How to prevent system from suspend when camera is on? I tried to use Caffeine which works great for all the apps which I know the process name. However, when I’m on the meeting via Firefox/chromium sometimes after 20 minutes my computer suspends. I use lightdm with Awesomewm.
Hello @lukastymo and welcome
Do you mean it goes into deep sleep mode (S3) after 20min? Never heard, it would even do this by default… But I believe you mean the screen suspend time, then I have an idea for you:
I was also annoyed by this default 20min standby behavior when using suckless dwm, so i just created a file and increased it here:
Section "ServerFlags" Option "BlankTime" "15" Option "StandbyTime" "30" Option "SuspendTime" "45" Option "OffTime" "60" EndSection
The numbers are minutes.
If you need it really only for the camera, then use a udev rule.
