This sounds like it may be graphics card related. Can you give any details on what graphics hardware you have in the laptop? Also, this may be helpful: https://askubuntu.com/questions/1405262/how-to-solve-black-screen-after-suspension-with-ubuntu-22-04-lts – TommyPeanuts Mar 16 '24 at 09:02

It may be you need to find out whether a specific driver needs to be installed for that. Try following the instructions here to see if that helps https://ubuntu.com/server/docs/nvidia-drivers-installation or try upgrading or downgrading using the "additional drivers" tab in "software & updates". – TommyPeanuts Mar 18 '24 at 08:25
