Doc Text:	Previously, when attempting to connect multiple displays using a Windows 7 guest, remote-viewer would only show one display available, even when all settings in the manager and on the SPICE client itself were correctly configured. This was caused by a regression issue relating to changes to custom resolution commands. Now, connecting and displaying multiple monitors functions correctly.	Story Points:	---

This menu is dynamic only when the guest has dynamic multi-monitor config.

Is the guest 2nd monitor enabled?

Hi Marc-Andre,

Yes I checked in DeviceManger and both monitors are enabled, and the 2nd display is not shown by remote-viewer.  

I disabled one of the monitors from DeviceManager and restarted the system, and then remote-viewer shows me two displays, one of which is black and unusable.  If I then enable and start the RHEV Spice Agent (which gets shutdown after system restart after disabling one of the monitors) the 2nd display it works properly; however, after closing out remote-viewer (both monitors enabled) and launching it again from the UP/PUP it only shows one display.

And the 2nd one won't show up until I again disable one of the monitors and restart the VM and start the same process over again.

Comment 2 Marc-Andre Lureau 2013-03-18 18:00:51 UTC

This is probably a regression since we introduced the "escape" command for custom resoltion. The CreateGC call fails on disabled monitor, causing the rest of monitor configuration / auto-enable to fail.

Verifed that mingw-virt-viewer-0.5.3-23.el6ev, now has the 2nd monitor enabled form the View Display options when doing multimonitor, 

*tested it with Windows 7 client x86_64 and Windows 7 x86_64 guest
