I have recently performed a large number of updates to my Debian Linux box, including a kernel update and a change from Stable to Testing.

cat /dev/input/mice no longer returns anything, giving a "No such device" error. This also seems to cause startx to fail due to a lack of a core pointer.

I've done some searching, but I can't find much that helps. Rerunning the X configuration program doesn't help, and none of /dev/psaux or /dev/input/mouse* work either.

udev is installed, but hotplug appears to conflict with it, and is thus not installed. I am not using gdm.

If there's any more information I can provide, I'd be glad to... I've been working on this for hours with no success.

Update: mdetect -x gives no results.
Update 2: modprobe psmouse doesn't return an error, and psmouse appears in lsmod, so this would be the module used... I think.


Okay, managed to solve it myself eventually... the automatic update to udev broke it, because my kernel still wasn't new enough. Updated the kernel again and the mouse works again.
