BLFS in a Virtual Box guest... trying to get Xorg7.2 to run
I've built LFS 6.4 in a VirtualBox virtual machine. (VBox 3.04)
I'm now working on BLFS 6.3. I've built Xorg 7.2.0 and I'm at the point where I run "Xorg -configure" as root to build the base config file.
It exits with the error "Missing output drivers. Configuration failed."

I had compiled the kernel with a good mix of the most common drm drivers, and compiled all of the Xorg drivers except the Sun SPARC drivers.
I can't find any documentation on what the specific virtual video hardware VBox is presenting to the guest OS. I found that the virtual sound hardware is the ICH AC97 which was originally part of the Intel I810 chipset, so I tried recompiling the kernel with the I810 drm driver, and recompiled the Xorg drivers. I still had the same results.

I have also tried installing the VBox guest additions, but Xorg still says the output drivers are missing.

Has anyone out there got Xorg working properly in a Virtual Box BLFS build?

I don't remember exactly what I had to do to get it working, but the driver name listed in "Device" section of xorg.conf is "vboxvideo". Also, there should be a file called "" in /usr/X11/lib/modules/drivers.

Hope this gives you some clue.

Thanks mjones. That got me closer. Now I need to figure out which mouse driver and protocol will work for gpm and xorg.
