Networking :: Network disconnect is freezing my systems - v4.1



It depends on your keyboard, not software. It's either it's own key, usually next to Print Screen, or combined with a key, again usually Print Screen.

For example on the laptop I'm on currently it's combined with print screen, and used as alt + printscreen.

Thanks curaga!  I found it.  All these years, I've been wondering what that does.

OT: Anybody know what the "Scroll Lock" does?

What is emergency sync?

Does emergency umount unmount everything?

Emergency sync is just a sync that has highest priority, and emergency umount unmounts everything it can, and remounts the rest read-only..

In Linux Scroll Lock is the equivalent of windoze's "Pause/Break". It pauses the current program, and pressing again lets it continue. Try catting a large file, for example :)
It also has some use in some spreadsheets, even MS excel..

Thanks curaga,

What's a sync?  What does it do?  When would I need one?
