Title:
  turning off attached TV disables it

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Binary package hint: xserver-xorg-video-ati

  The sole monitor attached to this computer is Toshiba 42XV54SU
  television.  When I turn the television off, and later turn it back
  on, the computer display does not appear (other inputs, such as cable
  TV do work).

  The only way I have found to restore the display without restarting X is this script:
  #!/bin/sh
  DISPLAY=:0.0 xrandr --output DVI-1 --off
  DISPLAY=:0.0 xrandr --output DVI-1 --auto

  (I run it from another computer using SSH, since I can't see what I'm
  doing.)

  I have disabled the screen saver and the Power Managment setting "Put
  display to sleep when inactive for" is set to Never

  I used this setup under Jaunty and Karmic for the lives of those
  distros, and did not experience this issue.  It seems to be new in
  Lucid.  (OTOH, 3D acceleration works in Lucid for the first time, and
  I have Desktop Effects enabled.)
