I am talking about the OP's first few words of him not being able to get a 32bit version of Hardy Heron working.
Am I a Linux expert? . . . . . . not in this lifetime, but I have suggested the gigabyte 690G-S2H board to 15 people that wanted to try out Linux on the side, and no one has had a problem with the graphics - only sound over HDMI.
So I am asking about he OS itself - why not install the 64-bit OS that was meant for 64-bit machines? If the OP is using an older 32-bit processor on an AM2 board (which I thought AMD had done away with a long time ago . . . . . did they even make 32-bit processors that could be used in an AM2 board?), then I understand the using of a 32-bit OS. For all I know, it may not have nothing to do with the graphics, but with the kernel itself.
Is the graphics working before you install the proprietary drivers?
. . . this is the digital projection of your mental self. . . .
