Describe the bug
After installation with default Intel iGPU setup, when going to sleep for the first time on a cold boot, the device wakes up normally with internal display ON. On second sleep wake, the internal display cannot be turned on. Here, plugging into a usb-c monitor will trigger the internal display to power on.

To Reproduce
Steps to reproduce the behavior:

  1. Sleep the device by closing the lid
  2. Open lid to wake
  3. Sleep the device by closing the lid again
  4. Open lid to wake again
  5. See error
  6. Plug in usb-c monitor
  7. See internal display turns back on

Expected behavior
Device should be able to wake internal display again without external aid
