I have a dual-boot of windows 7 and Ubuntu 11.10. AMD Phenom-II 4-core processor, and an Asus motherboard.
So here's what happens, I turn on my computer my machine does its start-up process, then the grub comes up and I choose Ubuntu. The Ubuntu logo comes up with the five dots below it. It will do this for 15 seconds, then I get a screen with different processes starting such as Bluetooth and components starting up and all are accepted, then it will freeze on a midi process with this text.
*Starting TiMidity++ ALSA midi emulation... [OK]
I left it like this for 8 hours and there were no changes on the screen. I have tried some fixes for issues similar to mine but none have worked.
