Description Tom "spot" Callaway 2011-04-12 14:45:51 UTC 
Description of problem:

On my desk, I have a Lenovo Thinkpad T500 in a docking station. Attached to the docking station is an Acer Technologies 22" LCD monitor. This monitor is mounted on a stand so that it is vertically above the Thinkpad LCD panel.

Fedora 15, running GNOME Shell, detects the Acer Technologies 22" monitor correctly, and the "Displays" tool shows it positioned vertically above the Thinkpad LCD panel. The two displays are aligned on the right edge.

The Acer LCD is at 1680x1050 (16:10). The Thinkpad LCD is at 1920x1200 (16:10).

The Thinkpad T500 has dual graphics chipsets (Intel and ATI Radeon), but only the ATI Radeon is enabled in BIOS at the moment.

The "Displays" tool shows that both monitors are enabled, and indeed, the background appears on both screeens, and the mouse can easily move from top to bottom. 

The bottom screen (the Thinkpad LCD) has the GNOME Shell bar at the top, and new windows open in the bottom screen. However, no new windows will open in the top screen, nor can windows be dragged to the top screen. When this is attempted, the "drag" icon (and just the drag icon, not any part of any application window) appears on the top screen, but when the mouse button is released, the window instead snaps to fill the entire bottom screen. 

Version-Release number of selected component (if applicable):

gnome-shell-3.0.0.2-1.fc15.x86_64
xorg-x11-drv-ati-6.14.0-7.20110316gitcdfc007ec.fc15.x86_64
kernel-2.6.38.2-9.fc15.x86_64

How reproducible:
Every time

Steps to Reproduce:
1. Boot into GNOME Shell
2. Try to use "top" monitor
Comment 1 Owen Taylor 2011-04-12 16:54:17 UTC 
Tracked upstream. Even if the dragging was fixed, there would be additional issues making it hard to use vertically stacked monitors. It's suggested for now to configure them as side-by-side.

Where?  A link to the upstream bug(s) would be useful.

Owen set the "External Bug ID" to GNOME Desktop 636963, when he closed this bug out. You can see it in the "External Trackers" section above.
