installing debian on an: Apple PowerBook G4 550 (Gigabit - Ti)

[sergio sevillano <sergiosevillano.mail@gmail.com>]

i have tried many live cd distros un-successfuly

i gess im having trouble with the graphic card:
(ATI Mobility Radeon (4X AGP) graphics with 16 MB of DDR SDRAM;  screen 
size is 1152x768 )
so all previous installations where ok but after final reboot
i could not visualize the desktop.

finally i have installed debian502 but with no desktop.
plain console that looks ok to me.

can someone give me a hint of what should be next step?

i gess is finding a driver for the card,
then installing KDE?

thanks
