No HDMI output in Ubuntu 22.04 LTS with GeForce RTX 2070 Mobile

Hi everyone,

Followed a tutorial to install drivers for my RTX2070 in Ubuntu 22.04LTS (I can’t link it as I’m restricted to one link and I need to link the bug report°)

I ended up installing the nvidia-driver-515 even though it is not the recommended one.

ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd00001F14sv00001462sd000012BCbc03sc00i00
vendor   : NVIDIA Corporation
model    : TU106M [GeForce RTX 2070 Mobile / Max-Q Refresh]
driver   : nvidia-driver-470-server - distro non-free
driver   : nvidia-driver-510-server - distro non-free
driver   : nvidia-driver-515-open - distro non-free recommended
driver   : nvidia-driver-450-server - distro non-free
driver   : nvidia-driver-515 - distro non-free
driver   : nvidia-driver-510 - distro non-free
driver   : nvidia-driver-515-server - distro non-free
driver   : nvidia-driver-470 - distro non-free
driver   : xserver-xorg-video-nouveau - distro free builtin

Now, I don’t have any HDMI output for my second monitor. Nvidia-smi fails :

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

The additional driver GUI shows nvidia-driver-515 is installed and selected.

Linking the bug-report file here :

Any help or lead appreciated.
