Citrix Alt Gr Keyboard Problem

Original post is here eklausmeier.goip.de/blog/2026/04-24-citrix-alt-gr-keyboard-problem.

1. Problem statement: You access a Windows machine, while running on Linux. You can no longer type characters like ~, |, [, ] These are characters where you needed to press the key Alt Gr on a German keyboard.

2. Solution. The following configuration added to ~/.ICAClient/wfclient.ini solves the issue:

KeyboardType = 0
KeyboardEventMode = Scancode
KeyboardSyncMode = No

In Windows I set "Keyboard synchronization setting" to "Don't sync".

3. Derivation of solution. This time it was Grok which after three questions just replied with the solution given above.
