Bueno, la impresora funciona sin ningún problema en el Karmic Koala.

El escaner hay que proceder del siguiente modo:

sudo aptitude install sane sane-utilsii

Descargar iscan desde aquí.

sudo perl -p -i.bak -e 's/scsi EPSON\n/#scsi EPSON\n/g' /etc/sane.d/epkowa.conf

Dibujar un eje de coordenadas en LaTeX usando pstricks.

   Muchas veces al realizar un documento científico resulta útil dibujar una función. Para ello conviene empezar por conocer cómo se pinta un eje de coordenadas.

   Una opción sencilla para pintar tanto ejes de coordenadas como funciones, diagramas, grafos, ... es utilizando pstricks. 
   Para emplear pstricks es conveniente añadir los siguientes paquetes al documento:

\usepackage{pstricks}
\usepackage{pst-node}
\usepackage{pst-plot}

  A partir de ahora ya se puede empezar a insertar gráficos usando pstricks. La forma más sencilla de dibujar un eje es mediante la sentencia \psaxes. Un ejemplo muy sencillo es el siguiente:

\begin{pspicture}(0,0)(4,3)
 \psaxes{->}(4,3)
\end{pspicture}

La forma de la macro es la siguiente:

\psaxes*[par]{arrows}(x0,y0)(x1,y1)(x2,y2)

Las coordenadas son cartesianas. Los puntos (x1,y1)(x2,y2) son la esquina inferior y la esquina superior respectivamente. El punto (x0,y0) indica donde se intersecta el eje x con el eje y.

\psaxes[linewidth=1.2pt,labels=none, ticks=none]{<->}(2,1)(0,0)(4,3)

Si se omite el punto (x0,y0) entonces el origen es el punto (x1,y1). Si se omiten (x0,y0) y (x1,y1) entonces el punto de corte es el (0,0).


Los parámetros que pueden ir dentro del corchete son los siguientes:

• labels=all/x/y/none   Por defecto: all
     Especifica si las etiquetas de los ejes aparecen en ambos ejes, sólo en el eje x, sólo en el eje y o ninguna etiqueta respectivamente.
  
• showorigin=true/false  Por defecto: true
     Si true, las etiquetas se ponen las etiquetas del origen. Si es falso no se ponen etiquetas en el origen.
  
• fdsfsa

Error: El sonido no funciona en karmic koala tras la actualización.

El sonido no funciona en karmic koala tras la actualización.
No tengo muchas ganas de explicar lo que hace cada sentencia, así que directamente pondré los comandos que hay que meter en la consola uno tras otro:

sudo apt-get install grub2 linux-backports-modules-alsa-karmic-generic

sudo add-apt-repository ppa:ubuntu-audio-dev/ppa

sudo apt-get update

sudo apt-get dist-upgrade

mkdir ~/pulse-backup && cp -r ~/.pulse ~/.asound* /etc/asound.conf

(Sigue la línea) /etc/pulse -t ~/pulse-backup/
 

rm -r ~/.pulse ~/.asound* 
 

sudo rm /etc/asound.conf 

sudo apt-get install libasound2-plugins padevchooser 

(Sigue la línea) libsdl1.2debian-pulseaudio

sudo apt-get remove --purge libflashsupport 

(Sigue la línea)flashplugin-nonfree-extrasound

pulseaudio & pavucontrol 

Si quieres echarle un vistazo al volumen:

alsamixer -Dhw

Eso es todo. Ánimo!!
