December 18, 2014

Linux Kernel 3.18.1

The first update of the latest Linux Kernel 3.18 series has been released recently. Greg Kroah-Hartman urges all users of this kernel series to upgrade as soon as possible.

Linux Kernel 3.18.1 is a small release which brings some fixes to wireless and alsa drivers. If you’re using the Asus Z99He laptop, a EAPD fixup has been added to solve “internal speaker not working” issue. For details, see the Linux Kernel Mailing List page.

If for some reason, the new kernel does not work properly for you, reboot with the previous Kernel (Grub boot loader -> Advanced -> select previous kernel) and run below command to remove Linux Kernel 3.18.1:

sudo apt-get remove linux-headers-3.18.1-* linux-image-3.18.1-* && sudo update-grub

That’s it. Enjoy!
