Documentation: *major* cleanup.
Cleanup was long overdue. Old structure was messy and inefficient.

This is also beneficial because development + is now being done on Parabola, where Trisquel is no longer used by the maintainer + at the time of writing. + </p> + + <p> + It details configuration steps that I took after installing the base system, + as a follow up to <a href="encrypted_parabola.html">encrypted_parabola.html</a>. + This guide is likely to become obsolete at a later date (due to the volatile + 'rolling-release' model that Arch/Parabola both use), but attempts will be made to maintain it. + </p> + + <p> + <b> + This guide was valid on 2014-09-21. If you see any changes that should to be made at the present date, please get in touch + with the libreboot project! + </b> + </p> + + <p> + You do not necessarily have to follow this guide word-for-word; <i>parabola</i> is extremely flexible. + The aim here is to provide a common setup that most users will be happy with. While Parabola + can seem daunting at first glance (especially for new GNU/Linux users), with a simple guide it can provide + all of the same usability as Trisquel, without hiding any details from the user. + </p> + + <p> + Paradoxically, as you get more advanced Parabola can actually become <i>easier to use</i> + when you want to setup your machine in a special way compared to what most distributions provide. + You will find over time that other distributions tend to <i>get in your way</i>. + </p> + + <p> + <b> + This guide assumes that you already have Parabola installed. If you have not yet installed Parabola, + then <a href="encrypted_parabola.html">this guide</a> is highly recommended! + </b> + </p> + + <p> + A lot of the steps in this guide will refer to the Arch wiki. Arch is the upstream distribution that Parabola uses. + Most of this guide will also tell you to read wiki articles, other pages, manuals, and so on. In general it tries + to cherry pick the most useful information but nonetheless you are encouraged to learn as much as possible. + <b>It might take you a few days to fully install your system how you like, depending on how much you need to read. Patience is key, + especially for new users</b>. + </p> + + <p> + The Arch wiki will sometimes use bad language, such as calling the whole system Linux, using the term open-source (or closed-source), + and it will sometimes recommend the use of proprietary software. You need to be careful about this when reading anything on the + Arch wiki. + </p> + + <p> + Some of these steps require internet access. I'll go into networking later but for now, I just connected + my machine to a switch and did:<br/> + # <b>systemctl start dhcpcd.service</b><br/> + You can stop it later by running:<br/> + # <b>systemctl stop dhcpcd.service</b><br/> + For most people this should be enough, but if you don't have DHCP on your network then you should setup your network connection first:<br/> + <a href="#network">Setup network connection in Parabola</a> + </p> + +<hr/> + + <h2 id="pacman_configure">Configure pacman</h2> + <p> + pacman (<b>pac</b>kage <b>man</b>ager) is the name of the package management system in Arch, which Parabola + (as a deblobbed parallel effort) also uses. Like with 'apt-get' on debian-based systems like Trisquel, + this can be used to add/remove and update the software on your computer. + </p> + <p> + Based on <a href="https://wiki.parabolagnulinux.org/Installation_Guide#Configure_pacman">https://wiki.parabolagnulinux.org/Installation_Guide#Configure_pacman</a> + and from reading <a href="https://wiki.archlinux.org/index.php/Pacman">https://wiki.archlinux.org/index.php/Pacman</a> (make sure to read and understand this, + it's very important) and + <a href="https://wiki.parabolagnulinux.org/Official_Repositories">https://wiki.parabolagnulinux.org/Official_Repositories</a> + </p> + <p> + <a href="#pagetop">Back to top of page.</a> + </p> + <h3 id="pacman_update">Updating Parabola</h3> + <p> + In the end, I didn't change my configuration for pacman. When you are updating, resync with the latest package names/versions:<br/> + # <b>pacman -Syy</b><br/> + (according to the wiki, -Syy is better than Sy because it refreshes the package list even if it appears to be up to date, + which can be useful when switching to another mirror).