[tde-users] How to automatically "Suspend to RAM"?

Dear all,

I am a long-time and happy user of the Trinity desktop, which is a wonderful continuation to KDE 3.x. I am try to sep up my laptop to automatically "Suspend to RAM" after a given time without user activity, but i can't figure out the setting.

Could you please give me some pointers?

The configuration: Thinkpad T400 (RAM 4go) Q4OS 3.15.2-n1 (Debian 10 Buster-based, 64bit distribution)

The following interactive commands work: sudo systemctl suspend sudo bash && echo -n "mem" > /sys/power/state

Best regards
