If I understand you correctly, it was the update within virtual box of Xorg 1.11 -> 1.12 that left the guest unable to start X due to the vboxvideo.so not being compatible with 1.12. With that information, then and knowing the vboxvideo.so was provided by virtualbox-archlinux-additions (courtesy of pacman), it looks like virtualbox-archlinux-additions needs to be rebuilt based on the new X. The question then becomes, if the new X breaks vboxvideo.so, what is it that triggers the packager to know it's broken and needs rebuilding? User reports? Some kind of automated ldd check? Just curious and trying to learn... - -- David C. Rankin, J.D.,P.E.
