[ 309.431928] [ERROR]Cannot access secondary GPU - error: [XORG] (EE)

[ghost]

01:00.0 VGA compatible controller: NVIDIA Corporation Device 1f91 (rev a1)

I've entered the BusID as stated above in /etc/bumblebee/xorg.conf.nvidia.

ii  bumblebee-nvidia                              3.2.1-20
ii  nvidia-driver                                 430.50-1

When running something with optirun I get
Cannot access secondary GPU - error: [XORG] (EE)
When using triple verbose mode

[ 3145.384236] [DEBUG]Using auto-detected bridge primus
[ 3145.506617] [INFO]Response: No - error: [XORG] (EE) 

[ 3145.506637] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) 

I believe this might be related to #915 but I have no way to know for sure as I cannot reproduce the output of the gpu-manager command.

I currently also have this issue I'm running Ubuntu 20 Focal.

I got another issue on Ubuntu 20: #1054

Maybe they are somehow related. On Ubuntu 18 everything was ok.

you need to install the latest linux kernel and nvidia driver from official website, which is newest version 440.82 with dkms module installed, and uninstall all packages related to nvidia, then install bumblebee, and it would work like a charm!

sudo apt install linux-headers-5.6.10-oem linux-image-5.6.0-1010-oem linux-modules-5.6.0-1010-oem
sudo reboot
sudo init 3
cd Downloads/
sudo sh $(ls | grep NVIDIA)
sudo reboot
sudo apt install bumblebee primus
sudo reboot
optirun glxgears
