Today I tried booting Lubuntu on my G5. First up was the PowerPC Desktop version 16.04, next was the current version 16.10, finally version 16.04.1 of Ubuntu Mate. All three (3) versions enter the GUI and at some point after that the DVD stops and the screen image becomes distorted, image here. Since all three (3) installs exhibit the same problem and it's not listed on the PPC Known Issues - I suspect hardware. Video card perhaps? Currently a NVIDIA GeForce 6800 Ultra. Background: This week my favorite IT channel switched streaming providers and now requires H.264. None of the PPC browsers or video players for the PPC can play the H.264 stream . So it's time to either leave Leopard (by switching to Linux) or replace the G5 with a RaspberryPi.
