Bug#1031804: nvtop: Crashes on multi-gpu system while using PRIME with chromium/chrome

[Jesse Rhodes]

I took a second look this morning now that the meeting is over, and
I've determined that it only crashes if chromium or google-chrome is
being run with the PRIME environment variables.

nvidia-smi output as well as temp sensor data indicated that the
nvidia gpu was being used for chrome as I had hoped, but something
about this prevents nvtop from working.

chrome prints the following to the console after being launched with
the aforementioned env vars:

MESA-LOADER: failed to retrieve device information

But otherwise works as expected.
