ubuntu 20.04 blank screen after suspend and/or closing laptop lid and reopening and/or logging in

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.

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

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"
