For a long time, I have used the NVIDIA proprietary driver. In Additional Drivers the NVIDIA driver was activated. However, I just "Removed" that driver because I would like to use the Nouveau driver for other reasons. Yet, I have reason to believe I am still using the NVIDIA driver as the output of
modprobe -l is as follows:
$ modprobe -l | grep 'nvidia' kernel/drivers/video/nvidia/nvidiafb.ko
How do I really determine what driver I am using, and how to I enable Nouveau?
