problem of Bumblebee

Hello,

I have installed Bumblebee packages in my laptop from

http://download.opensuse.org/repositories/X11:/Bumblebee/openSUSE_Tumbleweed/

with command line

*zypper in bbswitch bumblebee dkms nvidia-bumblebee nvidia-bumblebee-32bit primus VirtualGL-devel  VirtualGL-32bit *

I have blacked list “blacklist nouveau” to /etc/modprobe.d/50-blacklist.conf as well.

However, when I try to run the following command line:

> systemctl status bumblebeed
        ● bumblebeed.service - Bumblebee C Daemon
           Loaded: loaded (/usr/lib/systemd/system/bumblebeed.service;        enabled; vendor >
           Active: active (running) since Wed 2019-01-16 23:24:40 CET;        6min ago
         Main PID: 1846 (bumblebeed)
            Tasks: 1 (limit: 4915)
           Memory: 584.0K
           CGroup: /system.slice/bumblebeed.service
                   └─1846 /usr/sbin/bumblebeed


      >optirun glxgears

it always failed with messages:

*   36.405200] [ERROR]Cannot access secondary GPU -            error: Could not enable discrete graphics card**   36.405224] [ERROR]Aborting because fallback            start is disabled.*

I Goolged it, and found the following

It seems that this is mainly because the dkms-nvidia and        nvidia-bumblebee were mismatch. Does anybody have any suggestions?

Thanks a lot.

It’s not clear that the error message on your system will necessarily be as a result of the same problem as on Arch.
You’ll need to do more than the steps you listed to get bumblebee support for your card.
You should follow the instructions which are applicable to Tumbleweed here if you haven’t already.

Once that’s done you’re probably still going to have issues if you’ve updated to kernel 4.20 because the upgrade will likely have broken *nvidia-bumblebee *in the repo you’re using.

To fix that you could use the repo listed here for the proprietary Nvidia driver version 390
