The problem is that you don't have libglcore.so as part of proprietary
drivers (nvidia, for e.g.). At this time libglcore is substituted with
mesa-dri/glx (which is abs. soft-ware rasterizer, not using your video
card 3D acceleration) and xserver-xorg-video-nouveau (queer subst. for
native video card drivers).

Try to run glxgears, glxinfo and you'll see error - glxinfo: error
while loading shared libraries: libGLcore.so.1: cannot open shared
object file: No such file or directory
