From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

For those running Linux with Window Managers (or Desktop Environments too), how do you make sure that on lid close: the laptop suspends and locks? (lemmy.world)

Linux is cool, I can do a lot of things with it. If i set a config file in Linux, I am damn sure that it is ran every single time. The code does what you tell it to do.

There is 1 thing that always seems to be "black magic": 1) lid close and suspend 2) lid close and suspend and lock.

If we ignore locking for a moment and focus on suspend. I cant seem to figure out why sometimes lid close would suspend immediately, when other time it takes 5 seconds after lid closes. On some days, lid closes would not even suspend !!

Did anyone manage to get suspend work 100 %? I cant believe we have tons of great linux tools and years into kernel dev, and still suspend is a hit or miss.

Have a look on the Arch Linux wiki around udev and event debugging (evdev?)

Depending on whether you're suspending to RAM or disk will affect the time it takes - and of course, how much stuff it has to suspend.

If you're in the middle of a resource intensive task (which could just be watching a video... all depends...), then whatever is running needs to stop, and possibly has a full buffer which needs processing as suspend could be to the swap file / partition, which may need emptying first.

But, it should all work these days.
