Bug Description
In "Software & Updates" the recommended NVIDIA binary driver - version 331.38 (proprietary, tested) is selected. Furthermore the dialog displays "1 proprietary driver in use" (see screenshot).
Nevertheless, running `lshw -c video` shows that (after several reboots) nouveau is still used:
*-display
description: VGA compatible controller
product: GT218M [NVS 3100M]
vendor: NVIDIA Corporation
physical id: 0
bus info: pci@0000:01:00.0
version: a2
width: 64 bits
clock: 33MHz
resources: irq:42 memory:
As another symptom running "nvidia-settings" does not display any devices.
Everything worked fine when enabeling the proprietary driver the first time. I then reverted back to nouveau and then tried to enable the NVIDIA driver again. Since then the problems started. Purging and re-installing the NVIDIA packages did not help.
I have the exact same problem :
