"If you have a machine that Ubuntu 10.04 actually works on, then you
should get plenty of use out of it, congrats, you are one of the lucky
ones, just whatever you do, don't change any hardware or anything else
without first backing up everything on any and all partitions and OS'es
installed on said computer.
If Ubuntu won't work on your machine...well...try all the fixes if you
want, or read the thousands of posts on the subject and come to the
conscious decision to try something else, plenty more Linux OS'es out
there. But this one is hit-or-miss for now."
"hit or miss for now"? Who deluded you with hobbyware hope?
It's hit or miss forever.
