dmesg dump after suspend/resume

My Lenovo X1 extreme with Nvidia GeForce GTX 1050 Ti Mobile graphic card works
fine with nouveau driver. But if system is suspended to RAM or goes in
hibernation, graphic card fails leaving screen blank. But I still able to login
into machine with ssh.

With OEM Nvidia driver everything work fine, but this is not an option for my,
as a have a USB docking station with DisplayLink not supporting OEM driver.

--- Comment #1 from James Jones <jajones at nvidia.com> ---
Just a note: The binary NVIDIA driver (I assume that's what the OEM driver
is)
does support DisplayLink outputs if configured correctly.  It's effectively
the
same as an optimus configuration.  See these sections in our documentation for
more information if you're interested:
