Here's an update on this... If, when in GRUB, I select the Advanced option and then choose the (upstart) option, it works OK.
If I do the default boot, it nearly always results in the error message and no wifi. I hope this will give you some idea of what is going wrong. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1783850 Title: Cannot find display configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1783850/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
