X Keyboard Extension (XKB) configuration

Starting with the 2407 release, the Linux VDA specifies evdev as the default XKB rule for keyboard configuration. This decision can be justified for several reasons:

Most modern Linux distributions use the evdev XKB rule by default.
Almost all applications are following the key code pattern of the evdev XKB rule.
The evdev XKB rule provides extended support for a wide range of key symbols beyond basic alphanumeric characters and typical function keys, such as ‘Cancel’, ‘Redo’, ‘Undo’, ‘XF86Copy’, ‘XF86Open’, and ‘XF86Paste’.
The evdev XKB rule in Linux addresses various keyboard-related issues, particularly those concerning incorrect responses to key inputs.

If you want to switch back to the XFree86 rule, you can make the following registry setting:

/opt/Citrix/VDA/bin/ctxreg update -k "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Citrix\LanguageBar" -v "XkbRuleName" -d "xorg"
<!--NeedCopy-->

In this command, only the exact case-sensitive text ‘xorg’ is recognized as the ‘xfree86’ ruleset; any other input values are ineffective.
