VMware View, Wyse Zero Client and the Windows Lock Screen

I'm wondering if anyone else has experienced this odd situation:  We are running View 5.2.0 agent with Windows 7 x64 on a 5.3 server and use Wyse P24/45 zero clients for the users desk.  Each desk has (so far) two monitors.  Everything is fine, however in some situations when a user locks their workstation to walk away, it will lock but still display a static image on the secondary monitor of whatever was open there at the time of lock.  So for instance, if a user had cnn.com open on the right (secondary) monitor when they lock, that page is still visible, while on the left (primary) monitor the standard

CTRL-ALT-DEL screen is shown.  The page (or whatever is still visible) is in no way interactive, and since the image is static, even if the page auto-refreshes you will only ever see the content as it appeared when the machine was locked.  When the user unlocks, both screens go black as they normally do and then display current content.

Has anyone else seen anything like this?  It's not the biggest of deals, however it would be a security concern if a user left a sensitive document up on their secondary monitor, and locked their workstation to walk away.

Wow, that sounds weird.

How are you outputting to two monitors? Possibly the cable that is used?

You should definitely raise this with support - the screen should be actively blanked as it would on a physical workstation, but it sounds like that's not happening for some reason (at a guess, if the lock screen is disabling the second monitor, perhaps the zero client doesn't understand that and leaves the last-known image). Is this also reproducible with the latest zero client firmware and/or the 6.0 agent?

It's definitely strange.  The Zero is connected via a straight DVI cable, and on the second port a DP to DVI adapter then a DVI cable.  I hadn't though of the cables possibly being an issue, I'll swap those out as an easy elimination task.  Thanks!

I wasn't thinking about the cables (though feel free to try), I was thinking more that the PCoIP remoting hasn't correctly told the client that the second monitor was disabled.

I was thinking of opening a ticket, however the random and non-replicable on demand nature put me off for now.  Hard to even describe accurately, since it doesn't happen every time and I can't nail down what circumstance will cause it.  It does happen with both the latest (4.5.0) and a previous (4.1.2) firmware from Teradici, however I have not even attempted the 6.0 agent yet.  So far only on P25 zeros, although those are the most common I have deployed right now.

Actually have been working with support on an issue with the 5.3.1 agent, that does not appear in the 5.2.0, so I'm not completely taking out the possibility of this being something in the image itself.

I agree, cables are extremely unlikely, however it will be good to eliminate them as any possibility.  I'm also going to enable some enhanced logging on the zero, hopefully to catch something next time it happens.  I'm guessing this is not all that common Smiley Happy

I had the same exact issue. I updated the VMtools , which in turn updated the Video Driver. and it seems to have fixed the issue. Hope this works for you.

Yep, exactly how I resolved display issues within our instance. GenericITWorker
Install the Horizon Agent, restart, update VMTools, restart. Recompose or push out the image and test it again.
