Support for multiple language inputs

Feb 26, 2018

As of the Linux VDA Version 1.4, Citrix has added support for published applications. Users can access a desired Linux application without the Linux desktop environment. 

However, the native language bar on the Linux VDA was unavailable to the published application because the language bar is highly integrated with the Linux desktop environment. As a result, users were unable to input text in a language that requires IME such as Chinese, Japanese, or Korean. Further, it was also not possible for users to switch between keyboard layouts during an application session.

To address those issues, this feature provides a language bar for published applications that accept text input. The language bar enables users to select a server-side IME and to switch between keyboard layouts during an application session.

Configuration

You can use the ctxreg utility to enable or disable this feature (disabled by default). The feature configuration on a given Linux VDA server applies to all applications published on that VDA.

The configuration key is “HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Control\Citrix\LanguageBar” and the type is DWORD. 

To enable this feature, run the command:

Command Copy 
/opt/Citrix/VDA/bin/ctxreg update -k "HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Control\Citrix\LanguageBar" -v "Enabled" -d "0x00000001"

To disable this feature, run the command:

Command Copy 
/opt/Citrix/VDA/bin/ctxreg update -k "HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Control\Citrix\LanguageBar" -v "Enabled" -d "0x00000000"

Usage

The usage is straightforward.

  1. Enable the feature.
  2. Access a published application that can accept text input. A language bar appears in the session, alongside the application.
  3. From the drop-down menu, select Region & Language to add the desired language (input source).

4. Select the IME or keyboard layout from the drop-down menu.
5. Type a language using the selected IME or keyboard layout.

Note

  • When you change a keyboard layout on the VDA-side language bar, ensure that the same keyboard layout is used on the client side (running Citrix Receiver).
  • The accountsservice package must be upgraded to Version 0.6.37 or later before you can perform settings in the Region & Language dialog box.
