from nxagent-3.0.0-88 changelog:
- Fixed TR10D01539. Some XKEYBOARD requests are disabled if the option
'keyboard' has value 'query'. This locks the initial keyboard map.
Enabling/disabling of XKEYBOARD requests is done at run time.
- Added -noxkblock command line option enabling the XKEYBOARD requests
even if the option 'keyboard' value is 'query'.
