Title:
  Screen blanks and freezes after a few minutes of idling, possibly due
  to broken DPMS

Status in xf86-video-siliconmotion:
  Confirmed
Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  Since switching to Gutsy to verify whether the packages I maintain
  still operate as expected, I have noticed that after a  few minutes of
  idle operation, the screen goes blank and cannot be returned to
  normal. The only way to get screen content again is to reboot, which
  is possible either by pressing the ACPI-enabled power button or a
  remote SSH connection. Broken DPMS is suspected, although I have no
  way of confirming this.

  Purposely downgrading xserver-xorg-core and anything that depend on
  it, then pining it to that version, while keeping all the rest of the
  packages to Gutsy versions solves it, which suggests something related
  to X.org upgrade from 1.2 to 1.3 might be at play.

  Note: someone on #ltsp mentions a similar situation using xserver-
  xorg-video-amd, yet the exact same AMD driver doesn't exhibit this
  behavior when compiled and used with earlier X releases.
