[Scilab-users] Ubuntu upgrade just killed GL

[Clément David]

Hello Tim,

Thanks for the report, FYI I checked a Scilab 6 local build and a Scilab 5.5.2 on Ubuntu 16.04 and
it seems to works (at least plot3d works).

I suggest you to reboot and trying to report your issue to Ubuntu on glxgear (which is the right 3D
testing tool).
