Alps touchpad doesn't work on HP/Compaq R3000Z laptop

The alps touchpad doesn't work on HP/Compaq R3000Z laptop, either
during installation or after it.
As installation begins, I can briefly see a text mode message about
"PS/2 Generic". Its so quick I didn't get all the message. But later
it comes up as "No Mouse". Overriding that setting in the installer
What is it with the large number of mouse issues in the Fedora
series??? Desktop, laptop, I've yet to install a version of Fedora
that didn't have some kind of mouse issue. Thankfully, FC3T3 finally
cures the mouse issues with the Intel D845PEBT2 desktop mobo (after 9
months). So its win one, lose one this time around.
ALPS touchpad support requires a kernel patch:
Original patch (note there are later fixes for module
As soon as it is in upstream support should work. You may find that
setting psmouse.proto=imps as a kernel argument enables basic support.
Can you check the output of /proc/bus/input/devices?
Do you have any PS/2 options in your BIOS?
ping - have you been able to test passing the psmouse.proto= to the
Can you also test psmouse.proto=bare as well as imps
I have a recent R3000z and the touchpad works if I use psmouse.proto=
imps or bare. This is running FC3 i386 and x86_64.
Gene, can you attach /var/log/boot.log and /var/log/dmesg, also the output of
I would have thought that the input layer would set to imps on ALPS touchpad h/w?
Related (or they are a dup of this report):
Created attachment 109275 [details]
/var/log/boot/log (acpi on)
Created attachment 109276 [details]
dmesg (acpi on)
Created attachment 109278 [details]
/proc/bus/input/devices (acpi on)
This was on i386 system since x86_64 is the same.
Gene note synaptics != alps, they are distinct.
You don't have a synaptics device entry in /proc/bus/input/devices,
but do have a mouse picked up - which I assume is the touchpad.
Can you clarify in comment #3 that the touchpad *only* works with
those psmouse.proto settings and acpi on, or which combinations of
those parameters work.
Oops ... sorry about the ALPS versus Synaptics ... that is why I added
my separate reports (although the actual problem may be the same cause).
Here is /proc/cmdline:
ro root=LABEL=/1 noapic psmouse.proto=imps quiet
Note: If I boot acpi=off, then the USB mouse is detected/works but
the Synaptics touchpad is not detected. If I then add i8042.nomux
both the touchpad and USB mouse are detected but my keyboard does not
seem to work.
If the original report is for a R3000z (Athlon64) notebook, then the
touchpad is likely to be the Synaptics as that is what I have.
