All, I have 2 Arch servers that boot to the default text console. It has always properly blanked (DPMS power off) after the default timeout (6-7 min?). After update to the 4.12.5 kernel, which occurred at the same time of the xf86-video-ati (1:7.9.0-1 -> 1:7.9.0-2) update, the monitor no longer powers off when the screen blanks. An hour later there is still the blanked-but-powered light from the monitor (I don't know if this is called backlight power for the text console rather than X). The problem continues after the 4.12.6 update. So there was either something in the 4.12.5 kernel update that is preventing the console power-off from working, or something in the xf86-video-ati update that did it. There is nothing in the journal about video or dpms. What else can I check to help figure out what broke? With X at least there is xset, but I'm not sure what to look at for the default terminal? -- David C. Rankin, J.D.,P.E.
