Slackware 15 stable. Anyone know how to stop hibernation?

I'm not sure, but if I leave the laptop unattended for 15 minutes, I have to close and reopen the lid (or press the power switch) for it to show the login screen again. The same thing happens if I close the lid while logged in.

On my desktop, I can wiggle the mouse and have the screen come back to life.

"Hibernation" is not appropriate, we should have been more precise
Suspend to RAM (S3, aka "Sleep") can work out-of-the-box, indeed
Suspend to Disk (S4, aka "Hibernate") must be configured to work

Hibernate is like a poweroff / boot sequence but instead of starting from fresh, it resumes the last opened session
It's the most saving power mode. I don't know, but at this point I prefer poweroff and start from fresh

Any ideas would be appreciated.

Honestly it's a massive mess. upower/elogind/screensavers/powermanagers, xset/tset, ... all fight and interfere with one another for control, there are hidden/hard to find settings to configure who does what, plus plenty of dbus/policykit/systemd shenanigans and complexities on top. Plus all the *d bugs we've come to know and loathe.

Easiest if you want to completely disable all blanking is to configure elogind/xset to do nothing, then uninstall/disable all the screensavers and power managers.

for xfce4 sessions that means disable/remove:

xscreensaver
xfce4-screensaver
xfce4-power-manager

/etc/elogind/login.conf: (the default)
IdleAction=ignore

and if you need it, in ~/.xprofile
xset s off

I don't know if this is still the case but Slackware used to use APM to blank the screen when NOT running X. It would cause me all sorts of aggravation to try and disable the screen saver in XFCE only to forget about APM.

I think ACPI is doing it in your case.

I also think your solution is in this thread-

Specifically this part:

Code:

xset -dpms
xset s off
xset s noblank
