[GTALUG] Laptop (very) weirdness

[William Park]

- What kernel version?  Slackware recently downgraded from 4.14.2 to
  4.9.67.

- As Hugh mentioned, try logging in as another user.  Though, if it's
  KDE handling of network, then there should be no difference.

- Instead of logging into KDE desktop, log into console (Alt-Ctrl-Fn).
