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.

Thanks for trying Helen. However, I should have mentioned that I have 
rebooted many times since this problem began.

I have also just done ...
sudo stop lightdm
sudo start lightdm
... as you suggested.

Unfortunately, it's all still broken. Not bars above any of the windows.

Has anyone seen this before?

Thanks,
Damian
