Guys, I don't know if this is the new xorg sever upgrade or what, but after updates, X will not start on my archlinux guest in vitrualbox. I have reinstalled virtualbox-archlinux-additions (4.1.8-2) and still no joy. I get the following when trying startx: X.Org X Server 1.12.0 Release Date: 2012-03-04 X Protocol Version 11, Revision 0 Build Operating System: Linux 3.2.9-1-ARCH i686 Current Operating System: Linux tdepv 3.2.9-1-ARCH #1 SMP PREEMPT Thu Mar 1 09:10:44 UTC 2012 i686 Kernel command line: root=/dev/disk/by-uuid/ed9a0dc2-64b7-4e14-884c-bec2ad12f8d1 ro vga=0x31a Build Date: 05 March 2012 06:02:28AM Current version of pixman: 0.24.4 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.

Please also check the log file at "/var/log/Xorg.0.log" for additional information. So looking at Xorg.0.log I get: [ 51.021] (EE) module ABI major version (11) doesn't match the server's version (12) [ 51.028] (EE) Failed to load module "vboxvideo" (module requirement mismatch, 0) [ 51.037] (EE) Failed to load module "vesa" (module does not exist, 0) [ 51.050] (EE) Failed to load module "fbdev" (module does not exist, 0) [ 51.050] (EE) No drivers available. I have vboxvideo.so in /usr/lib/xorg/modules/drivers/, so I'm a bit stumped on the mismatch. Does this mean I have to install another version of virtualbox or what? -- David C. Rankin, J.D.,P.E.
