Output from strace -r xset dpms force off
Running xset dpms force off turn off the display causes a spike of kernel-mode
CPU activity and around 1 second of system-wide latency (repeating sound from
the audio buffer, etc.).
The following kernel, xorg driver and libdrm versions are installed:
kernel-2.6.29.4-167.fc11.x86_64
xorg-x11-drv-intel-2.7.0-7.fc11.x86_64
