dwm[vnc[dwm]] Mod1 button

[ichensky]

Describe the bug
It is not possible to use Mod1 button inside of VNC session.

To Reproduce

1. Start vncserver inside of DWM https://dwm.suckless.org/

$ vncserver

2. Connect to it:

xtigervncviewer -SecutiryTypes VncAuth -passwd /home/john/.vnc/passwd :1

3. Inside of VNC windows try to switch between DWM windows with Mod1+1..Mod+5...Mod+9 keys.

4. Instead of switching to another window inside VNC[dwm] , windows would be switched at the host DWM.

**Client **

• OS: debian buster
• VNC client: TigerVNC
• VNC client version: 1.9.0
• Client downloaded from: my Linux distribution

**Server **

• OS: debian buster
• VNC server: TigerVNC
• VNC server version: 1.9.0
• Server downloaded from: my Linux distribution

Ehm... what is a Mod1 button? Or are you referring to the modifier list? Which button are you pressing?

Your description sounds like your local window manager is grabbing this key. You need to be in fullscreen with the system keys setting enable for TigerVNC to intercept things the local window manager normally uses. Have you tried that?

Mod1 it is Alt button. Tried to start xtigervncviewer with -FullScreen, it works, thank you.
Tested with xinput application:
when xtigervncviewer started in normal mode it do not fully handle key combinations(it only handles pressing of the first button), for ex. when pressed Alt+2, xinput inside of vnc window log only Alt. Checked the same behavior with virt-manager, xinput inside of virt-mang log Alt and 2.
Is it possible to configure xtigervncviewer, started in normal mode, that it works like in the fullscreen?

Found answer in the #2 . Patch from that issue works perfect.
