Gentoo Linux

I used to use the gitlab mirror to browse the ebuilds; I prefer the gitlab UX to the github UX. But, for some reason, it stopped getting updates several months ago. Anyone know what happened?

I want to get more points in speedometer 3 using firefox. I've seen results above 20-24, but I can't get more than 12 because js takes a long time to process. What to do? Rebuild firefox with the -0fast flag?? Or do something with config. I use some fixes in it which just extend limits for everything (almost)

Any suggestions are welcome

So, I have a desktop that has a single-core/2-threads Pentium 4 CPU @ 2.4 GHz and a much newer desktop with an i7 CPU. The older desktop was one that I found on the streets in my neighborhood and that I later fixed and started to play around with it and decided to install Gentoo on it (just because). It's CPU is also so old that it thankfully doesn't have Intel MME. I have also put my older desktop in such a place where I could keep it on for 24/7 (without the risk of it overheating or bothering anyone even when emerging packages).

So, as I was installing Gentoo on it, I figured that I could also use it as an SSH file server and put it behind a VPN (which I could install on my newer i7 desktop (which I could install Debian onto)).

Now, since I wasn't intending to use my Pentium desktop as a file server, I didn't select the hardened profile (and switching profiles would probably take a very long time). So, I was wondering, would this be much of a security concern in my case?

It took about 23 hours to get it booted under its own power using a binary kernel. And on the 4th day (today) I've managed to get a custom kernel working. Gentoo has been very fun to use and to customize, and it's very fast and responsive, even on my old hardware and with a hard disk, browsing heavy webpages with Librewolf is no problem at all. I've been sleeping on Gentoo for WAY to long.

Hello :)

I just finished my first arch install I wanted to set my sights on something more challenging. So, I booted a live image with QEMU Virtmanager to try out gentoo, and after reading the wiki I thought to myself “man i should have started with gentoo”

The arch wiki is good in its own right, but as a beginner i felt really confused and overwhelmed. I felt like I had to google terms just to catch up. The gentoo wiki, however, is really good at explaining concepts and the overview of the technology. When the Arch wiki just says “use mkfs.ext4 /dev/sda2” or something the gentoo wiki actually explains what sda, sdb, etc and ext4 means. I sort of learned it the hard way with arch, but i learn and understand lot more from the gentoo wiki. I love that it explains partition tables, filesystems, heck it even explains what is an IP in the networking section. Making a gentoo system and reading the wiki is basically an interactive computer science course lmao

So, thank you gentoo wiki :)

--autounmask tells emerge to show you what you should add to your package.accept_keywords in order to unmask masked packages.

--autounmask-write tells emerge to automatically modify package.accept_keywords and package.use. You still need to apply the changes using dispatch-conf, since Portage's config files are protected by CONFIG_PROTECT.

{,-write} tells bash to duplicate the argument, adding to the first argument and -write to the second.

What causes the tremendous amount of rebuilds when a new version of ICU is released?

It always seems to be a problem and takes weeks before it seemingly disappears on its own...

While they share a lot of similarities, there are some key differences to consider:

I checked, and both Gentoo and Arch initially released in March 2002, although Arch is older by 20 days.

Hey everyone, I've been using an Arch system for the past 2 months and I've had an absolute ball learning more granular details about my hardware. Never in my life did I think I'd be looking at kernel modules and contemplating swapping out init systems and trying different kernels.

I write this post somewhat open-endesd because I'm clueless as to where Gentoo can take me in terms of hardware acceleration and help me learn development of software/firmware deeper. To my understanding, everything must be compiled from source code, which I'd like to learn more about as well. Ive dipped my toe in a myriad of programming languages too and found a more terminals focused work flow was ideal.

My major use cases for my computer are to benchmark hardware and pick more features in software that I'd have to compile from source anyways. I do work in molecular dynamics from time to time and have used software distributions like GROMACS and LAMMPS. Any advice that could be wouldbbe greatly appreciated. The thoroughness in the Gentoo Wiki's documentation is amazing, but its a overwhelming lol

My foundation is a little like swiss cheese though. Don't know what I don't know! Looking forward to becoming a part of the Gentoo community. I'd love to develop software like DWSIM someday.

Heya Gentoo Crew,

Looking for some moderators to help me out.

It's a pretty chill community, myself being one of the main posters. So should be easy.

