uname -rĤ.19.0-20-amd64 Step 2 - Update the Sources Let us confirm the current kernel version we're on using the uname command. This can be upgraded to 5.x version available right now using the backport repository. Step 1 - Find Current Kernel Versionĭebian 10 comes with Kernel 4.19 as default version. Kernel acts as a bridge between applications and data processing performed at hardware level using inter-process communication and system calls. It is core component of an operating system. It basically manages operations of memory and CPU time. Kernel is central component of an operating system that manages operations of computer and hardware. As I always say, the choice is ours.Installing the Linux kernel 5.x on Debian 10 Zen and RT should also be taken into account by gamers and content creators respectively. In the end, it's best what best suits our needs, and if there are so many options, it is because they are necessary. If we want the latter, and our distribution doesn't use it, the stable Linux kernel should be the second thing to consider. It may not use the latest stable version, but it should include the latest security patches. Which Linux kernel should I use?įrom my point of view, what our distribution offers it is close to being the best alternative for us. It is recommended by the Free Software Foundation. Linux-libre is a project that maintains several modified versions of the Linux kernel that are remove everything that does not include source code and other software that uses proprietary licenses. There are distributions, such as Garuda Linux, that use this kernel to improve performance, something to keep in mind if you use a laptop and it can't take a long time without loading. In general, it has modifications so that it works better in daily use on a desktop system, as long as we take into account that it can reduce autonomy, something that it can also do in the opposite direction. For this reason it is considered by many as the best option for gaming. It's a Linux kernel designed with performance in mind, but it also consumes more power when you're pulling all the stops. Keep in mind that the extra layer of security could cause some programs to not work with this kernel, so it should only be used if security is the most important thing for our use and equipment. It is a "hardened" version of the stable Linux kernel, more security-focused, and comes with patches that the stable version has not yet received. These kinds of problems are minimized with a -rt kernel or in real time. For example, if we connect an electric guitar to a computer, put on headphones and the software is not in good condition, we could end up hearing the sound with some delay, making it practically impossible for us to play well. When we work with audiovisual content, there may be a delay between a signal and when it reaches the equipment. Therefore, they are more stable than the stable ones, forgive the redundancy, but they do not receive news that is not to fix something. The nice thing about an LTS kernel is that does not receive new functions that they could break compatibilities, that and that they receive many corrective updates. Usually they are supported for five years, but the maintainers can decide that this time is reduced to 3 years. Support time depends on the maintainers, and, for example, Linux 5.15 LTS is supposed and expected to be supported for less time than Linux 5.10 LTS. LTS stands for Long Term Support, which means that it is supported for a longer time. It is what is used in most distributions, as long as they do not opt for one like the next one on the list. is thrown a new update every two months or so, and the first issue is uploaded once every three years, more or less. As its name indicates, it is the stable version of the Linux kernel, and it is the one developed by Linus Torvalds together with his collaborators.
