Display does not turn on from suspend #78

Open GuidoBartoli opened 5 years ago

GuidoBartoli commented 5 years ago

Describe the bug If the screen is turned off because of suspend (power management), when the PC is woke up from sleep, the screen does not turn back on. The only solution is to disconnect and reconnect the HDMI cable. This did not occur with the previous Linux Mint 19.1 version.

To Reproduce Steps to reproduce the behavior:

  1. Go to Preferences --> Power Management
  2. Enable "Suspend when inactive for..."
  3. Set a timer to any value
  4. Wait for the computer to go to sleep
  5. Wake up the computer pressing any key

Expected behavior The attached monitor should turn on.
