Obecné otázky týkající se Sabayon Linuxu
Proč si vybrat právě Sabayon Linux ?
Sabayon má více vydání, ze kterých si můžete vybrat. Od vydání pro různé počítače, po vydání kolekcí balíčků. Od vydání, která mohou být zajímavá pro nové linuxové uživatele po vydání pro pokročilé uživatele, kteří preferují větší přizpůsobivost.
2) Sabayon je rolling release.
To, co jednou nainstalujete, již není nutné znovu přeinstalovávat kvůli tomu, že vyšla nová verze. Aktualizace programů probíhá pomocí nástrojů na ploše. Ty vám umožní, abyste vždy měli poslední vydání vašich programů.
3) Instalátor Anaconda.
Instalátor Anaconda v Sabayonu zjednodušuje instalaci zahrnující také rozdělení disků a šifrování disků.
4) Volba správce balíčků a repozitářů.
Správce balíčků Sabayonu - Entropy je binární a nyní obsahuje kolem 10,000 balíčků. Správce balíčků Gentoo - Portage je založený na zdrojových kódech a je "trochu" větší.
V Sabayonu je spousta možností, kde získat podporu. Můžete procháze fóra, live nápovědy a rostoucí wiki.
Sabayon je obecně považován za 1 z nejvíce oku lahodících linuxových distribucí. From the installer, to the desktops, and down to even the terminal which has a color scheme applied to make any work on the command line pleasing to the eye and easy to understand. 7. Using Sabayon helps to save the world Test results have shown using Sabayon Linux improves the economy; helps reduce global warming; is generally good for the environment; promotes world peace; and helps to fight off alien invasive species from other galaxies. It is also shown to be helpful in improving the health of you sense of humor, which is important to keep from bashing your head on the key board during difficult moments. (Test results may vary as number 7 is considered an attempt at humor)
What is Sabayon Linux based on?
Sabayon Linux is based on, and emanates substantially from, Gentoo GNU/Linux(Gentoo testing). Gentoo Linux is one of the most popular source-based Linux distributions. As Ubuntu uses some of the packages from Debian, so Sabayon recieves its packages from Gentoo. In particular, Sabayon is based on Gentoo's testing branch. Gentoo's testing branch is about on par with Debian's Sid (unstable branch) releases. Though based on the bleeding edge, you will find Sabayon is quite stable and perhaps more cutting edge. Both Sabayon and Gentoo are on rolling release cycle, but Sabayon will have release snapshots.
Sabayon when using the package manager Entropy is binary based. (currently Sabayon has about 10,000 packages in Entropy)
Sabayon when using the package manager Portage is source based. (the Gentoo repo is quite huge)
What is difference between source-based and binary based distribution?
Most distros, such as Ubuntu, Debian, Red Hat, Fedora and SUSE, install binary packages. Simply put, a binary package is the pre-compiled program, compiled on another computer and made available for download and installation on other computers.
A source-based distro is a distro that compiles its programs from source code on the target computer at the time of installation, rather than relying on others to compile and package them. Source-based distros generally also have in their repositories some binary (pre-compiled) packages; these will be the large programs such as OpenOffice, the reason being that the compilation of these can take several hours.
Should I use Sabayon as a source-based or binary based distribution?
Sabayon Linux has two package managers: Entropy (binary packages) and Portage (source packages). As you can install binary packages instead of source code-based packages, Sabayon Linux offers users a choice and the best of both worlds. The binary packages in the Entropy repository have been built by using the Portage package manager and then packaged using Entropy packaging tools on that computer. The binary packages are stored in the Entropy repository and you install them on your computer by using either the Equo command line client or the Sulfur GUI client. As the release time and date of packages are a little different between the 2 package managers it is recommended to use one package manager consistantly to avoid conflicts.
Generally, using Entropy with binary packages is recommended to new users and those who just want everything to work easily.
