View 5.x PCOIP Black screen on reconnecting

[simonalexander]

G'Day,

Hoping people can throw suggestions and ideas forward on this one.

Our View deployment is accessible internally and over the net through a security server (PCOIP Gateway) setup.

We have an ongoing problem where users get the PCOIP black screen when reconnecting to their desktops.

2x scenarios where this can happen (not every time, maybe 1 out of 5 times):

User is working on LAN and then disconnects, Goes home and connects over the Internet. Session establishes but user gets a black screen.

User is working over Internet and then disconnects, Comes into the office and connects on LAN. Session establishes but user gets a black screen.

If we reset their virtual desktop, everything works again. If they log off the virtual desktop instead of disconnecting, everything works fine.

I am assuming the problem is because the protocol/port is "owned" by the disconnected session. Although the PCOIP logs appear to show valid disconnection and "connection closed" entries.

I have checked KB: 2003767 and we don't have a policy enforcing the lock thingo

Any help appreciated.

Cheers,

Simon

Hi there, not sure if you figured this out yet as it's been awhile but we had pretty much the same exact thing happening in our environment. The cause in ours was two different things..

The first thing I noticed the sessions would not reconnect when the user had a screensaver enabled and was running. I sent out a windows GPO to disallow CPU intensive screensavers and force only the blank screen saver, this fixed some of the issue for some users but was still happening frequently for others. The solution that seemed to ultimately work for everyone was to simply uninstall vmware view agent, reboot (yes really), uninstall vmware tools, reboot (yes still really), re-install tools making sure to UNCHECK the SVGA driver, reboot, install view agent and reboot again. Since doing that, everything been smooth again. I have a feeling that somewhere along the line vmware tools was upgraded w/o reinstalling view agent afterwards and that screwed up the SVGA driver.
