Got the same error this morning.
Note that it happens after an apt-get dist-upgrade with an update of mesa +
reboot
Same error this morning when I plugged an external monitor:
GL_VENDOR = Intel Open Source Technology Center
GL_RENDERER = Mesa DRI Intel(R) Ivybridge Mobile x86/MMX/SSE2
GL_VERSION = OpenGL ES 3.0 Mesa 9.2.1

Cannot start any Mir server ... std::exception::what: Failed to set

Bug description:
I can't seem to start any mir server any more. It always fails with:
sudo bin/mir_demo_server

Running it locally, or as root does not help. And there's no other Mir server
running. Only plain X:
/usr/bin/X :0 -core -auth /var/run/lightdm/root/:0 -nolisten tcp vt8
-novtswitch
