Anybody got experience with VirtualBox's Guest Additions with an Ubuntu guest?

My host is Snow Leopard. I'd like to do full screen virtualizations. For this, you need to install the Guest Additions. Linux Mint, which is based on Ubuntu, works fine: I get a nice full screen guest machine. But for Ubuntu, the full screen guest is dysfunctional: menus don't pull down or clear correctly, for example

1. The following page may be useful for certain Guest Addition installations in Virtual Box:

These directions appear to allow Guest Additions in Fedora

2. I have experience with the Guest Additions ...

I didn't experience any problems. Of course, the host was another Linux distro, which may have been a factor.

This is completely unhelpful, I realize.

The only real problem I've experienced involved a Vista guest, and it did exhibit the type of behavior you illustrate. I played with various settings, but the only thing that improved the situation was increasing the memory available to the guest's video RAM. I don't think this would apply to your situation.

3. The Ubuntu problem may have resolved itself after several virtual reboots. I have nagging

in the back of my mind some idea that I saw something similar on an Ubuntu installation on another of my machines: certain modifications and update behave as if the first reboot merely loads them into a critical location and a second reboot is required to actually apply the change. That might be a plausible safety feature for certain core updates, that allowed two-stage checking

The Guest Additions seem to work rather well for Fedora, Mint, and Ubuntu -- perhaps a little better for Fedora and Mint than for Ubuntu. I'm having some problems with Puppy

I suppose if I ever buy Windows 7, I'll try to see if I can get it to work well in Virtual Box: if so, I may not actually install it on a hard disk

4. Part of the problem may be this: Guest Additions are known to be buggy with multiple monitors

5. Rebooting my machine with one monitor turned off made the situation for Ubuntu

in VB with full screen mode even buggier
