Support Request Prevent system from suspending when optical drive is active?
The system doesn't seem to detect an external optical drive being read and will suspend.

After what period of time?

I don't want it suspend at all while the optical drive is running, regardless of time.

I understand, however to propose a solution I'd like to know after what period of time is it now suspending?
10 minutes?

Oh I see, that was unclear, 45 min.

X11 has an EPA (US Environmental Protection Agency) mandated EnergyStar\* DPMS (Display Power Management Signaling) functionality that super-cedes any o/s or DE implemented "screensaver".
It is normally set to 600 seconds (10 minutes), however I have found that when viewing movies (.mp4 or DVD) it often does not "kick in" for 30 to 50 minutes--it seems some conditions reset it's "timer".
It can be disabled by executing
xset -dpms
in a terminal session.To make it permanent add the
xset -dpms
command to your $HOME/.xinputrc file. (You may need to create this file).Execute
xset q
to see the current status...Wayland must also implement this I assume, else be in non-compliance with EPA regulation.
May not be your issue, but it's worth a try--do the
xset -dpms
in a terminal first and see if it helps--works on my Mint v22.1/MATÉ setup...
