Since I am tired to constantly recite this list whenever one of these designer-type people tells me that they need Adobe’s Whatever Suite to do some basic task here is a summary that I can point them to.

Vector Graphics

Inkscape (http://inkscape.org/)
Xara Extreme (http://www.xaraxtreme.org/)

Raster Graphics

Gimp (http://www.gimp.org/)

Desktop Publishing

Scribus (http://www.scribus.net/)

Photo Editing

Gimp (see above)
Darktable (http://www.darktable.org/)
RawTherapee (http://www.rawtherapee.com/)
Luminance HDR (http://qtpfsgui.sourceforge.net/)
Layout Tools (DTP): Scribus (http://scribus.net/canvas/Scribus)

Since the latest version of GIMP has not been included in the main 12.04 repositories because it was not ready at release time you have to use a PPA at current.

sudo add-apt-repository ppa:otto-kesselgulasch/gimp<br></br>sudo apt-get update<br></br>sudo apt-get install gimp

TIP: Go to the “Windows” menu and select ‘Single-Window Mode’ to use Gimp in one window (see screenshot).
