I noticed that when close the lid and reopen the system is still working and all of a sudden it appears a login screen and when login all programs as killed as it was logged out. And most of times after login it locks and prompts an unlock screen. I tried to switch to nouveau driver and the problem seems not to happen, but that leaves me with a poor performance in terms of graphics. I tried to reset the setting in dconf using dconf-editor to reset the system recursively, at the beginning seems to be solved but it gets back. I need to mention that I faced the same problem when using budgie flavor, I thought that it might be a budgie problem but it appears to be a gnome problem since budgie is based on gnome and on both the problem happens when using Nvidia drivers.
