I’m trying to get an NVIDIA 970M GPU working after something went wrong with the drivers. I’ve tried purging and manually wiping the system of everything nvidia/cuda related and reinstalled both from the
ppa:graphics-drivers/ppa and from the NVIDIA installer.
Both approaches fail to get the system to use the NVIDIA GPU (as evidenced by nvidia-prime which I use to switch to the NVIDIA GPU, but after reboot it always returns to the onboard intel GPU).
- What I’m trying to understand now is exactly what configuration in
ubuntu is used to configure which graphics drivers are actually
- How do I actually query the kernel to understand what drivers it
thinks are available, and which drivers it is using?
Are there logs other than dmesg (with show nothing special) that I
should be looking at to debug this?
