Dear Christopher,

thank you for your reply. I have updated the BIOS with what appeared to
be the newest version available from Dell.

I now get
> sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
A10
08/28/2013

I did not experience any freeze for a short while (one full day, while
my laptop was plugged into power). Today, while my laptop was running on
battery power I experienced the first freeze since the BIOS upgrade.

It appears identical to what I used to have before upgrade (i.e. not
only the laptop does not respond, to keyboard/trackpad, but the screen
displays some strange pattern, cfr. the image attached to my first bug
report).

Title:
  Xorg freeze on DELL XPS13 L322X Ubuntu 15.10

Status in xorg package in Ubuntu:
  New

Bug description:
  Since the upgrade to Ubuntu 15.10 I am experiencing frequent freezes.
  This did happen on the same system before the upgrade, but not nearly
  as frequently. It seems to happen randomly. As of now I have no other
  computer that I can use to access my own during freezes by ssh and
  confirm that this is a graphic only issue / gather further info.

  Before upgrading I had other issues on this laptop (laptop shutting
  down randomly after resuming from suspend) which are seemingly
  resolved by the upgrade.

  The way that the screen freezes is most peculiar. I attach a picture
  of the screen for information.
