So maybe you’ve heard something I haven’t, according to this timeline, there was only 2-3 minutes between when the ship issued a mayday and the bridge collapsed: https://www.cbsnews.com/news/francis-scott-key-bridge-collapse-timeline-911-call-dali-cargo-ship-mayday-maps-construction-worker-recovery/
It sounded like there was 1 police officer already stationed on either end of the bridge, so thats the only reason they were even able to close the bridge before the collapse.
In the time it took them to do that, I can’t see how there would have been time to warn them physically (it’s like a 2 mile bridge). From the article, it sounded like there was confusion about if a crew was even on the bridge. I also don’t know how often / what mechanism police can use to directly contact crews, if there even is one.
I know for me, at least with gnome, toggling between performance, balanced, and battery saver modes dramatically changes my battery life on Ubuntu, so I have to toggle it manually to not drain my battery life if it’s mostly sitting there. I don’t know if Mint is the same, but just throwing out the “obvious” for anyone else running Linux on a laptop.
