My games crash and webGL doesn't work with Manjaro KDE

Hello,

I’m running Manjaro KDE and I was previously running the Intel integrated graphics driver.

I went on the IRC channel #manjaro to find some help and someone told me to delete the integrated Intel graphics driver and then to run

sudo mhwd -f -a pci nonfree 0300

It still doesn’t work. I ran the nvidia-bug-report.sh script but it seems it didn’t work well :

modprobe: ERROR: could not insert 'nvidia': No such device

Anyway, I drop you the nvidia-bug-report.log.gz file here : https://www.dropbox.com/s/l842i4qwhj2f6mf/nvidia-bug-report.log.gz?dl=0.

Thank you for your help.
