Dell Wyse ThinOS Version 8.6 and ThinOS Lite 2.6 Operating System Release Notes

VMware Client updates

• Updated the VMware Horizon package version from 4.8 to 5.0.

  If you are upgrading your thin client to ThinOS version 8.6_024, ensure that the Horizon server or agent version is updated to 7.5 or later to support the latest Horizon Client version 5.0.

• Supports the relative mouse feature in a PCoIP session.

  When you enable the relative mouse feature, Horizon Client uses absolute coordinates to transmit data about the mouse pointer movements and improves the mouse performance. To enable the relative mouse feature on a classic desktop, right-click the remote desktop icon on the ThinOS taskbar, and click Enable Relative Mouse. To enable the relative mouse feature on a zero desktop, go to the ThinOS connection menu, and click the A icon that is displayed after the PCoIP session name.

  The relative mouse feature is applicable only for the following PCoIP-enabled thin clients:

  • Wyse 3030 LT thin client
  • Wyse 3040 thin client
  • Wyse 5010 thin client
  • Wyse 5040 AIO thin client
  • Wyse 5060 thin client
  • Wyse 5070 thin client
• Supports the High Color Accuracy feature in a Blast session with H.264 enabled. H.264 is disabled by default from this release. You can enable H.264 using GUI or INI parameters.

  The High Color Accuracy option enables Horizon Client to use a superior color fidelity when H.264 decoding is enabled. To enable the High Color Accuracy feature, go to Global Connection Settings, click the Horizon tab, and select the High Color Accuracy check box.

  The High Color Accuracy option is available on the following platforms:

  • Wyse 3030 LT thin client
  • Wyse 3040 thin client
  • Wyse 5060 thin client
  • Wyse 5070 thin client
  You can also use the INI parameter SessionConfig=BLAST RemoteDisplay.allowClientH264YUV444=TRUE/FALSE to enable the High Color Accuracy feature.
• Supports the Username Hint option during smart card authentication for the Horizon View broker.

  You can enable users to specify the account to be used in the Username Hint field when you log in to a Horizon View session using a smart card. To enable the Username Hint option, go to the View Administrator Admin console, and select the Allow smart card user hints check box when editing the View Server Connection settings. Enabling this option allows you to use a single smart card certificate to authenticate to multiple user accounts.

• Enhanced the reconnect workflow for VMware Horizon View broker using the INI parameter VMWaitTimer={0–3600}.

  The option VMWaitTimer specifies the time remaining in seconds for reconnecting to a Horizon desktop before exiting the desktop. When the connection fails while connecting to a Horizon desktop, a message Horizon Error- Waiting to recover is displayed along with the countdown timer.
