I would like to run winswitch on two current ubuntu (oneiric) boxes, both running the vinagre/vino-server VNC client/server combo. The 'Desktop Default' section in server configuration ui reads 'None available' (ui/config_server.py: populate_session_types()), and 'Start Desktop Session' is disabled.

I tried trivially adding the vinagre/vino paths to VNC_COMMAND/XVNC_COMMAND in util/commands_util.py; that did not work.

The problem persisted even after installing the tightvnc viewer.

Any hints would be appreciated.

Thanks!

I'm using winswitch 0.12.14 in server and client-side, and NX protocol to open Desktop sessions. However, every time I resume a session the keyboard settings is not set and I need to execute the following command to fix:

$ setxkbmap -layout us -variant alt-intl -print | xkbcomp - $DISPLAY

I'm seeing the following error trying to connect from a 0.12.17 client on lucid to a 0.12.17 server on gentoo:

The connection shows up as successful, but no applications or sessions are available. This problem also happens with 0.12.16, but goes away if I downgrade the client to 0.12.15.
