Public bug reported:

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
Description:    Ubuntu Hirsute Hippo (development branch)
Release:        21.04

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
powerdevil:
  Installed: 4:5.21.3-0ubuntu1
  Candidate: 4:5.21.3-0ubuntu1
  Version table:
 *** 4:5.21.3-0ubuntu1 500
        500 https://mirrors.tuna.tsinghua.edu.cn/ubuntu hirsute/universe amd64 Packages
        100 /var/lib/dpkg/status

3) What you expected to happen
When the laptop lid is closed, after screen timeout is reached (Settings-Power Management-Energy Saving-On AC Power-Screen Energy Saving-Switch off after), open the laptop lid, laptop display should automatically turn on.

4) What happened instead
Laptop display won't automatically turn on after opening the lid, instead mouse or keyboard interactions are needed to turn on the display.
It seems the bug is related to Wayland, for the bug doesn't appear in X session.
