After new release of Virtualbox was installed and my virtual machine with OpenSUSE on-board had started, I've ended up with a dead keyboard. It worked fine on Windows XP as host, but OpenSUSE VM was acting like there is no keyboard at all. Couple of minutes of brain activity and finger work I've found that
/etc/X11/xorg.conf was replaced during Virtualbox Guest Additions update. Comparing
xorg.conf between two latest VB releases, I was able to get the keyboard working. Here is a fix:
1. Restore old
xorg.conf :
cp /etc/X11/xorg.conf.bak /etc/X11/xorg.conf
2. Add
Option "CoreKeyboard" to
InputDevice section of
Keyboard[0]
3. Add
Option "CorePointer" to
InputDevice section of
Mouse[1]
4. Add
Option "SendCoreEvents" to
InputDevice section of
Mouse[2]
5. Rename
Device option from
InputDevice section of
Mouse[2] from
/dev/vboxadd to
/dev/vboxguest
