Hi
I have Dell Precision 5760 with NV Quadro RTX A3000(6G) card, and it comes with preinstalled Ubuntu 18.04,
when I tried to connect to my external Monitor, but it doesn’t work.
and it has nvidia-driver-470 driver installed, here are some video card check result:

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

sudo journalctl -b0 _COMM=gdm-x-session --no-pager > journal.txt

Also my have hard driver full encryption is enabled, but I can’t disable it, is this the reason that Driver could not be loaded?

[ 1.831309] [drm] Your graphics device 9a60 is not properly supported by the driver in this
kernel version. To force driver probe anyway, use i915.force_probe=9a60
module parameter or CONFIG_DRM_I915_FORCE_PROBE=9a60 configuration option,
or (recommended) check for kernel updates.

You’d need a newer kernel to support your integrated GPU.
Sounds just stupid from Dell to install Ubuntu 18.04 on it.
I’d recommend installing Ubuntu 20.04 and a HWE kernl with it.

The nvidia driver is loading.
But also is the nouveau, which should be blacklisted.
The nvidiafb driver also needs to be blacklisted (maybe that’s the reason the X server quits saying it can’t run in framebuffer mode).

However as said before, I’d install a newer OS and kernel.

Ok, Thank you for your response, Iet me try the configuration change first. we are still using 18,04 for development, 20.04 will cause other problems. if it doesn’t work, I will try upgrade OS.
