I have encountered a lot of problems keeping X working lately, and upgraded my kernel today to fix this.
As a result, I am getting very poor performance as the X process is taking all the CPU resource it finds.

Below are the related information:

Code:
$ glxinfo |head -n 6

Last, I have the following options in the kernel:
Code:
CONFIG_DRM_VBOXVIDEO=m
CONFIG_VBOXGUEST=y


(without this, virtualbox-guest-additions would not even compile).
