Sudo vs LD_PRELOAD errors

[Shak]

I use vglrun +wm to launch my desktop environment, i3, to allow all apps that are used to enjoy VGL acceleration. This work well and I am satisfied with the results.

However each time I execute a sudo command in the envoronment I get the following errors:

ERROR: ld.so: object 'libdlfaker.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

ERROR: ld.so: object 'libvglfaker.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

The actual command runs fine. I suspect that this is a) innocuous and b) by design as per the docs at https://virtualgl.org/vgldoc/2_2/#hd0012

However it is also quite irritating! Are there any known workarounds (aside from the setguid one from the above link) to hide this message? Perhaps a clever sudo alias that might hide this output?

No. I've been the principal developer and sole maintainer of VirtualGL
from the beginning (2004), and I have never seen any way around that
except making the faker libraries setuid root.

I should footnote that to say that, if you don’t actually need to use VirtualGL as root, then you could alias sudo to ‘unset LD_PRELOAD; sudo’ or something similar. Having LD_PRELOAD set when running something as root (or something that is setuid root) is what gives you that error message.

I don't actually need to run GL apps under root so that's a great, and for me correct, solution!
