Linux Mint install with graphics problems

[greedyiguana]

Hey guys,

I am currently running a Windows 7 x64 host and installing a Linux Mint 32 bit guest. The problem I am having is that after the installation (which goes fine) and installing VBoxGuestAdditions (which also works fine) I have been getting some graphical errors that do not occur in a similar standard Ubuntu 32 bit guest. For instance, I have a dual monitor setup, which I will usually use as one for the host and one for the guest. In Ubuntu, when I am doing something in the guest, and click over to do something on the Windows host, I click on the other monitor, type something, and everything looks fine. In Linux Mint however, when I click over to do some work in the host, the entire screen turns black, preventing me from seeing what I was working on in the guest system. Furthermore, when I click back, the only part that gets refreshed and stops showing just a pure black screen is whatever window I clicked on to make active. To refresh the whole screen, I have to do something like click and drag one window into every part of the screen. And this happens every time I switch focus from guest to host which is actually quite a lot.

Does anybody have an idea of what might be causing this problem? Or how to fix it?

Thanks!

This usually happens when compositing is enabled in the guest. Try disabling that and see if it helps.

i have a similiar problem.

If is us LMDE or Linux Mint 10 full screen, the little VBox menu, which is usually at the bottom, disappears.
If i want to minimize the VirtualBox Windows i always have to switch to WindowMode via "HOST-F" and minimize.
And back via "HOST-F" again, to switch to full screen.

In that case i also get a black screen, just some random spots at the screen, usually where my mouse is o smt will be displayed.
If i change desktop via "Ctrl+Alt+LEFT" everything will be displayed again.


edit: i think i have to say, that i us compiz. im also not shure what compositing is?!
but, everytime i used some ubuntu version in a VBox, i got non of these problems, also with full desktop effects activated?!
