xorg-server (2:1.18.3-2) unstable; urgency=medium

  X now defaults to using built-in modesetting video driver on Intel
  hardware which is "4th gen GMA" and newer, so roughly speaking on hardware
  from 2007 and up. If this triggers new bugs on your hw, please file them
  against the xserver.

  Continuing to use the -intel driver is possible by dropping the template
  xorg.conf to /etc/X11:

  # cp /usr/share/doc/xserver-xorg-video-intel/xorg.conf /etc/X11

xorg-server (2:1.17.3-1) unstable; urgency=medium

  The Xorg server is no longer setuid root by default.  This change reduces the
  risk of privilege escalation due to X server bugs, but has some side effects:

  * it relies on logind and libpam-systemd
  * it relies on a kernel video driver (so the userspace component doesn't
    touch the hardware directly)
  * it needs X to run on the virtual console (VT) it was started from
  * it changes the location for storing the Xorg log from /var/log/ to
    ~/.local/share/xorg/

  On systems where those are not available, the new xserver-xorg-legacy package
  is needed to allow X to run with elevated privileges.  See the
  Xwrapper.config(5) manual page for configuration details.
