Also occurs booting into 4.13.0-21-generic
Please install the oibaf ppa and see if latest mesa fixes the issue.
I installed these but after an apt-get upgrade yesterday the system does not boot to the login screen and I do not have any network anymore... Also, before the fatal upgrade the colors seemed not to be right, and some drop-down menus did not work in Firefox.
