Ubuntu shows blank screen after waking up from suspend (dual boot)

in flag

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?

Additional info about system:

uname -a and inxi -Fxxxz

lspci -knn | grep -EA4 'VGA|3D|Display' and hwinfo --gfxcard

hwinfo --gfxcard

neofetch

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.

@ShirinJZ - I will check. Please consider copy-pasting as (markdown formatted) text, not screen captures. That is essential for further searching. It makes it easier for others to help you.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
