64 bit guest in seamless mode

[drb1]

I have a 64 bit debian based host and have no issues with virtualbox 2.1.4 with a 32 bit debian guest and a 32 bit windows xp guest . . . but when I install a 64 bit debian guest I can not get it to operate in seamless mode (greyed out in menu). Is this a general issue or am I doing something 'wrong'. As I say, 32 bit debian guest has no issues running seamlessly

Check if your xorg.conf is exactly the same as your 32 bit Guest. If you don't have Seamless, it also means you don't have dynamic resizing. And if you don't have that, the GA are either not installed properly, or your xserver is not configured properly (dynamic resizing is disabled when a resolution is found since 2.1.4 GA).

Thanks Sasquatch - there are differences in the xorg.conf for the two installs : does this indicate the problem? What should I change to get seamless, dynamic sizing?

First is the mouse. The 64 bit Guest doesn't use the vboxmouse driver. That prevents seamless mouse to work, so you have to click inside the Guest to grab the mouse and hit the Host key to release it. The easiest way to get this working properly, is to copy the xorg.conf file to the Host using Shared Folders and then transfer it the same way to the other Guest. Or if you use Host Interface, you can use SSH scp (available if you have OpenSSH-server on one of them, or both) feature to copy it directly.
