How to install CUDA on 18.10 for an Optimus laptop?

I have a Thinkpad W520 with NVIDIA Quadro 1000M + integrated Intel GPU. I have just made a fresh install of Ubuntu 18.10 on it.



I want to achieve the following:




  • working CUDA,

  • working external display through DisplayPort/VGA,

  • in Optimus mode, if possible (selected that in the BIOS).


Status before installing anything



I had nouveau set up by default. It finds the external monitor through both DisplayPort and VGA (the connectors on the laptop), but it does not work consistently: the external monitor gets switched off after some time.



What I've done



I tried to install CUDA along with the corresponding NVIDIA driver:



sudo apt install nvidia-cuda-toolkit
sudo ubuntu-drivers autoinstall


Had a mysterious crash in the middle of compiling the kernel modules, then finished the install after a reboot with dkpg --configure -a. In the end, it installed CUDA 9.1.



At this point, the laptop:




  • boots in Optimus mode,

  • it does not detect external VGA monitor (will need to test HDMI),


  • glxinfo says that direct rendering is Yes,

  • the graphics is however not smooth (I see triangle-like artifacts appearing on screen when I move a window, or part of the screen is refreshed),

  • after unpacking and compiling some samples from the original 9.1 toolkit installer to verify CUDA, it turned out that CUDA also has problems.


matrixMul does not work, see output:



Error! Matrix[204798]=0.00000000, ref=3.19999981 error term is > 1.000000E-06
Error! Matrix[204799]=0.00000000, ref=3.19999981 error term is > 1.000000E-06
Result = FAIL


Strange enough, deviceQuery does work, see output:

On an older Ubuntu version booting in NVIDIA-only mode selected in BIOS solved most of these problems (even though the battery drained very fast because of the lack of Optimus). However, this time Ubuntu does not boot at all in this mode.

From what I've seen nvidia do not support ubuntu 18.10 as their driver does not work with the new abi 24. You are probably not running with the nvidia driver.



try adding the following two repositories to your sources.list



deb http://us.archive.ubuntu.com/ubuntu/ bionic main
deb http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64 /


and downgrade xserver-xorg-core and xserver-xorg-video-* and install cuda (which should install cuda-10)



see if that helps.



Cuda is generally backward compatible, so while the 1000m was relatively capable at the time, it's very old by now (8 years if memory serves) and I'm not sure how many things are still supported on it, but it should still run. As for battery, unless you replaced it recently, it's probably beyond end of life, so I wouldn't look at the battery as an indicator.
