I am reading an installation procedure and it indicates "remove nouveau drivers" (as indicated in the docs)
My question is why is it necessary to do this? What are the benefits or effect?
Also when I do this
lsmod | grep nouveau
Nothing appears. Is it still necessary to remove the drivers?
According to the documentation linked to in the question To install the Display Driver, the Nouveau drivers must first be disabled. This disables the Nouveau driver, but it does not uninstall it.
When installing a proprietary graphics driver, it is not necessary to uninstall the built-in Nouveau open source graphics driver. The two graphics drivers can be installed alongside each other allowing the open source graphics driver to be used as a fallback alternative in case there is a problem using the proprietary graphics driver after installing or updating it. If you can enter into
recovery mode from the grub boot menu you can enable the Nouveau driver from there by changing options nouveau modeset=0 to options nouveau modeset=1 in /etc/modprobe.d/blacklist-nouveau.conf.
