[SOLVED] System does not recognize Synaptic touchpad

clcbluemont · 09-10-2010, 05:22 PM

A cat of /proc/bus/input/devices just shows the keyboard and pc speaker. I am running the 2.6.30.9 kernel on a RHEL 5.4 system. The stock kernel works fine. I have compared the kernel config files and do not see anything different in the INPUT Device area. Could it be that USB mouse driver is interfering? Is there something out side the INPUT Device section that the synaptic touchpad needs?

Hi clcbluemont, Welcome to LQ. I believe this line may be causing your problem.

Code:

# CONFIG_MOUSE_PS2_SYNAPTICS=y

Try uncommenting that line.

Good luck. ;-)

That did not help. Still nothing in /proc/bus/input/devices. I am going to try the RedHat 2.6.18-164-3 config file with the 2.6.30.9 kernel and see if that helps. In the end I need to make this kernel as trim as possible though and I am not sure what it is missing. Thanks for the catch though.

You could also try diff with the two config files.

Good luck. ;-)

This diffs are huge. I have run a real small kernel. Using the 2.6.18.8 RH config file recognizes the Synaptic touchpad. I am going through the diff now, but wow what a task.

Problem solved. I have attached my config file. This is an always On system and did not think I need power management.
With ACPI enabled:
PNP: PS/2 Controller [PNP0303:PS2K,PNP0f13:PS2M] at 0x60,0x64 irq 1,12

Without:
pnp: no ps/2 controller found. probing ports direct

Glad you got it sorted.

Good luck. ;-)
