after a long time, i give ubuntu hardy another chance. It feels good.
But i have still some problems.
The sound is too low. I followed the tutorials on the offical page for the wiki. https://help.ubuntu.com/community/MacBook
But that helped me not. 2nd problem is that the wireless driver not work anymore. I had once a package that works. It was from the madwifi side. It was a package that was called madwifi-ng. But there are now only packages with the title madwifi-ng txpower that doesn't seem to work. I have the macbook 2,1. And i don't can use the keyboard right, for example i can't write the at symbol for emails. I searched the whole day. I hope someone can help me. And the biggest problem is the heat! The macbook runs very hot.
I installed lm-sensors to look how hot the cpu is. That is what it says:
