Failed to start GPU process

[dhill2522]

This nasty-looking error has come up when running m.GUI() to launch the gui on some machines.

As far as I can tell this is not actually an issue with the Gekko project itself, but is actually an error being thrown from chromium in this case. It is also a problem for our friends on the jupyter project as is evidenced in their issue 2836

@loganbeal would you mind trying some of the suggestions from our friends in the above jupyter issue and seeing if that resolves your problem? I have not been able to reproduce it here.

export BROWSER="chromium-browser" before launching spyder does resolve this issue. Is this a reasonable long-term solution? Should we just add a note in the docs to set the appropriate BROWSER environment variable if you're experiencing this issue?

Interestingly, export BROWSER="google-chrome" launches chrome instead of chromium, but chrome can't connect to the server (localhost refused to connect) and the kernel restarts automatically.
Also interestingly, I get the same gpu error when launching chromium or chrome from the CLI:

> chromium-browser 
> Created new window in existing browser session.

Maybe we do want to just put a note in the docs until the problem seems to go away or we learn more about it. Either way I do not think it is an issue with our code, so I am closing this out.
