Administrator Guide

In the server default mode, both Linux and Windows use the session (VDA) side keyboard layout with predictable output. In this
release, ThinOS has a customized Citrix package where the keyboard layout is set to server default mode for predictable output.
The keyboard layout that you select on the thin client is not automatically synchronized in the VDA session. VDA users must
select or switch the keyboard layout inside the VDA session using the Windows Input Method Editor (IME) language bar.
As a VDA administrator, you must configure the VDA desktop with the required keyboard language layout options. The IME
language bar must be enabled on the Windows lock screen. The VDA user can select the appropriate keyboard language layout
on the Windows lock screen.
In scenarios such as opening a new application in a VDA session, locking, or unlocking the VDA session, the keyboard layout falls
back to the VDA default layout. For example, EN_US. This is a known issue for a Linux client in the server default mode.
You can customize VDA registry settings for a consistent keyboard layout in the VDA session.
● For a desktop operating system VDA, the feature is enabled by default.
● For a server operating system VDA, you can enable the feature using the system registry.
1. In the system registry of VDA, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard
Layout.
2. Create a DWORD entry IgnoreRemoteKeyboardLayout=1.
By default, the IgnoreRemoteKeyboardLayout entry is unavailable. The default keyboard is set to ENG, irrespective
of the Control Panel setting.
For example, open an application, lock, or unlock the session, the keyboard is set to ENG. To resolve this issue, ensure
that you set IgnoreRemoteKeyboardLayout=1.
For information about the Keyboard Layout Modes and Keyboard Layout rules in Citrix Workspace app, see the Citrix Virtual
Apps and Desktops keyboard and IME configurations article at www.citrix.com/blogs.
