Comment 0 for bug 43825

After starting `sudo input-event -g 6` within gnome-terminal under X, and pressing each successive key on my default keyboard (mapped to /dev/input/event6), the system stopped responding, the USB power stopped, and the monitor went into standby mode. The machine was unresponsive to network activity, and no input devices had power, although the internal fans continued to run.

Pressing the power button for a short period (ACPI soft power) had no noticeable effect. A hard powerdown and reboot restored all services normally.
