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: askubuntu.com/questions/1405262/…– TommyPeanutsCommented Mar 16 at 9:02

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 ubuntu.com/server/docs/nvidia-drivers-installation or try upgrading or downgrading using the "additional drivers" tab in "software & updates".– TommyPeanutsCommented Mar 18 at 8:25
