XBMC, libGL error: failed to load driver: i915

I am a brand new Linux user, and while installing XBMC I received this code in the terminal:

libGL error: Version 4 or later of flush extension not found
libGL error: failed to load driver: i915
Running DIL (3.22.0) Version
DtsDeviceOpen: Opening HW in mode 0
DtsDeviceOpen: Create File Failed
libGL error: Version 4 or later of flush extension not found
libGL error: failed to load driver: i915
libGL error: Version 4 or later of flush extension not found
libGL error: failed to load driver: i915

XBMC runs, but I am worried that the video drivers are not installed properly, and I am at a bit of a loss as to where to begin.

Thanks for helping!
