Thanks for the suggestion to upgrade the BIOS. The laptop is brand new, so I did not think the BIOS would be out of date.
I did the upgrade but the problem persists. Strangely, after opening the lid, the mouse cursor appears on the login screen (the session is automatically locked when the lid is closed). After unlocking the session, it disappears as said previously. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1573760 Title: screen remains black after hibernation or suspend to RAM Status in xserver-xorg-video-nouveau package in Ubuntu: Confirmed Bug description: I just installed XUbuntu 16.06 on my laptop. Suspend to RAM and hibernation seem to work correctly, but resuming from either of it is not actually possible because the screen remains black.
