I need to be able to use VNC to view and control my Macbook Pro. Unfortunately after upgrading to Lion all I get when I VNC into the machine is the following screen
Lion%20Broken%20VNC.PNG


Very useful, and a complete show stopper for me. I have tried fiddling with all screen sharing and remote admin options to no avail. Trying different clients makes no difference either.
 
Unfortunately not. I've had to fall back on my Snow Leopard backup for now. Perhaps I'll try again in a few months. In the meantime I have submitted this to Apple as a bug report.
 
not working for me either from XP via VNC - tried ""Only use protocol 3.3"" but this didn't solve anything - setup mac for screen sharing (not remote control)

interestingly in the system log, after I try to connect with VNC (nothing else) I see the following - there are some logmein lines in there for some reason (also noting logmein is busted under Lion for the moment too...)

I never used VNC before. But one particular program gives you a keypad on the iPad to control a music notation program on the Mac. I downloaded it and confirmed the connection to the Mac. But the buttons did not work at all.

A note from the developer told me that Lion has added a new wrinkle regarding VNC connection; you must be logged out before making that connection. When when you log back in it will work. And it did.

I have no idea if that's at play here, but it seemed to take people by surprise on the 'Sibelius' board.
 
Yeah logging out can be used as a workaround, but not if you want to have programs running on the machine while you aren't logged in via VNC, e.g. downloading something or encoding a file

Still broken now in May 2012!

Same issue here -- intermittently. I suspect the destination Mac is asleep, anytime anyone goes and does anything to it, after that, it connects OK. Until the next time it's been neglected.
 
and easy answer --- set up the built in ScreenSharing and it works fine.
 
After login on gray screen , type your name and password [ ( both case-sensitive) and it works ( at least for me) ]
 
Sky Blue: That makes sense, in my opinion, is login window in Lion already, although not visible --> Due this my solution works ;)
