Virtualbox is a virtualization product: a software which can "emulate" machines and run Operating Systems and programs on them with near native performances. 3-D acceleration is one among the many features offered by Virtualbox; a feature included with release 2.x of the software.

Given a Host system with '''3-D capable hardware''', a correctly configured virtual guest system can use 3-D graphic acceleration.

The installer program will automatically compile and install the needed kernel modules. Each step will produce a verbose output on your console. At installation conclusion, try to run a graphical session. The X server distributed with Slackware 13.1 should start without a /etc/X11/xorg.conf configuration file. If problems arise, create the configuration file by running command xorgsetup and answering some questions concerning your hardware and preferences. The xorgsetup command will scan your hardware and save a proper xorg.conf file in directory /etc/X11.

Some Linux distributions require no additional step. Slackware on the other hand, due to some discrepancies in the driver and libraries installation paths, needs some tweaking to enable the graphic 3-D acceleration.

1 – Low framerate. When running the ''glxgears'' program, the returned frame rate never exceeds 300 frames per second. 300 fps is a real low value and a direct consequence of software 3-D rendering.

The message is a self explainatory one. It states that since no proper driver was found the system reverts to software rendering.

To solve the issue you need to create two links in order for Virtualbox to find the needed drivers. From a shell prompt run:

Last but not least verify that creation rules for the Virtualbox device drivers are not root centered. Check for file 60-vboxadd.rules in directory /etc/udev/rules.d. The file should exist and contain two lines:
