Hi,all
I compile the kernel-4.9.38 with xenomai-3.0.5,then I run latenct test.
I use ubuntu16.04 desktop to do these,however,the latency is sometimes up to 80+ us.
Also, I close lightdm and enter none-desk to run latency again,it's perfect that the latency is under 15us.
But I want the desktop with small latency,anyone has ideas for me?
BestWishes,
demon.
