You have a new laptop, you install ArchLinux on it and seems like a some things is missing. Certainly this is the case for me, one of this is suspend feature, when doing, my laptop just seems to boot as if I shutdown it, my application is not persisted. Another is a fix for my headphone noise issue, just to name a few.
Some things is missing!
One of the few things you can try is to install the latest beta kernel. In my case it's Linux 4.6. This fix all of the issued I outlined above.
With that said, you need to err on the side of caution, this can make your computer not boot, so please have an CD/Flash drive to boot from in case something is wrong so you can revert back.
All of these process is actually not so bad, so what do you need first.
- Get the package build:
git clone --depth 1 git://git.archlinux.org/svntogit/packages.git linux-packages
makepkg -s- This will take some time, so get you coffee or do something to make use of your time.
pacman -U *.pkg.tar
Reboot your system and voila.
There is also linux-mainline aur to automatically do it for you. However at the time of the writing, it's already on
4.7rc1 and it's really bleeding edge and
4.6 seems to be enough for now.
