Hi,
A new KDE Neon release was launched on 4th July, also with a new kernel. Now is 4.18, instead of 4.15 series.
I am on the 4.15 series kernel and I wish whether is possible to receive the 4.18 kernel or, maybe, we have to install the kernel from synaptic or apt.

Regards

You will need to enable Ubuntu's Hardware Enablement Stack (HWE).
If Neon hasn't modified how Ubuntu does this, it is not enabled on the first 'point' releases of the 18.04 ISO (18.04 and 18.04.1), but is enabled by default in the newer images. So, if your setup is a bit older, you do not automatically get this. I saw discussion somewhere on whether or not Neon were going to enable this for all installs, but I can't find it, and I don't think that I saw any decision on it. Luckily it is an easy thing to do.

I do not use HWE stack, cause it includes xserver-xorg-hwe-18.04 which comes with outdated-ish drivers, imo.
I just installed linux-headers-4.18.0-* packages directly alongside Padoka's PPA for video drivers. Hurray to smooth gaming.
With that setup, you should end up with the latest 4.15.* kernel and two latest 4.18.* kernels installed, where the newest kernel (4.18) will be the default that the OS will run on. At least that's how it became with my setup. Though to be honest I was just mostly stumbling around.

The HWE xorg stuff is fine as a starting place, and the PPA does not update xorg itself (though currently the changes via HWE are minor there), which can be updated using Padoka, et al if one has an AMD or Nvidia graphics. Intel folks may not see much, if any improvements using Padoka, vs the updated HWE intel driver, as the PPA does not update
xserver-xorg-video-intel, but of course does update Mesa.


But as usual, there are many ways to get what you want

I actually had to explicitly stop using HWE stack. Previously I had HWE for xorg stuff and the PPA for the mesa stuff, but roughly a month ago that appeared to be insufficient for whatever reasons. Specifically, i was having graphical issues where SDDM and Plasma kept on flickering when animating things (such as the fade-in animation after you login through SDDM). Occasionally taskbar and notifications would also flicker for whatever reason. Before that however, I did not have any problems at all for months.

When trying to install the driver from the PPA, it wanted me to remove all HWE xorg related stuff as well. So I did that, found out and installed newer non-HWE linux-image's packages, then no longer had the issues ever since.

Though till date, I still don't know what the specific causes were for the issues that I had. I just assumed the HWE xorg stuff were outdated-ish. Though I also assumed I was only having the issues due to also using the PPA's mesa stuff.

I had no conflicts when I added padoka, as of last week. This sort of issue is likely from the PPA maintainer needing to adjust the packaging configs to prevent conflicts. Most *buntu 18.04 based distros installed from 18.04.2 and newer isos come with HWE kernels and drivers by default, so I would imagine a huge number of folks would notice this sort of snafu

I actually thought so as well, so I remained suffering with the issues for a few weeks while occasionally googling around and searching this forum every few days, looking for other people that had the same issue as me,.. but I couldn't find any, lmao.
Eventually I couldn't stand it any more and stumbled upon that solution.

Perhaps it was unique to my system, I probably won't ever find out.

Anyway, I just thought of mentioning that just in case someone else had the same issue as me when using both HWE and Padoka's PPA.

Hi,
I did what claydoh wrote and it works.
I am going to reboot and clean the garbage.
