[mythtv-users] Backend window manager messed up

[Damian]

Hello all,

I'm running MythBuntu on my home server's backend. The server is in the 
garage and I access it via primarily via VNC.

For a few weeks now, the window manager (Xfce) has been messed up. When 
I log into VNC, it looks 'kind of' like it usually does, but there's no 
visible panel at the top (although I think that's just because other 
windows are in front of it rather than below it) and the other windows 
on screen (Firefox, SpiderOak, TeamViewer etc) don't have a top bar. The 
bar that you use to move, close, maximise and minimise a window. Those 
top bars are simply not there.

Most things seem to be working ok with the server. The MythTV backend is 
functioning fine. My music server (Logitec Media Server) is working 
fine. I seem to remember that Dropbox stopped working, for some reason, 
a week or two before this problem started, but I didn't worry too much 
about that.

So, it's household function is 'OK', but I can't do anything else on the 
machine because the GUI is messed up.

Do you lovely people have any idea how to fix this?

Thanks,
Damian
