[virt-tools-list] Initial number of displays when remote-viewer is launched via RHEV 3.3

[Mike Savage]

​Hello,

If you have multiple monitors defined when you launch a console session in RHEV, remote-viewer starts with only one display connected.  You have to then check the extra displays in the drop down menu for the additional displays to appear. What I'm looking to implement is a way to define how many displays are desired upon that _initial_ session launch.  If you toggle the number of desired displays, disconnect from the session and then reconnect via REHV, the desired number of displays reappear correctly.  However, it's that _initial_ console connection (whether from the admin portal or user portal) that only connects the number 1 display.

My thin client build is currently based on a local F19 spin I put together, Firefox in kiosk mode, with local RHEV Admin Portal as initial web page. I have put together a wrapper script that takes into account the number of physical monitors connected/configured via the X server, the overall desktop resolution, then moving each correct remote-viewer display window to each respective monitor, finally fullscreening all of them...via wmctrl.  I just need that initial connection to launch the specific number of displays desired, without having to toggle the extra displays in the drop down menu.

Looking in the src for virt-viewer, a lot of information is passed from RHEV that remote-viewer picks up...session, host, port, tlsport, user, etc. Could an additional parameter be added that it looks for?  Perhaps via a special hook parameter, allowing the desired number of initial displays to be opened upon initial launch?  In addition, the setting probably needs to be directly related to individual user logins or to specific pools (and/or both via fallback?).

Guidance in how this should be implemented would be great. It really makes the entire solution look well-polished, if the end users (who are typically windows users) do not have to perform extra steps to get their VDI windows desktops utilizing all of their monitors.   In the current POC i'm working on for a customer, the vast majority of the VDI users have three monitors. Some have two, or in some cases one if they are on their laptop, but 9x% have three monitors.  The major sticking point at the moment is the end users having to click on extra display toggles at initial desktop connection and arranging them on the correct monitors.

Any assistance that could be provided is greatly appreciated.

Thanks,

Mike
