Ubuntu – After waking from hibernation/suspend, screen displays noise pattern

20.04graphicssuspendupgrade

This is how the screen of my Lenovo T410 appears when it wakes up from hibernation. Sometimes I see other noise patterns, but it never wakes up to the password unlock screen anymore. It doesn't react to any Fn, Ctrl, Alt key combination I've tried, and will only work normal again after a reboot. It also works if it's waking up from sleep (i.e. if I don't close the lid).

This started happening only after upgrading from 18.04 to 20.04. It looks like a graphics driver issue.

Do you have hybrid graphics with an NVIDIA card on your system? If so, maybe try installing the NVIDIA graphics drivers. I had similar problems which were resolved upon installing the proprietary NVIDIA drivers. Steps to install the driver

This might not be the best solution, but it seemed to work for me.
