Reference: screen sharing in Snow Leopard

Posted originally for my personal reference, but since my Mac tips get lots of Google hits hope this is useful to you too.

Screen Sharing on Mac OS X Snow Leopard – very convenient to have built-in*, and I use it to logon to my Ubuntu server when the CLI doesn’t cut the mustard – infrequent, but it happens.

If you’re like me, you occasionally get an unexpected blank or white screen when you connect to your other computer. It turns out the mouse and keyboard pass through just fine but the display is all white. Fix it by getting info on Screen Sharing.app and ticking the ‘Open in 32-bit mode’ box.

* Technical addendum: I would be remiss to sing accolades of the VNC-based Screen Sharing without mentioning Microsoft’s [Citrix] Remote Desktop. It’s significantly faster than VNC due to some sweet implementation differences – to my knowledge when you connect to the Windows host it switches to a special display driver that sends small drawing instructions over the tubes that are subsequently recreated on your client. VNC, while open source and commensurately ubiquitous in Unix/Linux/Mac land, is not so smart and blindly sends a compressed image of the screen. Just sayin guys – Remote Desktop is awesome.
