I'm also having some problems with the newest kernel version below are some relevant errors from my dmesg, just trying to help provide additional information in case this is related. My display-manager instantly crashes whenever I plugin in a displaylink device. I think I'll call it SaaS (Segfault as a Service).

$ uname -r

@FancyFane There is currently an issue with the new libmesa 13.x package. Downgrade to 12.x should fix this, see https://bbs.archlinux.org/viewtopic.php?pid=1666503#p1666503

Otherwise, check this two things, which helped me once:

  1. Delete /var/lib/gdm/.*
  2. Check custom configs in /etc/X11/xorg.conf.d/ which breaks the displaylink devices with xrandr.
