I have a dual boot system. When my ubuntu suspends, after waking up it shows a blank screen; I've tried multiple solutions but wasn't helpful. :( This is my ubuntu description:

Description:    Ubuntu 20.04.3 LTS
Release:    20.04
Codename:   focal

Does anybody know what I should do?

More info on your system is needed. I will post a few commands to help with this. Plus a few tentative solutions.

Additional info on your system

Please post, by exactly copy-pasting both the commands you enter and the output you get of the following:

$ uname -a
$ inxi -Fxxxz
$ lspci -knn | grep -EA4 'VGA|3D|Display'
$ hwinfo --gfxcard
$ neofetch

You might need

$ sudo apt install inxi hwinfo neofetch

Possible solutions

  1. Configure driver options at boot time. For instance, if using the noveau driver, add modeset=0. See here. I will wait for your further info.
  2. Ctrl+Alt+F3 and back with Ctrl+Alt+F2, as a temporary solution.
  3. Updating graphics driver.
  4. Try with sudo systemctl suspend, and then waking up. See here.
  5. Try with sudo pm-suspend, and then waking up.
