    Default How can I test/troubleshoot Nvidia drivers?

    Hi, I have a Dell XPS with a graphics card Nvidia GeForce GTX 1050. I had some issues with the nouveau drivers, so I installed the proprietary Nvidia drivers following the "easy" approach here ( https://en.opensuse.org/SDB:NVIDIA_drivers#Using_zypper ). The problems have gone, so I'd say that it worked.

    Still, I would like to know for sure that this is working, and I have no idea how to double check it. For instance, in my old days I remember using glxinfo, glxgears and so on. What are the equivalent nowadays? Do you know of some simple application/game that I can use to benchmark the 3D acceleration somehow?

    Something that puzzles me, and perhaps some guru can explain, is why I still see the intel drivers in lspci (I have removed non-relevant stuff):

    Code:
    # lspci
    00:02.0 VGA compatible controller: Intel Corporation Device 591b (rev 04)
    01:00.0 3D controller: NVIDIA Corporation Device 1c8d (rev a1)
    Is this how it should be? What is the intel driver doing there? And a related question, how can I find out which kernel modules am I using related to graphics? I do not see anything related to nvidia in lsmod

    I am aware my question are rather general and unspecific, but although I have the basis to understand all this, I find that there are some basic details that are missing in the documentation I could find online.

    Thank you very much!

    Same now but you have to install Mesa-demo-x

    Most if not all consumer Intel CPU also have a GPU built in.

    Is this a notebook? if so you may need bumblebee

    If not turn off the Intel GPU in the BIOS/UEFI

    first check that the module is load well into the kernel:
    Code:
    lspci -v | egrep  "3D|VGA" -A20
    for test :
    Code:
    DRI_PRIME=1 glxinfo | grep "OpenGL vendor string"
    on my laptop, with nvidia driver answer are "OpenGL vendor string: Intel Open Source Technology Center" but if i test
    Code:
    DRI_PRIME=1 glxspheres
    the performance tells me that I'm on the Nvidia card
