[Bug 959343] Re: Incorrect screen resolution


This version is no more supported and is not a 'security' problem; so
does not expect a backport

  Incorrect screen resolution

Status in gnome-control-center package in Ubuntu:

Bug description:
  I'm using an Elysion U1 computer together with a BenQ projector.
  Ubuntu reports that the monitor is not detected and defaults to a
  screen resolution of 1280x800 pixels.

  When I use the monitor preferences to change the resolution to
  1024x768 (which is the correct resolution for this projector), the
  image gets even more blurry than when the incorrect resolution is

  xdpyinfo claims the resolution has been changed to 1024x768 pixels,
  but the actual output being sent on the DVI port is still 1280x800

  It appears Ubuntu has configured the graphics chip to scale the
  1024x768 image to 1280x800 pixels which the projector then needs to
  scale back to 1024x768 pixels, which results in a blurry output, which
  is almost unreadable.

  The bug exists in both the preinstalled Ubuntu 9.04 as well as in the
  Ubuntu 10.04, that I just installed from the official Ubuntu DVD
