Troubleshooting • Re: Pi 5: display sleeps and immediately wakes back up

Code:

dtoverlay=vc4-kms-v3d-pi5

It's not the cause of your issue, but you should use:

Code:

dtoverlay=vc4-kms-v3d

which will work on any Pi (including pi5).

Try adding "vc4.force_hotplug=1" to cmdline.txt (on the existing line), and reboot. Any change?

Unfortunately that didn't change anything, I'm still getting constant loops of monitor sleeps/wakes. And like before, by initiating an ssh session to the pi and immediately terminating it, the issue would temporarily stop.
Another thing that I forgot to mention is that if I wake up the pi without logging in, then lightdm greeter (login screen) will never blank and sleep the display.
