The kernel can be seen as the engine of the Linux OS - it contains nearly all of the drivers for your hardware. KXStudio 12.04.3 runs the 3.8.0-32-lowlatency kernel by default. This kernel will be fine for most people but, most significantly for users of an audio-centric distro, you may not be able to run JACK with optimal settings if you are using USB audio devices such as the Focusrite Scarlett family of USB devices, for example. | The kernel can be seen as the engine of the Linux OS - it contains nearly all of the drivers for your hardware.

- | Intel graphics users need not worry about installing the 3.11 kernel but at the time of writing I was unable to install the non-free Nvidia drivers from the Ubuntu repos for 3.11 and have them work so I was stuck with the considerably less complete and performant Nouveau xorg graphics drivers. I cannot comment on the AMD/ | + | |
+ | Intel graphics users need not worry about installing the 3.11 kernel but at the time of writing the Nvidia drivers available in the Ubuntu Precise repos do not support kernel 3.11. This may also be the case for some ATi/AMD Catalyst users. Nvidia 3.11 users must use at least driver version 331.20+ so it is recommended that Nvidia and ATi users who want to fully utilise their hardware wait for newer, 3.11 compatible graphics drivers to make it into the Ubuntu repositories before upgrading. The updated drivers can be expected to be available from the repos by March 2014. | ||
