Citrix Workspace App update
The Citrix Workspace App version is updated to 2101.
● ICA session cursor pattern—The ICA session cursor pattern setting is added in the Admin Policy tool or Wyse Management
Suite policy settings to configure the cursor behavior during a Citrix session. Sign off from the Broker agent or reboot the
client to make this setting take effect. The setting can force areas of the cursor to be black or white. The following values
can be used:
○ ffff,ffff—Enter this value to set the cursor color as black. This value is set by default.
○ 0,0—Enter this value to set the cursor color as white.
○ aaaa,5555—Enter this value to set the cursor color in a dotted pattern.
● Citrix logging—Supports export of Citrix logs for troubleshooting purposes. For more information about how to export Citrix
Workspace App logs in ThinOS, see the Dell Wyse ThinOS 9.1 Administrator's Guide at www.dell.com/support.
Limitations:
● Zoom optimization using the proxy server is not supported.
● Microsoft Teams optimization using the proxy server is not supported.
● RTME using the proxy server is not supported.
● Pause/Break and Scroll Lock does not function in Citrix session when the Keyboard Layout Mode is set as Server Default.
You must change the Keyboard Layout Mode to non Server Default and reboot the client to make Pause/Break and Scroll
Lock work.
● The maximum supported compatible version of Webex Meetings app on the hosted virtual desktop is 41.3 for
WebexMeetings v40.10.11.15.6 pkg. To use Webex meetings optimization in ThinOS, IT administrators must not upgrade
Webex meeting server site higher than 41.3. Ensure that you have referred the Compatibility between the Webex
Meetings Desktop App and the Thin Client Plugin table to configure Webex Meetings optimization mode environment.
To access the compatibility table, do the following:
1. Go to help.webex.com.
2. In the search bar, enter Cisco Webex Meetings Virtual Desktop Software, and press Enter.
3. Click Cisco WebEx Meetings Virtual Desktop Software from the results.
4. Scroll down the page to view the Compatibility between the Webex Meetings Desktop App and the Thin Client
Plugin table.
● If a user logs in to the Citrix broker using the web-based login, the Last User and Last Logged-in User entries are not
displayed on Wyse Management Suite. Also, the user credentials that are pushed to the client using Wyse Management Suite
cannot be used for logging into the Citrix broker that uses the web-based login. You can use the web-based login when
configuring the Citrix ADC using Azure AD SAML with SSO and Citrix ADC Native OTP features.
Microsoft Direct Remote Desktop Protocol updates
● Supports Auto-Connect on Start-Up—You can configure the Auto-Connect on Start-Up option from ThinOS local UI,
Admin Policy Tool, or the Wyse Management Suite policy settings. Enabling this option allows the thin client to automatically
connect to a Remote Desktop Protocol connection on system startup. For more information about how to configure the
Auto-Connect on Start-Up , see the Dell Wyse ThinOS Version 9.1 Administrator's Guide at www.dell.com/support.
NOTE:
The Save local connections option should be enabled before experiencing this feature. Go to Wyse
Management Suite or Admin Policy Tool > Session Settings > Global Session Settings to enable the option.
● Supports Remote Desktop Gateway—You can log on to the Remote Desktop Gateway using the ThinOS Local UI. For more
information about how to configure the Remote Desktop Gateway, see the Dell Wyse ThinOS Version 9.1 Administrator's
Guide at www.dell.com/support.
