Re: xorg.conf help needed on Lubuntu 12.10 G4 nVidia
I don't mean to sound too rude, but lubuntu-qa have form for not reading documentation properly!!! I'm not pressing the panic button yet.
Snd_powermac is force loaded (twice) in /etc/modules so remove this is you don't have that kind of card. You do have a blacklist.local.conf file listed and I bet it contains sound modules so remove that file or the sound module contents.
There will be four possible combinations of sound modules. It is simply a case of researching if the sound module names have changed (look at the PowerPC kernel developers list as I know work has been done on them) and trying each combination if the autoloading is not working properly.
