I was using the 2.6 kernels with no problems, but when I updated to the 3.0 kernel, my bootup failed. I can manually boot with ctrl+alt+f1 > startx and my login, but admittedly, i googled this and have no idea what I'm really doing. I have been trying to figure out how to go back to the old version, and eventually figured out the grub menu--i booted from all three 2.6 (.8, .10, and .11) editions of the previous version of ubuntu but they all had the same error as the 3.0 kernal.
I can get logged in manually once the boot fails, but when i get to my desktop, wireless is not responsive and will not connect, and portable hard drives do not mount and/or are unresponsive.
the previous version worked perfectly.
I use an asus netbook. it's an eee pc. i don't have two OSs on it. i had to go to another computer to get to the forum...
If the solution is simple, i just don't know what it is.
