ThinOS enhancements
The following updates are added to the ThinOS local settings:
● DisplayPort audio is set as the default audio when you hot plug a monitor that supports DisplayPort audio.
● Usage of special characters is restricted in Terminal Name. All types of characters are allowed except " ", "+", "=", "/", "\",
":"
● Supports keyboard layout switching using hotkeys, layout list, and tray icon from the ThinOS desktop. For more information
about how to switch between keyboard layouts, see the Dell Wyse ThinOS 9.1 Administrator's Guide at www.dell.com/
support.
● Supports uploading Host File from Admin Policy tool or Wyse Management Suite and synchronize the file to the client to
resolve FQDN in the host file. It supports ANSI or UTF-8 encoding, and the maximum file size is 10 KB. You can configure the
host file settings from Advanced tab > System Settings > Device Settings > Host File Settings on Admin Policy Tool or
Wyse Management Suite policy settings.
● Supports selecting the starting Serial Port number and remapping the Serial Port number. For more information about
how to start serial port number and remap the serial port number, see the Dell Wyse ThinOS 9.1 Administrator's Guide at
www.dell.com/support.
● When a private certificate with CA information is imported, the client displays CA information and private certificate
information in System Tools > Certificates.
● Proxy is enabled for configured applications only, irrespective of availability of DHCP 252. If you configure empty value
on Local UI, the Local UI helps to enable for all supported applications by default. If you configure empty value on Wyse
Management Suite or Admin Policy Tool, proxy is enabled for none according to the Proxy Application List configuration. If
DHCP 252 is available, the Wyse Management Suite is enabled to go through proxy by default even when Wyse Management
Suite is not configured in Proxy Application List configuration.
● Simple Certificate Enrollment Protocol (SCEP) auto renew—When auto renewal happens on the client, the client needs
password to renew the client certificate. If you are using an enrollment password which can expire in some time, the
enrollment password should be valid when auto renew behavior happens on the client. Dell Technologies recommends you to
use admin credentials, or fixed enrollment password to auto enroll certificate, and auto renew certificate.
Troubleshooting updates:
● Added Clear log and Capture debug logs options to the troubleshooting window on the ThinOS UI. For more information
about how to use Clear log and Capture debug logs options, see the Dell Wyse ThinOS 9.1 Administrator's Guide at
www.dell.com/support.
● Added FPS option in Troubleshooting > General > Performance Monitor > CPU on the ThinOS UI. While playing videos
on Citrix session using client renders such as Multimedia Redirections, and HTML5 video, FPS is displayed on Performance
Monitor.
NOTE: Horizon Blast does not support this function in this release.
Admin Policy Tool and Wyse Management Suite policy settings
updates
The following options are added to the Admin policy tool and Wyse Management Suite policy settings:
● NetScaler and ADC login timeout—Added the option Netscaler and ADC Login Timeout for Citrix Virtual Apps and
Desktops Settings of Admin Policy Tool and Wyse Management Suite to configure server timeout when logging in to Citrix
NetScaler. By default, timeout works when logging in to Citrix NetScaler. Disabling the setting causes the NetScaler login to
have no timeout.
NOTE: Disabling the setting is a security risk as anyone using the terminal can launch the desktop at any time.
● Login use smartcard certificate only—Added the option Login use smartcard certificate only in Admin Policy Tool and
Wyse Management Suite policy settings. This option enables you to use smartcard certificates during broker login. Other
certificates such as user certificates are ignored. For more information about how to log in using a smart card certificate, see
the Dell Wyse ThinOS 9.1 Administrator's Guide at www.dell.com/support.
● Lock terminal—Added the Lock terminal option in Admin Policy Tool and Wyse Management Suite policy settings. The
Lock terminal option is enabled by default and helps to lock the thin client. For more information about how to lock the
terminal, see the Dell Wyse ThinOS 9.1 Administrator's Guide at www.dell.com/support.
NOTE: The command of lock terminal from Wyse Management Suite ignores this option, always take effect.
● Enable HID Fingerprint reader—Added the HID Fingerprint reader option in Admin Policy Tool and Wyse Management
Suite policy settings under Global Session Settings. This option is disabled by default and must be enabled to be used.
