Period key on numerical keypad

The issue occurs with the following keyboard layout and Windows language on Windows remote session and with the conditions bellow:

  • Brazilian Portuguese ABNT and ABNT2 keyboard layout
  • Brazilian Portuguese language and Brazilian Portuguese ABNT and ABNT2 keyboard layout on Windows session
  • The issue occurs after updating from ThinOS 8 to ThinOS 9 versions but is not limited to upgrades, occurs on ThinOS 9.
  • The issue occurs on wired and wireless Brazilian Portuguese ABNT and ABNT2 keyboards regardless of the make and model.

Cause

The issue is a combination of problems with WVD package and ThinOS 9.x, both have been fixed in ThinOS 2402 and later.

How to reproduce:

  1. Press any key.
  2. ThinOS computer sends key-code to the AVD package.
  3. AVD package transforms a key-code into a scan-code and sends the scan-code to the windows session.
    • The key-code is encoded under Linux.
    • The scan-key code is encoded under Windows.
    • Some keys are coded differently, and AVD has to be able to map to them.
Note: The period key is one of the keys that did not get mapped. The fix is to add a mapping for these keys.

Resolution

The fix is available on ThinOS 2402 and later, download by going to Drivers & Downloads for your model Thin Client.
