See the announcement.
Install / Upgrade to Kernel 3.12.10:
The Ubuntu Kernel Team has build the deb packages which are available in this page. Low-latency Kernel packages are also included.
If you’re comfortable with command line, you can also follow the steps below to download & install this kernel:
1. Download Kernel DEBs:
For 32-bit system:
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12.10-trusty/linux-headers-3.12.10-031210-generic_3.12.10-031210.201402061553_i386.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12.10-trusty/linux-headers-3.12.10-031210_3.12.10-031210.201402061553_all.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12.10-trusty/linux-image-3.12.10-031210-generic_3.12.10-031210.201402061553_i386.deb
For 64 bit system:
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12.10-trusty/linux-headers-3.12.10-031210-generic_3.12.10-031210.201402061553_amd64.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12.10-trusty/linux-headers-3.12.10-031210_3.12.10-031210.201402061553_all.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12.10-trusty/linux-image-3.12.10-031210-generic_3.12.10-031210.201402061553_amd64.deb
2. Install all the packages:
sudo dpkg -i linux-headers-3.12.10-*.deb linux-image-3.12.10-*.deb
Once installed, restart your computer and done.
If you’re using a proprietary video driver, you may need to re-build or re-install to get it work with the new kernel.
If for some reason this kernel release doesn’t work properly for you, reboot into previous kernel (Grub -> Advanced -> select previous kernel) and run this command to remove Linux Kernel 3.12.10:
sudo apt-get remove linux-headers-3.12.10-* linux-image-3.12.10-*
