[gentoo-user] Virtualbox Display Broken After xorg Upgrade

[Drew Tomlinson]

I'm not sure where to start.  I upgraded from xorg 1.4 to xorg 1.6.  I
also followed the ATI Migration guide at
http://www.gentoo.org/proj/en/desktop/x/x11/ati-migration-guide.xml.

Everything seems fine except now Virtualbox 3.0.2 guest displays are
unreadable.  Before the upgrade, Virtualbox displays were OK.  Basically
it looks like when one has a bad modeline for X.  If I click on the
guest window to close, I get a Virtualbox pop up asking if I want to
shutdown or power off the guest.  When this pops up, the screen is a
slightly readable black and white version.  Guest machines are Windows 7
and Windows XP.  Both have the same symptoms.

I've rebuilt virtualbox-bin and -modules.  I've Googled but can't seem
to find the right google-fu to turn anything up.

Any suggestions on how to get things working again?

Thanks,

Drew

Do you have the Windows vbox guest additions installed in the Windows
guests?  If so, you should be able to resize the guest window just like
any other X window.  Hm, not sure if the guest additions are available
for Win7 yet, but definitely are for XP.  Worth a try, anyway.

I know I installed them but maybe I did it when running Virtualbox 2.x. 
If I can't see the Virtualbox screens, how can I install/re-install the
guest additions?  Is there some way to do that from a command line?

Thanks,

Drew

That wasn't very clear. I was thinking that resizing the guest window
might make the out-of-sync Windows screen snap into sync.

Yes, your guest additions may be out of date now. At the top left of the
vbox guest window click 'Devices' and then 'Install guest additions'.
I don't recall if you need to be able to read the Windows screen to do
this, though.
