Question: My Ubuntu 11.10 desktop has an option to suspend when inactive (under System Settings > Power) but no option to hibernate. How can I hibernate it after a period of inactivity?

Answer: 
Corel as well as Illustrator can recognize and read SVG format. But the problem is that sometimes they don't open SVG properly.
Generally some publishers can print from pdf. I think, the main issue is to get along with the publishing house about the file prepared for print.
You can Use [Inkscape](http://inkscape.org/) you can import the ilustrator 9.0 version file, and corel 7 X14 version files but i don't recommend to you those formats because the conversion is not so good.
Normally wen i have to deal with files from others programs, i use PDF or SVG the standart file of Inkscape.

I hope i have helped.
