PPS: A few days ago I tested a LCD monitor. Screen blanking already caused the monitor to completely power off (after hat it was needed to turn on the monitor by the monitor's power button). Perhaps you changed some Eco settings of your monitor? Maybe your monitor powered off triggered by screen blanking and now it doesn't do it anymore?
Ralf,
Thank you for your suggestions. I'll go through the DPMS page again. I haven't change a single-thing on my system, so Eco setting, no monitor settings, no nothing. Past 7-8 years same config, monitor always powers down, as soon as the updates went in on 8/11, DPMS just quit working for the text console. Crossing-fingers the DPMS has a hidden nugget somewhere inside :)
Ralf, all, I can use 'setterm --blank 3 --poweroff 4' to have the screen blank and poweroff just as it has always done since 2009 up to the 4.12.5 kernel and xf86-video-ati 1:7.9.0-2. Now for the first time I am having to manually set it. What changed? Why should I now have to manually use 'setterm' where before this was automatically set to a reasonable default? Does anybody know if this is an Arch change or an upstream change? /etc/issue has not changed in months, e.g. $ l /etc/issue -rw-r--r-- 1 root root 20 Mar 26 16:57 /etc/issue How do I set a default for the system so all of the text consoles VT1-6 automatically poweroff? I see the "Bash loop to set ttys 0-256" in the DPMS wiki: https://wiki.archlinux.org/index.php/Display_Power_Management_Signaling#DPMS... but having to put that in a profile seems like a cludge. /etc/issue apparently can be used for preventing blanking/poweroff, but is this the correct file for setting the poweroff systemwide? The http://webpages.charter.net/dperr/dpms.htm link doesn't address system config (just how it works) Thanks for any wisdom on this topic you can provide. -- David C. Rankin, J.D.,P.E.
