Does the system have a make and model?
Do you have the latest BIOS?

as shown in the attached file

Replying to the automated email and attaching a file doesn't work. You need to use something like imageshack to host the image and post a URL as an update

OK, you are right, here is the link to the "printscreen"
https://drive.google.com/open?id=1btonIBUAl02mIwxzR22rH8xHGUumWJaI
I hope you can access it
In any case I just wanted to inform you that the problem happens everytime I recover from suspend mode

Seems to be an older system. Latest BIOS is May 2011. Do you have this installed?

Another information that may be useful to solve the problem.
1. Whichever is the way I put the system in suspend mode, i.e. after a programmed time or with the power switch, after recovering in normal mode, the display is always damaged.
2. but if I rightclick the display in an empty space and I check the "change background" instruction, it accepts a good one, but not the previous, that is the standard Ubuntu 20.04.
3. After the dispaly is again a good one, I can change it again and resume the original one.
I hope this can help you, wizards of Ubuntu,
Thanks for the attention.
Claudio

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

Claudio Peretti (clauperetti) said : #13

The problem is still there.

After recovering from suspend mode, the screen is corrupted, as shown in
this picture:

https://drive.google.com/open?id=1btonIBUAl02mIwxzR22rH8xHGUumWJaI
<https://drive.google.com/open?id=1btonIBUAl02mIwxzR22rH8xHGUumWJaI>

It is possible to recover just right-clicking on the corrupted screem
and choosing another wallpaper. If the chosen one is not the same that
was corrupted, the screen will show a good picture.

After this, if the previous screen is chosen, it will come back correctly.
