The title says it all... I'm having lots of issues after upgrading 9.04 to 9.10 - I want to reinstall without losing my files and I gave away my Ubuntu Disc and I can't make another one right now...
How can I force Ubuntu 9.10 to reinstall itself (without losing my information)?
EDIT:
The issues are: unresponsive mouse: [fixed by modding xorg.conf] and weird graphics issues which don't seem to be hardware or software, I can't tell. (specifically, bouncing lines on top of my screen and a loading bar on the shutdown screen - my friend says he has 9.10 and that the bar shouldn't be there.)
EDIT:
I ran sudo dpkg-reconfigure -phigh -a
and it didn't work. The following is my terminal's output. Any ideas would be welcome.
moshe@moshe-laptop:~$ sudo sh
