The third release of Linux Kernel 3.19 series was released yesterday by Greg Kroah-Hartman. All users of this kernel series were urged to upgrade as soon as possible.
Linux Kernel 3.19.3 comes with many fixes and enhancements for ARM, ARM64, PowerPC, s390, SPARC, and x86 architectures, fixes to the FUSE and NILFS2 file systems, updated drivers for Radeon and Intel graphics cards, sound and networking improvements. See the changelog for details.
How to Upgrade to Kernel 3.19.3:
For Desktop users, first check out your OS type, 32-bit (i386) or 64-bit (amd64), then download and install the packages below in turn:
- linux-headers-3.19.3_xxx_all.deb
- linux-headers-3.19.3-xxx-generic_3.19.3-xxx_i386/amd64.deb
- linux-image-3.19.3-xxx-generic_3.19.3-.xxx_i386/amd64.deb
from the kernel.ubuntu.com.
After installing the kernel, you may run sudo update-grub
command in terminal (Ctrl+Alt+T) to refresh grub boot-loader.
If you need a low latency system (e.g. for recording audio) then download & install below packages instead:
- linux-headers-3.19.3_xxx_all.deb
- linux-headers-3.19.3-xxx-lowlatency_3.19.3-xxx_i386/amd64.deb
- linux-image-3.19.3-lowlatency_3.19.3-xxx_i386/amd64.deb
For Ubuntu Server without graphical UI, you may run below commands one by one to grab packages with wget and install them via apt-get:
