Comment 87 for bug 1072206

I seems that upgrading to v16.04 (and then reinstalling drivers) has fixed
this issue for me. Time will tell.

$ dpkg --get-selections | grep -v deinstall | grep nvidia
nvidia-352 install
nvidia-361 install
nvidia-opencl-icd-361 install
nvidia-prime install
nvidia-settings install

$ uname -a
Linux haunted-linux 4.4.0-22-generic #39-Ubuntu SMP Thu May 5 16:52:40 UTC
2016 i686 i686 i686 GNU/Linux
