[LightDM] Lightdm, x11vnc two seats: VNC keyboard/mouse input only works if seat is active

[Christoph Groß]

Hi everyone,

I have Lightdm setup to run two seats:

XBMC (Seat:0) which uses my monitor
xfce (Seat:1) which uses virtual terminal 8
This way I can switch between them using Crtl-Alt-F7/F8

I use x11vnc to connect to display 1 (xfce) via VNC:

/usr/bin/x11vnc -auth /var/run/lightdm/root/:1 -forever -bg -rfbport 5900 -o /tmp/x11vnc.log -display :1 -xkb

So far so good. I can connect via VNC to xfce but my mouse and keyboard input is not recognized if the display of my server shows XBMC. If I switch to virtual terminal 8 (Ctrl-Alt-F8) using the server keyboard then VNC will work. This is not ideal. I want XBMC to be always be displayed on my monitor and access xfce only via VNC.

There seems to be some kind of problem which prohibits keyboard/mouse input over VNC if the virtual terminal is not active on the host.

Any ideas?

PS: I used -dk -dp to check if the keyboard and mouse inputs arrive at x11vnc and they do. So that's not the issue.
