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.

On an older Pentium Intel Nuc, only OpenSuse can wake it up from sleep, why? (lemmy.world)

Linux Noob here

The Nuc is sitting under my TV and my wife uses it mostly to watch reality tv shows, cooking shows, etc on different websites. The requirement was for the Nuc to go to sleep after 30minutes of inactivity and to wake it up with the keyboard.

It had Leap 15.3 so I wanted to upgrade it but I managed to botch the upgrade. I decided to go with Debian instead, installed it, configured everything and when I handed it over to my wife I realized the Nuc never woke from sleep. Then I remember I had this problem in the past with it when I tried a whole bunch of distros and none of them managed to wake it up. I also read on Intel forums where people complained about the same issue with different Nucs and I think the general consensus was that it's a problem with the Nucs and it can't be solved.

What happens is, when the Nuc is sleeping, the power LED slowly blinks. When you wake it up, the LED goes completely away, like it's turned off but you can hear the fan is starting to spin. However, you don't have any image and you have to hold the power button a lot longer to turn if off, like it soft-resets.

So I nuked Debian, installed Leap 15.5 and it wakes from sleep without any issues. I am happy that it does and I like Opensuse but I have no idea what it does different compared to other distros in this regard.

OK, so this is one of those comments that's either "wtf, of course everyone knows that" or "oh shit, ok", but generally wake on USB is a bios setting. Have you looked around in the bios to see what your options are?

Doesn't explain the weird behaviour, but may be a good way forward.

Actually It's a good point, yes it was enabled. It worked a few hours before on Leap 15.3. So far it works only on Opensuse, that's why I wondered why.
