Hello,

this is the same machine and symptoms that
<a class="bz_bug_link 
          bz_status_RESOLVED  bz_closed"
   title="RESOLVED FIXED - [915 TV(integrated)] querying Randr-information enables LVDS output due to spurious transient TV detection"
   href="show_bug.cgi?id=31519">https://bugs.freedesktop.org/show_bug.cgi?id=31519</a> were reported for. I decided
to report a new bug because it's a different kernel/xorg combination now
compared to the two years old previous bug.

Chipset: 915GM
System arch: i686
Distribution: Debian (Jessie)
Machine: Thinkpad X41
related packages:
  libdrm-intel1: 2.4.58-2
  xserver-xorg: 1:7.7+7
  xserver-xorg-core: 2:1.16.1.901-1
  xserver-xorg-video-intel: 2:2.21.15-2+b2
  linux-image-3.16.0-4-686-pae: 3.16.7-2

When I run

    xrandr --output LVDS1 --off

the LVDS output goes off as expected, but then running

    xrandr

without option reenables it again.</pre>
