First of all, don't consider this a duplicate question since none of the existing solutions work for me plus I dont see anyone.

Issue : laptop screen remains black after suspending and/or closing laptop lid and reopening and/or logging in. Though I can't accurately reproduce the issue, I can gurantee that this issue occurs after suspending and waking more than 2 times. Laptop fans and backlit keyboard wakes up: so its only the display which is affected.

Additional info : system has an Ubuntu-Windows10 dual boot with both grub and uefi bios running peacefully without pissing of each other.

system info:

NOTE:

  1. The kernel is already the latest : so it's not that conventional amd issues with kernel 5.4 and/or 4.x.
  2. NONE of the existing solns stating ctrl+alt+{any function key} lit up the screen : so please dont suggest the same.
  3. Installing xscreensaver reduced the issue frequency, but didn't eliminate it completely.

Please someone help ASAP : I'm really stressed about this

  • Not really enough information to go on. I presume you have to hard power off and reboot to be able to use the laptop again? Can you go back in the syslog and look in the logs around the time it tries to wake up. Then edit your question and add these.

  • Please read this article & see if applies to you. I was able to fix the no-suspend lid close issue on Thinkbook 14 AMD completely & explicitly set HandleLidSwitch=suspend & it still works. lucraymond.net/2021/07/09/…

Reset to default

I've found a workaround

  1. Set "blank screen" to "never" in settings>power

  2. Set "automatic suspend" to "off" in settings>power

  3. Set "power button action" to anything other than "suspend" in settings>power

  4. The most important : Open logind.conf file in etc/systemd using gedit

sudo gedit /etc/systemd/logind.conf

Then uncomment (remove the #) the line containing "HandleLidSwitch" and set its value to "ignore"
