We installed Mathematica 10.3 in a Linux Computer (ubuntu 12.04.5 LTS). It worked well several weeks and now it doesn't start anymore. The error messages that we get are:
libGL error: failed to load driver: nouveau
libGL error: Try again with LIBGL_DEBUG=verbose for more details.
LinkConnect::linkc: -- Message text not found -- (LinkObject[ngdrk_shm, 3, 1])
Can someone give me some clues?
