Last weekend, after successfully upgrading my 1 GHz PC from Debian stable to unstable, I got the crazy idea that I should upgrade the fully functioning Debian stable on my iBook (600Mhz, 384 Mb) to either Debian testing or unstable. I had already forgotten the udev problems I had encountered and finally solved on this Pentium box.
It was a bad idea. I did not succeed in getting the X configured -- I just had a black screen with a colored horizontal stripe on the bottom half of the screen. Reset, reboot and again. Reset, reconfigure and reboot. Again. And again.
Second try: I burned the CD for Arch Linux. Arch did not give me any more usable X. After some googling around I succeed in getting at least a weird split screen TWM on the screen instead of the now familiar black screen. But still I had no functioning keyboard nor was the touchpad functioning.
After this, I was willing to live on the command line for a while as the Arch at least booted extremely quickly. But then I realized the PPC repositories were not nearly as good and up-to-date as the repositories for 386 Arch.
Ok. After two days of experimenting I decided to go back to the point where I started all this. I had, after all, been quite happy with Debian stable...
