Description of problem: RHEL guest cannot extend its desktop to 2nd monitor after connect to it with remote-viewer for several times. Version-Release number of selected component (if applicable): virt-viewer-0.5.2-16.el6.x86_64 spice-server-0.12.0-2.el6.x86_64 spice-glib-0.14-5.el6.x86_64 spice-gtk-tools-0.14-5.el6.x86_64 spice-gtk-python-0.14-5.el6.x86_64 spice-vdagent-0.8.1-3.el6.x86_64 spice-gtk-0.14-5.el6.x86_64 spice-protocol-0.12.2-1.el6.noarch How reproducible: Sometimes, about 95% Reproduce steps: 1. Have a notebook computer and plugged another display to its VGA interface. 2. Install a rhel guest on it, make sure it has spice+qxl device and spicevmc channel. 3. Update spice-vdagent and xorg-x11-drv-qxl 4. Run remote-viewer spice://127.0.0.1:5900 --full-screen=auto-conf 5. Close remote-viewer. 6. Repeat step 4 and 5 for several times. Actual results: 1. After step 6, 2nd monitor becomes to a mirrored one. Expected results: 1. 2nd monitor should be an extended monitor. Additional info:

I can reproduce this: 1. Get dual screen physical setup. 2. Connect to a guest with remote-viewer. 3. Go to fullscreen (even with one guest screen VM). 4. change resolution within the guest -> suddenly two mirrored screen shows up. Note sure this is a bug of virt-viewer, mostl likely spice-vdagent.