<br/> + Then, update the system:<br/> + # <b>pacman -Syu</b> + </p> + <p> + <b> + Before installing packages with 'pacman -S', always update first, using the notes above. + </b> + </p> + <p> + Keep an eye out on the output, or read it in /var/log/pacman.log. Sometimes, pacman will show messages + about maintenance steps that you will need to perform with certain files (typically configurations) + after the update. Also, you should check both the Parabola and Arch home pages to see if they mention any issues. + If a new kernel is installed, you should also update to be able to use it (the currently running kernel will + also be fine). It's generally good enough to update Parabola once every week, or maybe twice. As a + rolling release distribution, it's a good idea never to leave your install too outdated; update regularly. This + is simply because of the way the project works; old packages are deleted from the repositories quickly, once they are updated. + A system that hasn't been updated for quite a while will mean potentially more reading of previous posts through the website, + and more maintenance work. + </p> + <p> + The Arch forum can also be useful, if others have the same issue as you (if you encounter issues, that is). Parabola's + IRC channel (#parabola on freenode) can also help you. + </p> + <p> + Due to this and the volatile nature of Parabola/Arch, you should only update when you have at least a couple hours of spare time + in case of issues that need to be resolved. You should never update, for example, if you need your system for an important event, + like a presentation or sending an email to an important person before an allocated deadline, and so on. + </p> + <p> + Relax - packages are well-tested regularly when new updates are made to the repositories. Separate 'testing' repositories + exist for this exact reason. Despite what many people will tell you, Parabola is fairly stable and trouble-free, + so long as you are aware of how to check for issues, and are willing to spend some time fixing issues in + the rare event that they do occur. + </p> + <p> + <a href="#pagetop">Back to top of page.</a> + </p> + <h3 id="pacman_maintain">Maintaining Parabola</h3> + <p> + Parabola is a very simple distro, in the sense that you are in full control + and everything is made transparent to you. One consequence is + that you also need to know what you are doing, and what you have done before. In general, keeping notes (such as what I have done + with this page) can be very useful as a reference in the future (if you wanted to re-install it or install the distro + on another computer, for example). + </p> + <p> + <a href="#pagetop">Back to top of page.</a> + </p> + <h4 id="pacman_cacheclean">Cleaning the package cache</h4> + <p> + <b> + The following is very important as you continue to use, update and maintain your Parabola system:<br/> + <a href="https://wiki.archlinux.org/index.php/Pacman#Cleaning_the_package_cache">https://wiki.archlinux.org/index.php/Pacman#Cleaning_the_package_cache</a>. + Essentially, this guide talks about a directory that has to be cleaned once in a while, to prevent it from growing too big (it's a cache + of old package information, updated automatically when you do anything in pacman). + </b> + </p> + <p> + To clean out all old packages that are cached:<br/> + # <b>pacman -Sc</b> + </p> + <p> + The wiki cautions that this should be used with care. For example, since older packages are deleted from the repo, + if you encounter issues and want to revert back to an older package then it's useful to have the caches available. + Only do this if you are sure that you won't need it. + </p> + <p> + The wiki also mentions this method for removing everything from the cache, including currently installed packages that are cached:<br/> + # <b>pacman -Scc</b><br/> + This is inadvisable, since it means re-downloading the package again if you wanted to quickly re-install it.

Example filename: libreboot_ukdvorak_vesafb.rom. + </p> + + <h2>parabola won't boot in text-mode</h2> + + <p> + Use one of the ROM images with vesafb in the filename (uses coreboot framebuffer instead of text-mode). + </p> + + <h2>debian-installer (trisquel net install) graphical corruption in text-mode</h2> + <p> + When using the ROM images that use coreboot's "text mode" instead of the coreboot framebuffer, + booting the Trisquel net installer results in graphical corruption because it is trying to switch to a framebuffer which doesn't + exist. Use that kernel parameter on the 'linux' line when booting it:<br/> + <b>vga=normal fb=false</b> + </p> + + <p> + Tested in Trisquel 6 (and 7). This forces debian-installer to start in text-mode, instead of trying to switch to a framebuffer. + </p> + + <p> + If selecting text-mode from a GRUB menu created using the ISOLINUX parser, you can press E on the menu entry to add this. + Or, if you are booting manually (from GRUB terminal) then just add the parameters. + </p> + + <p> + This workaround was found on the page: <a href="https://www.debian.org/releases/stable/i386/ch05s04.html">https://www.debian.org/releases/stable/i386/ch05s04.html</a>. + It should also work for gNewSense, Debian and any other apt-get distro that provides debian-installer (text mode) net install method. + </p> + +<hr/> + + <p> + Copyright © 2014 Francis Rowe <info@gluglug.org.uk><br/> + This document is released under the Creative Commons Attribution-ShareAlike 4.0 International Public License and all future versions. + A copy of the license can be found at <a href="../license.txt">../license.txt</a>. + </p> + + <p> + This document is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
