Release Notes

Dell Wyse ThinOS 8.5_009 | 40
Troubleshooting
 ThinOS devices allow secure SSL connections—SecurityMode=Full—only after verifying
the certificates. In the current scenario, the devices enforce the warning policy after you
define a server using a valid IP address. The resolution for the issue will be delivered in the
next ThinOS release.
The following are the workarounds to avoid the SSL connection issue:
o Ensure that the device has a valid certificate and the correct time is selected on the
device.
o Define the server by name instead of IP address.
o Set the value of the global security policy to high.
o Use the following INI parameter to enforce the high security mode:
SecurityPolicy=high TLSCheckCN=Yes
 The base.i386 and pcoip.i386 packages may not be available on devices:
o Shipped with ThinOS version 8.5
o Reimaged with a ThinOS version 8.5 Merlin image using USB imaging tool

NOTE: Devices with 2 GB flash are not affected by the package issue.
Problem statement: The following issues are observed on the affected platforms:
o Multimedia performance issues occur because the required codecs are not available.
o PCoIP connections are not started in Horizon View and AWS environments.
o Package tab is not available in the System Tools menu.
Resolution: Perform one of the following steps to resolve the issue on the affected devices:
o Use the 4 GB Merlin image to flash the devices with 4 GB flash configuration. Use the
8 GB Merlin image to flash the devices with 8 GB flash and higher configurations.
o Install the ThinOS 8.5 web image to reload the missing package files. You can install
the ThinOS web image by using either a file server, Wyse Device Manager (WDM), or
Wyse Management Suite. If the ThinOS web image is stored on a file server or
management server, and if the automatic image update option is enabled using the
INI parameter Autoload=1 LoadPkg=1 is enabled, then the device automatically
installs the base.i386 or pcoip.i386 packages during system reboot.
 Firmware/Package update: When the packages fail to update or cannot function (cannot
connect desktop) after update with new version firmware; if there is further failure, a work
around would be to remove all packages and re-install all of them on reboot.
 Display: With DP audio by default enabled, the Wyse 3040 thin client in certain resolution will
display 10 seconds’ black screen after boot up (for example. 1920 x 1200, 2048 x 1152, 2048
x 1280, 2560 x 1080, 2560 x 1440).
 Blast connection: if there any is launch problem check the remote desktop status as well as
network status; reboot unit few times and the desktop connects successfully.
