[Bug 669125] Re: Part of screen is truncated on external HDMI monitor

 

** Description changed:

  Binary package hint: xorg
  
  I have installed Ubuntu 10.10 on an external HDD without major problems.
  However, I have an external monitor connected via HDMI to my Acer
  Timeline 1810T notebook (Intel graphics). On this external monitor the
  screen resolution is correctly set to 1920x1080. However, parts of the
  screen are truncated. If I make a window go to full screen, not all
  parts are visible.
  
  Changing the resolution does not change this behavior. Also, setting the
  external screen as the only video source does not change the problem
  (currently it is set to extend the notebook monitor). I have googled a
  bit and found that at least two people experience the same problem:
  
  http://www.linuxquestions.org/questions/ubuntu-63/ubuntu-10-10-and-hdmi-
  screen-resolution-838728/
  
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/550486
  
  Since the latter bug report does not seem to fit my problem completely,
  I decided to file a new one.
  
  My xorg package is:
  xorg:
    Installiert: 1:7.5+6ubuntu3
    Kandidat:    1:7.5+6ubuntu3
    Versionstabelle:
   *** 1:7.5+6ubuntu3 0
          500 http://us.archive.ubuntu.com/ubuntu/ maverick/main amd64 Packages
          100 /var/lib/dpkg/status
  
  Hope this helps to fix the problem, I also encountered it on another
  notebook with a different monitor (also HDMI with Intel graphics).
  Apparently this is an HDMI or Intel graphics card issue.
