[gm45] Part of screen is truncated on external HDMI monitor

[Henning]

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.

Hey Henning,

Thanks for your interest in Ubuntu.

Thanks for testing maverick during its development period. Unfortunately it looks like this bug report didn't get attention during the maverick development period. But I see there's not been more comments on the bug since the release, which makes me wonder if this is still an issue for you?

If you've not seen this issue since maverick's release yourself, it may have been solved by kernel or X or other updates that occurred late in the release; if so, would you mind please closing the bug for us? Go to the URL mentioned in this bug report, click the yellow icon(s) in the status column and set to 'Fix Released'.

If you no longer have the hardware needed to reproduce the problem, or otherwise feel the bug no longer needs tracked in Launchpad, you can set the status to 'Invalid'.

If you are the original reporter and still have this issue, just reply to this email saying so. (Or set the bug status to Confirmed.) If you are able to re-test this against 11.04 Natty Narwhal (our current development focus) and find the issue still affects Natty, please also run 'apport-collect <bug-number>' while running natty, which will add fresh logs and debug data, and flag it for the Ubuntu-X development team to look at.

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
