R SIG Fedora - Jan 2016 - rgl.snapshot only captures a small portion what's visible in the RGL device window on CentOS 7

Tom,

Bingo!

I followed the instructions in the link below, which allowed me to install the
nvidia driver, which fixed the original problem with rgl.snapshot.

Thanks very much for all your help.

I guess I'll file a bug in the CentOS Bug Tracker so that the nouveau driver
might get fixed. I'll also post to R-help so someone with the same problem
who only searches R-help and not this SIG will see the solution.

-Ben

I have not tried it personally, but these instructions seem correct:

Basically, edit the grub2 cmdline to include the extra option:

  rdblacklist=nouveau

Awesome. If you have the cycles, I'm sure the CentOS people would
appreciate it if you ran through the nouveau troubleshooting first:

http://nouveau.freedesktop.org/wiki/Bugs/

You might consider also filing a bug with the Nouveau upstream, as the
CentOS people may not be experts with that driver, but the upstream
certainly will be. Keep in mind that they may want you to test the
latest version of the driver first.

Glad we got it working for you though. :)

Tom,

I thought about filing a bug report with Nouveau, but it seems that working
directly with Nouveau is well beyond my capabilities.

I have no idea how to do most of the stuff Nouveau says to do in their
troubleshooting page. And for the small minority of things that I think I might
be able to figure out, each one would take me hours of reading and
experimentation and begging for help. I'm not an OS guy.

And also, I don't think I can afford to be frequently installing and
uninstalling drivers because I need my machine to be stable for my real work.

Nouveau's bug reporting page says "If you are using packages from your
distribution and are unable/unwilling to test the latest versions of all the
pieces of nouveau, send the bug reports to your distribution and not directly to
us." So I thought I should submit the bug report to CentOS.

I'm hoping that it will be relatively easy for someone at CentOS to
reproduce the bug and then take it from there, probably working with Nouveau.

-Ben

Ugh.

Below I declared victory, but today I learned that the NVIDIA driver has a
problem the nouveau driver did not have. Namely, when using the NVIDIA driver,
if I plot a lot of stuff in the RGL window and then using the mouse expand the
RGL window, R usually crashes.

One work-around seems to be to
1) close all RGL windows, if there are any
2) call rgl.clear() to create an RGL window
3) re-size that window using your mouse
4) do your plotting
