Massive Xubuntu desktop malfunction

You need to have the program xfwm4 run on startup.

To do that, add a program to the login items.

To add a program to the login items, open up the session editor (Applications Menu > Settings > Session and Startup), switch to the "Application Autostart" tab, and then add a new item:

Click "OK", and you should be good to go.

Also, if you could file a bug (For more on how to do that take a look here) that'd be great.

I have found steps that fix the bug without any hacks:

• delete the content of ~/.cache/sessions/
• remove additional startup item for xfwm4 (if created as suggested by 'jrg')
• reboot PC

These steps were suggested to me when I reported the bug https://bugs.launchpad.net/ubuntu/+source/xfce4-session/+bug/1277738
