Hi,
I could not catch your idea about the GPU usage patterns. How
could I acquire this information?
My laptop model is Dell Latitude 5501 runing over ubuntu 14.04
system.
GPU model information： NVIDIA GeForce MX150.
NVIDIA... using their close-source driver or nouveau?
It's been a long time I ran that on a Xenomai box, I only vaguely
remember that there used to be issues with lengthy cache flushes when
data is pushed to RAM in order to make it visible to the GPU.

It's not X11, it's the side effects of certain GPU usage patterns on
your particular platform. Can you specify more details about both?
