Description of problem:
I have a Compaq R3000Z notebook with an ALPS Touchpad mouse which is
not recognized by the FC3 kernel. I've tried several versions
including the latest and none will recognize the mouse.
After a lot of research I figured out that by recompiling the kernel
with the evdev and psmouse loadable modules rather than built-ins.
The process I use to get it working is documented here:
This just gets it recognized as a standard PS/2 mouse, I'm still
lacking the full ALPS Touchpad functionality.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot kernel
2. Attempt to use mouse either in text mode or X
Actual Results: Cursor never moves.
Expected Results: Cursor should move when using the ALPS touchpad
built into this laptop.
With the evdev and psmouse modules compiled as loadable modules the
mouse gets recognized as follows:
mice: PS/2 mouse device common for all mice
input: PS/2 Generic Mouse on isa0060/serio4
This mouse is NOT recognized by any FC3 kernels.
You need to rebuild the kernel with the alps.patch supplied with the
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem. Please update to this new kernel, and
report whether or not it fixes your problem.
If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.
I think this patch, or something equivalent, is in 2.6.12-1.1372_FC3 now.
