Great! So it looks like Bumblebee is not compatible with the SUID wrapper in xserver-xorg-legacy. I will try to investigate as soon as I have time.

The upstream primus developer mentions this in a bug report about the same message you get [1]. From what I can understand, both Primus and VirtualGL (the 2 bridges supported by bumblebee) only supports GL calls, but GLX is needed by Firefox to enable WebGL. So it looks like it's not supported by upstream, sorry. Anyway, my personal recommendation would be to just use the integrated card for browsing/video playback. These days the Intel GPUs are more than well equipped to handle that kind of workload. Optimus/Bumblebee come in handy for games and Cuda/OpenCL :-) Kind regards, Luca Boccassi [1] https://github.com/amonakov/primus/issues/43#issuecomment-13932246
