No DBus signal available for Wake event in linux

vipul.g · 01-04-2024, 02:26 AM

I wanted to perform some task in my application, as soon as the application wakes from sleep mode. To do that I wanted to detect the wake event in my application.
In the 'org.freeDesktop.login1' interface, there is a signal 'PrepareForSleep' available to detect the sleep event, however, there is no counterpart DBus signal available to detect the wake event. Either it is not available or I m not able to find the signal.
Can someone help me?

Please post which linux version you are using.

Without further information this may, or may not, relate to your problem...

My problem is with my new monitor [LG 24ML600M - B].

My computer starts up, then IF before log into computer within a few minutes it apparently decides to go into sleep mode...

Self needs learn how the Monitor can be awakened...
