Public bug reported: 1. Have Power Management preferences 'Put display to sleep when inactive for..' to something other than 'never'.
2. Leave computer for longer than that. 3. Come back to find computer still running, but display will not resume after pressing a key / moving the mouse. Possibly related to playing video (see https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics- drivers-435/+bug/1852570) because it doesn't happen every time, but has happened at least four times since upgrading to Ubuntu MATE 19.10 with this version of the graphics driver. On the most recent occasion, syslog contains numerous lines like: Nov 17 18:42:11 example org.mate.panel.applet.MateMenuAppletFactory[1267]: [2737:2737:1117/184211.847879:ERROR:gles2_cmd_decoder.cc(5755)] GLES2DecoderImpl::ResizeOffscreenFramebuffer failed because offscreen FBO was incomplete.
