Keeping the Screen Turned off While Getting Inputs

[Ahmad Nouralizadeh]

 I want to count the processor-initiated memory accesses. On my 4K display, a huge number of accesses originate from the iGPU and dedicated GPU. I want to exclude these accesses. The IMC counter can only track the dedicated GPU accesses. Therefore, I have to turn the screen off to exclude those originated from the iGPU.

Can I ask why? What is you're trying to accomplish? Somehow affect the
benchmarks? Stop people seeing the benchmarks being performed?

And what is the benchmark measuring? Elapsed time or CPU time or what?

Turn the display off and run the benchmarks by ssh-ing in from another
machine?
