, or if it was that I installed it in the terminal instead of using the "Additional drivers" GUI. – Lars Nyström Apr 23 '16 at 20:03
  • What kernel are you using? – Pedro Rodrigues May 18 '16 at 10:18
  • Actually, it turned out that it only worked sporadically. But it was the default kernel from the first 16.04 release. I might try again when they release 16.04.1, since they usually work out some kinks until then. I'm sorry that I got your hopes up. – Lars Nyström May 19 '16 at 7:49

Had the same problem with asus 303ub. The solution is to disable secure boot in bios(usually under "security tab"), not sure why it works this way and at the first boot after disabling it I got a "black screen" but it went OK after another reboot. For the reference: Asus 303ub, Nvidia 940m, Ubuntu 16.04,

# dpkg -l | grep nvidia

  • Are you happy with the Nvidia GPU in your laptop? Would you take your laptop with or without it? I am considering the same GPU or Intel's integrated for Ubuntu. – Léo Léopold Hertz 준영 Aug 21 '16 at 11:12
  • Have you tried to switching: prime-select nvidia and rebooting? I am now having some issues with newer versions... – Juan Leni Nov 1 '16 at 18:45

I managed to get it to work following the first part of this link: https://devtalk.nvidia.com/default/topic/936429/-solved-tensorflow-with-gpu-in-anaconda-env-ubuntu-16-04-cuda-7-5-cudnn-/

$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt-get update
$ sudo ubuntu-drivers autoinstall
$ sudo reboot

Later:
> Software & Updates > Additional Drivers
Change from nvidia-364 (open source) to "Using NVIDIA - version 361.42 from nvidia-361 (proprietary)

A second issue I had with 16.04 was that suspending/resuming was not working (i.e. Close lid or FnF1 in Asus UX303UB). The only way I found to fix it and at the same time get the nvidia drivers to work was to use Kernel 4.5.4:

$ wget kernel.ubuntu.com/~kernel-ppa/mainline/v4.5.4-yakkety/linux-headers-4.5.4-040504_4.5.4-040504.201605120823_all.deb
$ wget kernel.ubuntu.com/~kernel-ppa/mainline/v4.5.4-yakkety/linux-headers-4.5.4-040504-generic_4.5.4-040504.201605120823_amd64.deb
$ wget kernel.ubuntu.com/~kernel-ppa/mainline/v4.5.4-yakkety/linux-image-4.5.4-040504-generic_4.5.4-040504.201605120823_amd64.deb
$ sudo dpkg -i linux-headers-4.5.4*.deb linux-image-4.5.4*.deb

Be careful with using newer kernels (4.6..) because it seems that NVIDIA drivers dont compile yet: https://www.reddit.com/r/linuxmint/comments/4jqvip/psa_nvidia_drivers_will_not_compile_against/

At least when I tried 4.6, it didnt work in my notebook. Maybe it is a good idea to check again and this will surely change soon.
