External Email - Use Caution Hi Alex, I see via a search for, ubuntu 16 Failed to initialize XRandr - that what you report happens when trying to connect remotely, e.g., via VNC, to something running X windows/graphics (for other flavors of linux as well). This thread,https://serverfault.com/questions/788503/xrandr-error-when-accessing-debian-vm-over-vnc- seems to indicate the version of libGL.so could be an issue. One take away is if you are trying do run X remotely, then you can test to see if a simple X program like glxgears can be run remotely (before trying to run freeview). I don’t think this one is much help as it reads like you already have these installed,https://askubuntu.com/questions/1039129/randr-extension-missing There could be interactions going on w.r.t what you have installed, and then having to set/configure some things so X can work remotely thru the google cloud. I don’t know how/if Goggle cloud supports X forwarding etc., but I do know that other ways of doing cloud virtualization, e.g., thru docker containers, needs some work to run X applications remotely. Maybe google cloud taking your virtual machine image and turning it into some kind of “container” to run (which can be done with docker I believe). If possible, I would first test the Ubuntu 16 virtual machine by running it directly on a local machine and check that glxgears and freeview work.. Then I would try running it in the cloud and see what happens with respect to trying to run those programs remotely. If you don’t have to use Ubuntu 16, we have an Ubuntu 18 virtual disk image you can download and run that already has everything installed to run 7.1.0 (and you could update it to 7.1.1), https://drive.google.com/file/d/1bPvF9m2z4yRDIOv51B5bihU1VN_o2J5x/view?usp=sharing - R.

I followed those instructions, it seemed that all those libraries were already installed. Freeview still won’t launch (even after rebooting).
