Installed TightVNC on my B+ and then installed on two Windows machine (W7 and W8.1).
All seemed to be going swimmingly until I tried to close the Pi down.
It refused to fire up a terminal window (as an aside the shut down button on the tool bar at the bottom disappeared a little while back) and also refused to fire up the shut down prompt from the desk top icon.
I ended up shutting it down remotely using a terminal window.
Now when I boot up it appears to try and start a graphical interface, then drops back to a white screen with a login prompt.
If I log in here then it again tries to do something, and then fails and falls back to the white screen.
I haven't installed VNC to run on boot (as far as I know) so can't use that to put my hand up the Pi's back.
Haven't tried to ssh in. I've very little invested, so I may just put a new build on and go from there.
So, has anyone had similar problems with VNC?
