Ubuntu

Is a popular Linux distribution, best suited for desktop computers. It is based on Debian, therefore the packaging (*.deb) works rather well.

This page (so far is by no means an installation guide) but it contains some extra information.


Displays

Most Linux distribution's installer (at least the free ones) can't handle some slightly more fancy hardware automatically

Usually you have to do two things

  1. Find and install a driver for your graphics card
  2. Hand edit the /etc/X11/xorg.conf file.

Example Nvidia FX + 2 digital monitors

I have a Quadro FX 3450 card, a 24 and a 20 monitors. This is an executive summary. Find better explanation on Google :)

(1) You need to download the Nvidia driver. http://www.nvidia.com/object/unix.html E.g. file NVIDIA-Linux-x86-1.0-9755-pkg1.run

(2) Save the xorg.conf file 

cp /etc/X11/xorg.conf /etc/X11/xorg.conf.save1

(3) Install the driver 

sh NVIDIA-Linux-x86-1.0-9755-pkg1.run

(4) Run the X server configurator (but make sure you have a copy of your old xorg.conf file !!) 

nvidia-xconfig

(5) The result won't do it, but it's a start. You have to hand-edit and merge information from the old xorg.conf.save1 file !!!

E.g. I have this (I am minimalist and hate configuration work, so I stop when it works). I.e. if you want a single display for both monitors (you can drag stuff from monitor to the other) you only need to define one screen. Below may some not used or even slightly harmful stuff ...

Printers

Printers don't necessarily work automatically either:

A good bet is to use this application:

Before you do so, it is like that you need a a PPD file (a file that defines properties of your postscript printer). Get it from:

Example Infotec

Example for Infotec ISC 1032 (A low end color copy and printer machine)
