[Bug 314930] Re: [i915] switch user causes screen to alternate solid colors in intrepid

[Bryce Harrington]

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  When I try to switch users, a new VT appears to start initializing.  But
  after a few mode switches, about 75% of the time the screen then starts
  to flash all solid colors, changing about once per second:
  
  red, blue, green, white, black,
  red, blue, green, white, black,
  
  and so on, ad infinitum.  In order to use my display again, I have to
  kill all open X displays with Ctrl-Alt-Backspace.  At that point gdm
  starts again, and I can log in.
  
  The result is that I'm generally limited now to having only one user
  logged in at a time.  Sometimes a 2nd user can log in successfully, but
  when I try to switch back, I always get the solid colors and have to
  kill all of the sessions again.
  
  Attaching Xorg.0.log, and output of lspci -vvnn.  Note that I can't be
  sure which VT is flashing the colors, so I'm also attaching Xorg.20.log.
  
  Thanks,
  Andrew.
