It’s best to have the latest one so you know you won’t come across that issue.Last but not least, many major updates to the kernel improve the overall speed of the system.Occasionally, major updates to the kernel in Linux also brings some new functions.These functions are basically parts of the kernel that programs can use to do some sort of task or operation.Out of all the drivers being updated, the graphics drivers are probably those that you’ll notice the most, as every refresh usually adds a bit more performance.While it’s always possible to go the proprietary route, knowing that the open source drivers keep getting better and better is good too.
See “Processor Speculative Execution – Operating System Updates” for more information.
While some changes can be very subtle, others aren’t and can make a big difference, such as the famed 200-line patch that increased the overall productivity of a Linux machine by quite a bit.
There are even some crazier changes such as this, where Linux can run off of zero CPU cores.
For consumer-type users, the benefits that come along with it far outweigh the risks.
Additionally, each kernel that you update to will have been tested for at least a couple of days by developers and test users to ensure that it runs without a hitch.While those were the updates you get with minor kernel updates (say 3.2.0 to 3.2.1), let’s check out some improvements you can commonly see with major updates (think 3.2 to 3.3).
