I had to upgrade NVidia proprietary driver to 545.29.06.0 in order to play Ghost Of Tsushima Director'S Cut. Now I can't use suspend anymore, cause on resume I get black screen and mouse cursor. Only tty works.
NVidia forum confirms it's known bug? in that driver version:
They suggest upgrading driver to never version, and in repos there is none.
Does this only happen when it goes into automatic sleep?
Does putting it to sleep manually also happen?
I ask because this happened to me, but only in automatic suspension.
After some research I discovered that it could be something related to the external monitor, which was turned off before going to sleep and then couldn't come back on.
What I did was configure the monitor not to turn off before going to sleep. In the energy schemes it is possible to make this change.
After making this change this never happened again.
