So I dont think nvidia is actually being used ?
apt list --installed |  grep -i nvidia

nvidia-340/focal-updates,now 340.108-0ubuntu5.20.04.1 amd64 [installed]
nvidia-opencl-icd-340/focal-updates,now 340.108-0ubuntu5.20.04.1 amd64

nvidia-settings/focal-updates,now 460.39-0ubuntu0.20.04.1 amd64
[installed,automatic]

lspci | grep VGA
03:00.0 VGA compatible controller: NVIDIA Corporation GT218 [ION] (rev a2)

nvidia-detector
nvidia-340

cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-5.4.0-72-generic
root=UUID=76aeeff4-4d65-4f4a-889e-5f12ae03068b ro splash nouveau.modeset=0
nomodeset acpi=off vt.handoff=7

What might I not have right ?
Thanks.
