Can you reproduce this with "Classic Desktop" and "Classic Desktop (no effects)"? From your description it sounds similar to what I see when trying to use unity on multi-head systems, so I'm wondering if it's that.
If it does reproduce with Classic Desktop and no compiz, and you still suspect -intel, then try seeing if downgrading to an earlier -intel makes it go away. .debs can be gotten from Launchpad here: https://launchpad.net/ubuntu/+source/xserver-xorg-video- ati/+publishinghistory just click the version you want to test, and then click the architecture under build (amd64 in your case) and snag the .deb file. If you can narrow in on exactly what version the regression started at, that'd be a huge help. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/727382 Title: Unable to correctly display Image on 24" External Monitor -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
