I just installed Leopard on my iBook G4 (1.33/768MB) and neither Gimp nor Gimpshop work anymore. I installed X11 from the install DVD but that didn't do anything. When I try and open either one of them up, an x-term window pops up, the app says it's "caching fonts" for a while, then it unexpectedly quits, while X11 sits open. Any suggestions?
