Public bug reported: For the last few weeks, my desktop screen fails to blank after the timeout set in gnome-control-center. Blanking works properly after a reboot but then - especially after resuming from suspend - it will randomly fail to do so, either persistently or intermittently.
I am currently using gnome-control-center 1:46-4 but the issue was already present with the previous version. Video driver is nvidia- driver-550 from the ubuntu repositories. I suspect this may have to do with kernel code (too.) I did not experience this problem until I updated to the latest 6.8 kernel (I believe that is 6.8.0-48). I have since updated to 6.11.0-1007 but this has not made any difference. On a side note, I seem to be experiencing issues with all nvidia 5xx drivers. 535 fails to resume from suspend and 555 only gives me wayland. When I install 560 (from the graphics-drivers ppa), I get a kernel crash when I resume from suspend. I do not know about 555 and 560 but 535 used to work fine.
