Mouse stopped working after system upgrade
After doing an apt-get upgrade on my Debian unstable system, my mouse no longer works. The cursor sits unmoved in the middle of the screen.
About 200 programs got updated, including KDE, so I'm not sure where the problem was introduced.
It's an ordinary PS/2 mouse, and yes, it works fine when I boot from a Knoppix CD.
Any ideas on how to troubleshoot?
