The Current factory doesn’t work doesn’t play nicely with Virtualbox 4.3.14 in that Xorg X11 1.16 isn’t yet supported by guest additions so you are stuck with a fixed screen. However there is a fix here:
Hm. Strange enough the openSUSE packages already contain the (upstream) patch to build the vboxvideo driver for Xorg 1.16.
But still, the driver fails to start because it requires ABI version 17, whereas Factory’s Xorg has ABI version 18.
I’ll have to investigate. I think the problem is that the spec file only installs the driver for 1.16 “%if %suse_version >= 1320”, but Factory’s %suse_version probably is not >=1320, so the default 1.15 driver gets installed.
The updated virtualbox-guest-x11 package is now in Factory.
So there should be no need any more to manually download and install newer guest additions.
Factory’s vboxvideo driver should work out of the box again with Factory’s Xorg.
[QUOTE=jonte1;2659200]I confirm, working on openSUSE-Factory-DVD-x86_64-Snapshot20140805-Media.iso
Well, that snapshot doesn’t contain the working vboxvideo driver yet.
It should be in the current one (20140813) though, and all subsequent ones of course.
So it should work out of the box in all snapshots starting with 20140813, even the LiveISOs.
