In this tutorial, I will attempt to install and use the latest mainline kernel (4.16 when I typed this). I've seen improved performance, responsiveness and battery life in newer kernels compared to the 3.x branch.You can see above that "default" has a value of 1, which indicates to use the 2.6.18-274.3.1.el5 kernel on reboot.Changing this to 0 will cause the first kernel listed to be loaded upon reboot.Lastly, this would make Cent OS a lean, mean and modern beast. The packages, be they the kernel, the headers and the source are identifiable by the meta string . This also means no more intermittent network disconnects under heavy load, as I used to report in pretty much any distro review until about kernel 4.8.7 or so. Just to feel complete, I decided to manually compile the Realtek driver from sources, to see that it's all as it should be. make all make -C /lib/modules/4.16.0-1.el7.elrepo.x86_64/build M=/home/roger/Downloads/rtlwifi_new-master/rtl8723be modules make: *** /lib/modules/4.16.0-1.el7.elrepo.x86_64/build: No such file or directory. Looking under the /llb/modules tree, there is indeed no such kernel, because I've not installed either the headers or the sources just yet. You can do this as before (using the enable flag on the command line), or edit the repo file under /etc/yum.d, and toggle enabled=0 to enabled=1.

The kernel is the main component of your operating system and provides the core functions for your system's applications.So the numbers aren't everything, and the end results are quite promising. The network issues are fully resolved, we can compile again, the performance seems improved despite worse figures in the system monitor, battery life and stability are not impaired in any way, and the Cent OS box has fresh new life, wrapped in modern features and latest software. Once we have that, we can proudly claim to have created the ultimate Linux distro hybrid monster. And none of this was meant to be in the first place, because Cent OS is a server distro. I even install xrestop, which is a small top-like utility to examine the X resource usage, but it did not show anything special. Perhaps I could optimize this, but then, on one hand, the values are higher, on the other, the responsiveness is also better. Here, we have about 2.25 hours with a battery that has deteriorated to about 75% of its chemical capacity, which means, brand new, this battery and this kernel would probably amount to about 3-3.5 hours of juice, with 50% brightness and light desktop load. Now, I can breathe with relief, as I've delivered on my promise, and I gave you a full solution to the Cent OS 7.4 Realtek issues post upgrade.So despite the increase in memory usage and higher CPU activity, kernel 4.16 does not negatively impact the usage at the worst, and it even gives an extra half an hour in the best case. I do not like to end articles on a cliffhanger, and definitely not carry the solution over to a follow-up article, but in this rare case, it was necessary. The kernel installation worked fine, and thereafter, we seem to have gained on many fronts.
