andrea lattanzi commented on GUACAMOLE-859:
-------------------------------------------
Our Server was on 1.1 and the CAPS LOCK was behaving well.
The bug 1008, high RDP memory allocation has made our work impossible. So we
tested guacd 1.2 but we found this bug.
The remote RDP machine is W7 , the keyboard layout is set by guacamole as US.
The bug has been verified from Windows and Ubuntu clients with IT keyboard
layout.
> Incorrect Caps Lock keysym sent to Windows via RDP
> --------------------------------------------------
>
> Key: GUACAMOLE-859
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-859
> Project: Guacamole
> Issue Type: Bug
> Affects Versions: 1.0.0
> Environment: macOS Mojave
> Windows 10
> Reporter: Weston Thayer
> Priority: Minor
> Fix For: 1.2.0
>
>
> 1. On a Mac, connect to a Windows machine via an RDP connection in Guacamole
> 2. On the Windows machine, open Chrome or Firefox and navigate to
> https://jsbin.com/reviciceke/2/edit?js,console,output
> 3. Click the "Run with JS" button
> 4. Click the output pane to make sure it has keyboard focus
> 5. Press the Caps Lock key on your Mac (you may need to press it twice if
> it's already on)
> Actual: The JSBin's console outputs KeyboardEvent.code and KeyboardEvent.key
> for the "keypress" event. Note how KeyboardEvent.code is an empty string and
> KeyboardEvent.key is "Unidentified"
> Expected: KeyboardEvent.code should be "CapsLock", as should KeyboardEvent.key
> I believe the keysym being sent by guacamole-common-js's Keyboard.js is
> 0xffe5. I'm guessing the guacd RDP plugin has a bug, where that keysym is not
> mapped to the correct RDP scancode(?).
> For reference, using Microsoft's RDP client for macOS, KeyboardEvent.code and
> key are correctly "CapsLock".
> Note that this bug probably went un-noticed for a long time because Caps Lock
> still "works" in that future characters typed are capitalized. But in my use
> case, I need Windows to handle the Caps Lock key down itself.
