There is an issue which may occur when you install or upgrade your VMware Tools after having installed your View Agent. The set of VGA drivers shipped with VMware Tools might sometimes be incompatible with VMware View and PCoIP, whereas the VMware View Agent software contains a supported VGA driver.
For this reason, today we’re highlighting the KB article we have written up for this issue: Error attaching to SVGADevTap, error 4000: EscapeFailed reported by PCoIP server (1029706)
To resolve this issue, you must update the drivers to the version supplied with VMware View Agent. The KB also includes a nice table of video drivers supplied with different VMware View Agent versions and operating systems.
