[g45] [gm45] [Karmic] Xorg doesn't display full area on external monitor

[jc00ke]

Binary package hint: xserver-xorg-video-intel

I plugged in my Dell 24" S2409W with HDMI into my Lenovo IdeaPad Y650 (418534U) and turned on the dual monitor using the Display applet. Correct resolution found: 1920x1080 but the full screen could not be used. It's as if the screens are overlapping, but they are not set to do that in the applet.

2 screenshots are attached. One is a photo of my computer when the screensaver was on. You can see the area that is essentially inactive. I expected the displays to show the full screens for each monitor.

I have a similar issue, but in my case, the combination shown above works (see attachment 'screenshot-small.png', purple area is visible area).

However, because of bug #389519 (pointer gets lost above the upper menubar), I want to move my small primary screen up to align it with the top of the bigger screen.
  But when I do this, I get a big rectangular black part on my primary screen (see attachment 'screenshot-1-small.png, again, purple area is the visible area).

I know that this very bug reports a "mirrored background" on the secondary screen, and I get a black rectangle on my primary screen, but I thought that these issues are quite related.
  Should I create a new bug for this?

Tried again today, and this time it works. Haven't done any updates since.

This bug report has been inactive for quite some time and in the meantime Ubuntu has moved along. I hope the reported problem has been resolved in the current version of Ubuntu. If it has not and there are people willing to follow up with information collecting and testing, it is best to file a new bug report with the latest Ubuntu development version (currently 10.04, but soon 10.10), using the ubuntu-bug command if possible. Feel free to mention the bug number of this bug.

We are sorry that we are not always have the capacity to look at all reported bugs in a timely manner. Occationally we have to purge old bug reports where no progress has been made, whether it is due to reporter not being able to respond or lack of manpower on the Ubuntu side, in order to keep our list of "active" bugs current. Sorry for the inconvenience this may cause.

Here are a few tips that will increase the chances that your bug gets priority:
* Read https://wiki.ubuntu.com/X/Reporting
* Browse https://wiki.ubuntu.com/X and see if there is some relevant information for you problem
* Respond quickly to questions from triagers
* Try changing things to see if the behaviour changes, e.g.
  * A new mainline kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=M;O=D (more information at https://wiki.ubuntu.com/KernelTeam/MainlineBuilds)
  * The xorg-edgers PPA: https://launchpad.net/~xorg-edgers/+archive/ppa
  * Various options in `/etc/X11/xorg.conf` (see `man intel`)
* Browse other bug reports to see if you find a similar one and provide the information that is being asked for there.

If the bug creeps out in Lucid, I'll post a new report.
