after some trail and error, I finally managed to install 15.10 on my rebuilt iBook G4 (1.07 Ghz, 1.2 GB Ram, 16GB SSD, 32MB ATI 9200 gfx)
unfortunately, it seems to crash like 90% of the time. when moving around a window, it crashes like 99% of the time.
crash means, the screen goes dark, flashes to show desktop again and after 1-2 seconds, it gets dark again (and this behavior repeats forever)
oh - and sometimes, it´s even worse - it hangs on the desktop screen, only the mouse.cursor reacts and that´s about it! the ubuntu logo from login-screen is blended into the desktop background image (also with that logo, but in a different place) - so I get double logo
next thing is, when open the activity monitor, it is always like 45% cpu load - wow, kind of high, I guess.
the whole thing is very frustrating and not “ubuntu - like”, because I face some extrem barriers - which should not be.
Maybe you can include a kind of hint/recommendation, that MATE 15.10 should not be installed under 1.67 Ghz PPC or even maybe only for G5 machines. (tried live CD on a powerbook g4 1.67Ghz, 2GB Ram, 128MB ATI 9600gfx) and it was like 12% load on CPU.
anyway, before I install Debian 8.2 again (which has no sound running, no apple function-key support and bad trackpad support) - maybe someone could help me to get MATE 15.10 run stable and a bit more snappy / faster?
I have not found the app that controls the services, that are loaded on startup, would be cool, if someone can give a hint on that, too.
edit: maybe I need to add
Linux radeon.modeset=1 video=radeonfb:off video=offb:off video=1024x768-32 radeon.agpmode=-1 in yaboot-config?