Portage(source based is recommended for more advanced users who wish to customize thier installation to a higher degree.
There are two main advantages to source-based distributions. Firstly, source-based distros often have the newest software before binary distros do. This is due mostly to the fact that, rather than having to compile a package and then test it on different machines, all that is required in something like Sabayon Linux is a file telling it where to find the source code and how to compile it. Secondly, undoubtedly a program will eventually have a feature you don't need, and will just take up space or slow down the program. In a binary distro, you're stuck with this feature. In a source-based distro you have the option of removing unwanted features at the time of compilation (assuming you are using Portage rather than Entropy).
What Editions are available in Sabayon Linux ?
Sabayon is all about choice. You have many flavors to choose from.
The following choices are the main releases available in 32bit(x86) or 64bit(amd64):
KDE is a full feature release.
Gnome is a full feature release
As of January 2011 these are still somewhat experimental (use with care):
3. LXDE 4. XFCE 5. Enlightment 6. ServerBase 7. SpinBase
CoreCDX is a minimal install for those wishing to configure the system more to their liking (for more advanced users) in 32bit or 64bit:
We also have a current Gaming Edition but this available in only 32bit(x86)
How do I get the Desktop Cube thing working?
The desktop cube and 3D graphics do not work after I installed Sabayon Linux to the hard disk, but do work when I'm using the LiveCD/DVD.
Well, in theory what you see when you run the LiveCD/DVD is what you get when you install Sabayon Linux. So if the 3D desktop was working with the LiveCD/DVD then it should work when you boot your new installation. Well, we know all about theories; it doesn't work for everyone. You can either search in the Sabayon Linux Forums and the Sabayon Wiki for help on how to get the 3D desktop working with your particular model of graphics card, or you can ask in IRC #sabayon.
First thing you need to do: make sure the md5sum is good after you downloaded the .iso file, I can't stress that enough. Make sure you have burnt the CD/DVD as slowly as possible, and enable Burn Verify in your burning application.
You will be asked those two questions every time, so please do this so we don't have to waste bandwidth re-asking. It may seem petty to you to check the md5sum but, without knowing you're starting out with a good ISO file, it's pointless to continue. We can spend weeks troubleshooting and if your md5sum was bad, we just waste a lot of time and it causes a lot of frustration. With a bad md5sum you can still get a bootable working desktop, but may have issues elsewhere. So keep in mind, just because it boots, doesn't mean the ISO file is good. How do I check the md5sum and disk you ask? Well, luckily for you: HOWTO: Checking the integrity of a LiveCD or LiveDVD.
OK, so you made sure the md5sum was good and you burnt the disk at a nice slow speed with Burn Verify enabled. Now we can start looking at other things. Do you have the correct video driver and the latest version of it? That will be the first thing to know.
NVIDIA card owners, the following link will save you hours of frustration. Yes, certain cards require certain drivers: http://en.gentoo-wiki.com/wiki/Nvidia. If you do not know or understand what is 'masking' then please read more (Portage users, see http://dev.gentoo.org/~dang/masked.txt. Entropy users, see Entropy#Masking_and_Unmasking_Packages_in_Entropy.
Our Wiki also has a HowTo get NVIDIA and ATI cards working too, so use the relevant information: HOWTO: Get Ati or Nvidia Video Cards working in Sabayon. Also search the Sabayon Linux Forums for posts mentioning your card manufacturer and model.
The above method will work for most people, but you will find that maybe it didn't work for you. Why? I don't know. A little bit of research into /etc/X11/xorg.conf can usually resolve the remaining few that have problems. The following link is full of information for AIGLX: http://en.gentoo-wiki.com/wiki/AIGLX/Troubleshooting. Again, only use the information that is relevant. You will want to pay attention to the xorg.conf settings shown on that page and compare it to your xorg.conf so it matches.
Still having problems? Buy a new video card!
If you want to post your special way of how you got it working - please do. Mine just works all the time so I don't have such problems.
