Cannot start the preferences application for your window manager

Post by grcutter » 2019/10/24 01:45:28

I am running Centos 6.10.

I have run into a problem with VNC sessions on my server: At some point the keyboard loses focus and I can't type anything into any window.
This will happen in particular if I start a vncviewer into another computer (double VNC).

I think that keyboard focus is set by the window manager but when I go into System -> Preferences -> Windows
I get an error message popping up with
"Cannot start the preferences application for your window manager. Window manager 'unknown' has not registered a configuration tool"

I am using gnome as the window manager.

How can I get a configuration tool registered or if this is not my underlying problem, how can I regain the lost keyboard focus?

Facing the same issue here too. Some help is appreciated.


Thanks in advance.

WHY might you even try such a thing with (essentially) nested virtual environments?
Multple login IDs are not your friend when asking for help!
