Debian 8.3.0 on Powerbook G4
Hello all! I'm new to Linux, and I just installed Debian 8.3.0 on my Powerbook G4 550 Titanium (512K memory). Everything went smoothly, although it took a few hours. I installed from a DVD, without an internet connection.
I chose GNOME, LXDE, and CINNAMON from the UI list.
After install, my DVD was ejected, and I restarted. Its fine until it gets to the desktop, which is black, with a large (screen-wide) white splotch, that moves from the top of the screen to the bottom, then fades to black.
I can't see cursor, or anything at this point. Did I miss something?
thanks for your time.
