I'm running Ubuntu 16.04 with an MSI GTX 970, and I have two monitors. I read up on how to make it work, and learned that I'd have to use the proprietary drivers, so I changed the drivers, and the system settings wouldn't open. I tried going to the terminal and running unity-control-center, and was met with:
(unity-control-center:21126): GLib-CRITICAL **: g_strsplit: assertion >'string != NULL' failed Segmentation fault (core dumped)
How can I fix this? I had it working just fine before, but I had to reinstall for unrelated issues.
