[m2 mini] cannot resume HDMI display #276

Closed dkwo closed 3 months ago

dkwo commented 3 months ago

On m2 mini, running

uname -r
6.6.3-413.asahi.fc39.aarch64+16k

I was unable to turn on the (HDMI connected) display after resume. The resume was triggered by sway, as such:

exec swayidle -w \
          timeout 300 'swaylock -f -c 000000' \
          timeout 600 'swaymsg "output * power off"' resume 'swaymsg "output * power on"' \
          before-sleep 'swaylock -f -c 000000'

Is this a bug, or the result of misconfiguration on my end? Thanks.

it turns out this only happened because i turned off the monitor in between. if i let it go on standby, no issues.
