Description Tom 2015-07-02 07:53:25 UTC 
I have the impression that is wrong since the Kubuntu 15.04 upgrade, but I'm not sure about that. Target system: Windows Server 2012R2. 

when i start xfreerdp directly (cmd below) its working correct.

xfreerdp -decorations /w:1920 /h:1200 /kbd:0x00000807 /u:<username> /parent-window:106954797 /bpp:24 /audio-mode:0 /drive:media /media /network:lan /rfx /cert-ignore +clipboard /port:3389 /v:<servername>

Qt: 4.8.6
KDE Development Platform: 4.14.6
KRDC: 4.14.6

Linux <hostname> 3.19.0-21-generic #21-Ubuntu SMP Sun Jun 14 18:31:11 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux


Reproducible: Always

Steps to Reproduce:
1. Connect to Win Server via RDP with Numlock on
2. Test Numblock keys -> not working
3. Set Numlock off -> Numblock keys working.


Expected Results:  
correctly working Numlock key
Comment 1 Tom 2016-03-09 14:22:11 UTC 
it's not always inverse. sometimes its working normal. I guess there should be some sort of check if the Numlock Key is active or not after connection and set it to the right state.
Comment 2 Vaso 2016-10-25 09:00:44 UTC 
I think it should be a simple option like /numlock-on in xfreerdp. But this is an upstream FR.

This annoying bug and suddenly "sticky" Control key make our users mad. We have to use remmina. (Remmina, in KDE, really?)
Comment 7 Petr Kovács 2020-04-07 19:27:39 UTC 
I can confirm this bug - after connecting to a remote Windows server with KRDC, the numlock status is often inversed to actual numlock status of my linux desktop.

Operating System: Gentoo Linux
KRDC Version: 19.12.3 
KDE Plasma Version: 5.18.4
KDE Frameworks Version: 5.68.0
Qt Version: 5.14.1
Comment 8 RM 2025-05-18 07:09:21 UTC 
Reporting numlock state still inverted with wayland + krdc 25.04 + Plasma 6.3.5.
