Description Geyang Kong 2012-11-14 07:35:25 UTC 
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-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.

Comment 3 Marian Krcmarik 2012-12-04 19:52:23 UTC 
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.
