Bumblebee can't access secondary gpu [Dell XPS 15 9570]

I have a GTX 1050 Ti and I've followed these instructions from Arch Wiki on how to use this GPU with Bumblebee, but even though I've followed them thoroughly I get this error when I get to the part when I have to check if the GPU is working:

[sajmon@sajmon-laptop ~]$ optirun glxgears
[ 1101.982723] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver

[ 1101.982858] [ERROR]Aborting because fallback start is disabled.

After checking the logs I've found out that modprobe doesn't work

Am I doing something wrong?

Re: Bumblebee can't access secondary gpu [Dell XPS 15 9570]

Your kernel is outdated, if you've recently updated you will want to reboot.If you think you did reboot post

pacman -Q nvidia
pacman -Q linux

Re: Bumblebee can't access secondary gpu [Dell XPS 15 9570]

Updating didn't really help me, as this problem has persisted through multiple updates. Nevertheless, here's the output of the commands:

[sajmon@sajmon-laptop ~]$ pacman -Q nvidia
nvidia 430.26-9
[sajmon@sajmon-laptop ~]$ pacman -Q linux
linux 5.2.arch2-1
[sajmon@sajmon-laptop ~]$
