Suspend issues with nvidia proprietary driver

[Lorenzo Ranieri]

When I suspend my system, after the screen goes black, the desktop and the suspend login screen are briefly shown in succession, and only then the screen, power LED and fan turn off like normally.

The timing of the brief "fake resume" is not consistent: sometimes it only shows the login screen, sometimes it stops the suspension until briefly after I login.

When resuming after this has happened, the login screen appears as normal, but I have to wait for any internet connection to restart, and my second screen remains blacks despite it being detected and the display mode remaining on "join displays", until I change the display mode back and forth to fix it.

These issues occur after switching to the nvidia-driver-470 driver on a fresh install of Ubuntu 21.10, but I have been experiencing at least the "fake-resume" since at least 20.10, without being able to find any solution.

These issues persist (with slightly altered timing) if I switch to an older proprietary driver (I tried nvidia-driver-390 and nvidia-driver-460), but do not appear while using the nouveau driver.
