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_interaction_in_a_Linux_console_with_setterm 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.
