I had a similar problem when I upgraded. I don't remember everything I had to change, but http://www.alexhudson.com/documents/linux-2_6-upgrade reminded me of one thing. If you have a ps/2 mouse, you need to make sure that the psmouse module is being loaded. You can do that on the commandline by running "modprobe psmouse". If that fixes the problem, and you're running Debian, you can have it load the psmouse module automatically on reboot by added "psmouse" to /etc/modules. > A related issue is that I note that dist-upgrade now wants to install > a new 2.4 kernel.

You can easily manage multiple kernels in /etc/lilo.conf. Here's a section from mine that does it: default=linux-2.6.8-1 image=/boot/vmlinuz-2.4.18-bf2.4 label=Linux read-only image=/boot/vmlinuz-2.4.25-1-686 label=linux-2.4.25-1 read-only initrd=/boot/initrd.img-2.4.25-1-686 image=/boot/vmlinuz-2.6.8-1-686 label=linux-2.6.8-1 read-only initrd=/boot/initrd.img-2.6.8-1-686 image=/boot/vmlinuz-2.6.8-2-686 label=linux-2.6.8-2 read-only initrd=/boot/initrd.img-2.6.8-2-686 Note that the key is to set the image to /boot/vmlinuz* instead of /vmlinuz. Hope that helps... Walt Attachment:
