#91 Able to blackscreen X server with Chromium

[Lloyd Wood]

glxinfo reports Chromium 1.3, so I'm reporting this bug here.

Environment is 64-bit Ubuntu 16.04 LTS running on VirtualBox 5.1.22 on a Windows 7 host. Vanilla, up to date, etc. Up to date guest additions in VirtualBox.

savi and geomview are Ubuntu packages. (I maintain them, they're both on sourceforge.)

sudo apt-get install geomview
sudo apt-get install savi

geomview -run savi

You'll see a bunch of windows open, one with a simple view of the Earth. In the light blue SaVi - satellite constellation window, select the Rendering menu, and select the 'Show coverage cones' menu option from that menu.

This reliably blanks the entire Ubuntu screen in the Virtualbox window to black. As I mouse around the cursor type will change, indicating that it's aware of the different windows. I just can't see anything. In twenty years of using SaVi and Geomview, I've not experienced anything like this. Commanding Geomview draw a single OpenGL cone in its camera window should not do this to the X display.

(you can restart the virtual machine, and rerun geomview -run savi and select Earth viewing options to see Chromium OpenGL in action. Just don't select coverage cones...)

Adding glxinfo

Chromium is no longer updated or maintained. The project is frozen. It hasn't had an update in over 10 years.

[Lloyd Wood]

If Chromium hasn't had an update in ten years, why is Ubuntu using it? thanks.

[Sean Ahern]

I couldn't tell you. And that version is ancient even for Chromium. I think
version 1.9 was the latest. I don't have any idea why you're getting the
code you're getting. It could be someone's confusion between our Chromium
project (cluster rendering) and Google's newer and unrelated Chromium
project (code underlying the Chrome web browser).