Let me know in the comments if you want to help out.

Hi ! I'd like to have a Gentoo computer. But also in the future a Gentoo cell phone. Why not a Gentoo home console?

Is it possible to provide all this hardware with pre-compiled updates with a NAS that would do this automatically periodically?

I have the impression that with Gentoo, I'll be able to create tailor-made systems for my devices, and it gives me lots of ideas, but compiling on all these machines makes me feel a bit cold

Sorry if this is a silly question, I'm neither a developer nor an administrator, but I'd really like to learn how to tinker with my PC !

Recently got a laptop from a friend after mine got smashed to smithereens. I was going to do a fresh install of my favourite binary distro, Void Linux on it but I recently found out they dropped Monero (and Crypto programs) for ideological reasons.

I guess its time to come home!

Booted Laptop/PC to the LiveUSB, time to do my gruelling ZFS installs :)

I haven't gotten an update in about a week which is strange for me. I've had this dependency conflict for a while:

WARNING: One or more updates/rebuilds have been skipped due to a dependency conflict:

dev-python/docutils:0

(dev-python/docutils-0.20.1:0/0::gentoo, ebuild scheduled for merge) USE="" ABI_X86="(64)" PYTHON_TARGETS="python3_11 (-pypy3) - python3_10 (-python3_12)" conflicts with <dev-python/docutils-0.20[python_targets_python3_11(-)] required by (dev-python/sphinx-5.3.0:0/0::gentoo, installed) USE="-doc - latex -test" ABI_X86="(64)" PYTHON_TARGETS="python3_11 (-pypy3) -python3_10"

Would that prevent me from getting updates? I'm able to install things just fine.

Posted something similar on the NixOS sublemmy, but it basically boils down to the fact that I tend to switch back and forth between both distros, and I enjoy both very much as both Gentoo and NixOS provide an immense degree of control over my system and allow me to go wild and do whatever I want. But I feel the need to settle on one system and tinker with the other on a VM instead, as this switching back and forth is becoming a time sink and hindering my studies somewhat. The question is, which to use as the main desktop system? Gentoo feels more intuitive to me, but NixOS is definitely powerful at managing complex systems, but then again, I only have a simple desktop system. Another thing that I thought of is that maybe I can somewhat replicate NixOS' rollback feature, which is my absolute favourite feature of it, using a combination of Git and ZFS snapshots? I'd like to hear your thoughts on this.

I've heard that you should be using the appropriate stage3 archive for the profile you want to use, but what exactly are the differences between them? I'm asking this because I want to try doing a Hardened/SELinux/Musl/LLVM install, and there's a profile for that, but not the stage3 archive. I was thinking of starting with either Hardened/Musl or LLVM/Musl. Any thoughts on that?

Was able to install gentoo on a Oracle always-free instance. It has 4x ARM CPUs and 24 GB RAM. Those specs are really nice for a free instance.

for now I'll use it to self host some public facing services. Who knows, maybe I'll host a personal lemmy instance on it :)

Typically, this is handled by DHCP server, but if you have enabled EnableNetworkConfiguration in the iwd config, then iwd is the one deciding which is your DNS server, and relays that information to your resolver, which in most cases is systemd-resolved but sometimes openresolv.

This is also the same as setting the standalone USE flag

Personally for me, I've always been a fan of bspwm

I've been using hyprland as of recent to try it out. But I think I'll be trying something else soon. But I do want to stick with wayland.

I tried wayland with Hyprland on gentoo with proprietary nvidia drivers. I have the RTX 3060 Ti card. It works out of the box without having to mess with anything.

I tried sway as well. I have to specify the --unsupported-gpu flag for it to launch. The one issue I noticed with sway is that the background does not seem to load. I did not spend time debugging so it maybe a super simple fix. I'll report back if I ever do.

But I'm happy to see its all working flawlessly!

What can I do, as an end user, when a testing package on the gentoo tree has been outdated for a while? I know I can just download the tar file of the source code and compile it myself, but I wonder if there is anything else I can do to help on the gentoo repos.

For example Waybar has a 0.9.18 version available upstream, but not on gentoo. This version was released about a month ago, and includes compatibility for dwl. It's not really an issue for me, since I compiled the 0.9.18 version manually, but I'd like to know if there is anything I can do to help.

Sorry if I'm not using all the correct terminology; I'm new to gentoo.
