My upgrade from jaunty to
karmic was not quite rosy.
My man two problems were that my sound and touchpad stopped working.
Thankfully its all sorted out now (I hope).
My touchpad wasn't working because of using the wrong kernel - after upgrading to karmic, it didn't boot using the karmic kernel by default, I had to use grub editor to change that.
But then I could not boot. I had to go fix up my grub menu:
sudo vim /boot/grub/menu.lst
I had
title Ubuntu 9.10, kernel 2.6.31-14-generic (recovery mode)
root
in stead of
title Ubuntu 9.10, kernel 2.6.31-14-generic (recovery mode)
root (hd0,0)
(it was complaining that it could not find a kernel image at the specified location or something)
the sound was also related to using the wrong kernel, but also due to some pulsaudio issues see
HOWTO: PulseAudio Fixes & System-Wide Equalizer Support - Ubuntu Forums[update]mmm... the first kernel update broke it again :(
I finally heeded Robert's advice to do:
sudo update-grub
