Gimp and inkscape for vector work, both nice. There is also PhotoGimp, kind of an overlay that changes the interface of Gimp to resemble Photoshop, nice for those transitioning. There is also Krita which has been getting a lot of development, cross between Photoshop and Illustrator, reminds me of the old Adobe Fireworks program. Who remembers that old line of software?
Yeah, give DODI repacks a try and see if they work for you.
