[gentoo-user] It seems that 'gui-libs/display-manager-init' is not yet unmasked
According to the Gentoo news item[1], I thought from 2nd March, I could use new 'display-manager-init' method. However, it seems yet masked. I don't want to unmask it, and also don't want to accept keywords of 4 packages as news item states. Then, I should wait more, right? Is there any problem or new issue occurred with 'display-manager-init'? [1]:https://www.gentoo.org/support/news-items/2021-01-30-display-manager-init.html -- Regards, W.H.Jeon

That's already there. Options that are available have a number next to them. Press that to jump to the option. Wow!!! O_O I never noticed that. It works too. I did a search for speak and saw a number next to the results and hit it, 1 in my case, and it went right to it. I'm not going to mention how many times I went digging to find something in the past. It embarrassing. ;-) Now that is cool. I just hope I remember to use it the next time. :/ Dale :-) :-) Just watch out and read carefully where you landed on. It could take you to the dependent option, before the specific one. For example, even if you searched 'A' and select the number left-side of 'A', it could land on option 'B' because it must enabled before you can play with 'A'. I surprised twice. First, as you did, when I first noticed I can select with the number, and Secondly, when I noticed it sometimes didn't bring me to the specified option :) -- Regards, W.H.Jeon
[gentoo-user] Is there any Gentoo User webinar? or something like that?
I'm just wondering if there's any. Or are there any past events' video uploaded somewhere? I want to participate or listen to discussions at there. :) And lastly, I'm not a developer and just a Gentoo user, is there also good conference for the regular Gentoo users? -- Regards, W.H.Jeon

I mean, is it quite similarly big to cover most of the normal devices? gentoo-kernel and gentoo-kernel-bin are the same thing underneath; the latter is just a binary distribution of the former. To see the many other packages that do this, run `EIX_LIMIT=0 eix *-bin | less`. I elaborate on this in an earlier message in this thread. Second, how about adding these simple description in the handbook, in the section 'Configuring the Linux kernel'. Then, the new-comers can read and understand the differences and can choose what fits for them. gentoo-kernel isn't under the management of the Gentoo Kernel Team [1]. As the quoted e-mail from M. Pagano (a few messages ago, in this thread) states, it is a non-official project designed to provide as wide coverage as possible. As the purpose of Gentoo is self-compilation and extreme customisability for the gains of speed and size, gentoo-kernel is unlikely to be wanted by those looking for more control and freedom compared to other distros. Why convolute the already-intimidating Handbook with additional choices, when one route (gentoo-sources) will almost-always be preferred ? Although, I agree it should be explained somewhere in the Wiki (or even in the package's descriptions), just not on the Handbook presented to all newcomers.

I don't get it from the description alone. gentoo-sources: A linux kernel source tree with Gentoo patchset gentoo-kernel-bin: A linux kernel binary image with initramfs? gentoo-kernel: ??? This is what Mike Pagano (who maintains gentoo-sources and is part of Gentoo's kernel team) had to say: Gentoo-sources is the upstream kernel with our patches on top. They could include experimental patches (use=experimental), or fixes that have not made it into the mainline upstream kernel. If you have something you might want in gentoo-sources, all it takes is a bug and some discussion and if it makes sense we usually will include it. Gentoo-sources is under the umbrella of the Gentoo Kernel Team. gentoo-kernel is a project done by a developer outside of the kernel team. I believe his goal was to provide a kernel with a sane default config that should generally work for everyone. It looks like it uses the config file from Arch Linux. The kernel project is not involved with that. I think (it's not my work), the idea is like when you install Ubuntu or some other distro where they try to make a kernel with a config covering a ton of stuff so you don't have to compile your own. Unfortunately he didn't say anything about gentoo-kernel-bin. So... no idea. Package gentoo-kernel is the source package. It contains kernel source code + default usable config and builds you a new kernel during emerge. gentoo-kernel-bin contains prebuilt kernel image without any source code. I have two questions. First, how much different between the gentoo-kernel-bin's '.config', and gentoo-kernel's '.config'? I mean, is it quite similarly big to cover most of the normal devices? Second, how about adding these simple description in the handbook, in the section 'Configuring the Linux kernel'.

[gentoo-user] need know-hows to fine-tune the kernel with new hardware
Dear amazing mentors! I bought a new laptop, thinkpad E495. This laptop has Ryzen 3500U and vega gpu. The hardware specification for this particular laptop isn't the topic. I spent bunch of time to start X with this hardware, and then the 'gentoo-kernel-bin' came to my mind. And then it does the work. So, as you can see, this email isn't about 'how can I solve this issue?'. Rather about "Do you have your know-hows to fine-tune the kernel with the new hardware?". I'm doing (a) boot with a quite general kernel, such as sysrescuecd's live iso or Debian, and check '$lspci -k', (b) or turn on a few related options and then turn off one by one until something breaks or doesn't work well. Is there any other good methods to use? -- Regards, WooHyung Jeon
