So this "fix" seems to cause Kernels released with zesty (and newer) keep the monitor always ON. No blanking, and no power down either.

Before this fix, a clean install of Ubuntu server would signal the monitor to sleep/standby after a short while. Now the default behavior is to leave the monitor always on, wasting power.

While blanking itself should be negligible to power savings and monitor longevity, sleep states are still an important feature.
