I need to run a set of (**graphical**) **benchmarks** with the screen **disabled**. The following command did **not** work:

    xset dpms force off
Because any keyboard/mouse **input** would **re-enable** the screen. The **other** option was the following:

    xrandr --output eDP-1 --off
This turns off the screen for a **second**, then, causes the following **segmentation fault**:

    gnome-shell[25737]: segfault at 8 ip 00007f3d02ef9210 sp 00007ffeee4e1fd8 error 4 in libmutter-2.so.0.0.0[7f3d02e99000+156000]
How can the problem be **solved**? Is there any **other** user/kernel level alternative?
