#dpms — Public Fediverse posts

TIL: #NVIDIA hat noch immer Probleme mit Energiesparmodi. Hab ein System mit #Xorg (remote access und wayland ist noch immer no-go). Nach 10(?) Minuten geht X per default schlafen und schaltet per #DPMS den Monitor aus. Greift man nur remote zu, ändert sich optisch nix. Man sieht das Bild, kann entsperren und den PC nutzen. Also fast. Weil alle Programme mit Hardwarebeschleunigung durch VSync auf die FPS des "Monitors" gehen - und DPMS off macht bei NVidia 1FPS maximum. Die virtuellen Eingaben setzen dabei dem DPMS-Timer nicht zurück, lokale Eingaben würden ein Aufwachen auslösen. Lösung: dpms force on und per xset -dpms die Energiesparmodi abschalten.

I've noticed that at some point over the last several updates of Debian Testing / Trixie w/ Gnome that the lock screen now sleeps my screens properly.

Assuming some changes in DPMS handling has been added to the lock screen...

It's one of those things I never got around to digging into but, to whomever made code changes to make this happen automagically, Thank You!

I don't know if this is a 'net new' thing. I was on Debian Bookworm before and Pop! before that. Both were Gnome 43 (IIRC). And both didn't sleep my screens.

Created a gtk system tray icon to toggle #dpms and screensaver because I use #i3wm and it doesn't listen to whatever #dbus stuff is being send by firefox or vlc to do so.

Might actually investigate to have it listen to dbus

I assuming these messages go over dbus at this point but haven't verified

I still have no idea why my monitors turn immediately back on after going into DPMS idle but I have cut the phase space down a bunch:

Contexts where screens stay in DPMS idle:

• Windows 10 (this changed recently, it used to have the same problem)
• X + aterm, nothing else running, manual "xset dpms force off"
• X + aterm + mate-wm, nothing else running

Contexts where screens turn back on:

• Complete MATE desktop environment
• XFCE
• KDE
• niri

Things that don't affect the problem:

• Disconnecting either of the monitors
• Disconnecting the mouse
• Disconnecting the keyboard
• Which idle mode is used (standby/suspend/off)
• Using HDMI cables instead of DisplayPort (I think)

Please suggest more troubleshooting strategies for me to try, this has been annoying me for months and the only idea I have left is to plug more pieces of MATE in via .xinitrc until it breaks which sounds unutterably tedious

@gurkan seeing weird sub-2-minute behaviour here as well. Haven't figured out yet why. Blamed #KDEPlasma first, but there weren't any changes to its configuration.
