Netbook Kernel question
« on: 22. February 2015, 12:53:37 »
Hi,
I am running Manjaro Netbook edition on my old Samsung NC10. It comes with kernel 3.14 and another 3.14 kernel that is labeled as a Netbook kernel in grub. My questions are:

How does the netbook kernel differ from the normal kernel (I just know it is optimized for Intel atom)?

When I install a newer kernel through mhwd-kernel it is not listed as a netbook kernel at boot.
Is it a netbook kernel anyway?
If not, is there a way to get a newer netbook kernel?
If not, should I use a newer kernel, or the older netbook kernel?



Ps. Thx for any help ahead of time. I think about this kernel thingy on my netbook all the time and I could not find any detailed documentation regarding it.


greetings
Lennart

Hi,
I am running Manjaro Netbook edition on my old Samsung NC10. It comes with kernel 3.14 and another 3.14 kernel that is labeled as a Netbook kernel in grub. My questions are:

How does the netbook kernel differ from the normal kernel (I just know it is optimized for Intel atom)?
It's also uses a little less memory due to having infrastructure/drivers for some hardware that definitely would never be coupled with Atom CPU removed. Some settings are tweaked that may, on some newer netbook hardware, improve battery life a little.

You can view the kernel config file here:
https://github.com/manjaro/packages-community/blob/master/linux-netbook-manjaro/config

and compare to the normal 3.14 kernel's config here:
https://github.com/manjaro/packages-core/blob/master/linux314/config

If I install a newer kernel through mhwd-kernel it is not listed as a netbook kernel at boot.
The netbook kernel doesn't integrate with mhwd.

Is it a netbook kernel anyway?
No.
You can view information about the current kernel you're running by issuing uname -a in a terminal. If the output text doesn't have the word 'netbook' amongst it, it's not the netbook kernel.

If not, is there a way to get a newer netbook kernel?
If you mean within the 3.14 LTS series, you'll get one soon, it's overdue for an update.

If you mean a kernel of newer series than 3.14; i wasn't planning to move to a new series any time soon. Eventually it will happen.
If you can demonstrate a newer series of kernel having real advantages for common netbook hardware now, i'd be interested to hear about it.

If not, should I use a newer kernel, or the older netbook kernel?
I suggest using the netbook kernel if you have an Atom-based netbook, but ultimately it's up to you.

I thought it replaced Plasma 4 and not KWin? Because the starting instructions require you kill plasma-desktop, kuiserver, and krunner, but kwin remains running.???

Seems you have the wrong thread. :P
