Touchpad doesn't work

Post by cm1 »

My touchpad stopped working in LMDE2 the other day on my laptop. It was working fine one day, and then next day I booted up the laptop, it wasn't working. When I booted into Windows (laptop is configured for dual-boot), the touchpad works just fine.

I booted into the LMDE2 image/installer I had on my USB, and the touchpad worked fine while booted into it. I then wiped the LMDE partitions on the hard drive, reinstalled LMDE2 fresh from scratch & booted from the hard drive without touching or changing any settings. The touchpad is still not working!

A USB mouse plugged in works just fine. "Enable touchpad" is ON in the system settings control panel. The command:

Code: Select all

grep "Name=" /proc/bus/input/devices
doesn't list anything that looks like a touchpad.

This command returns nothing:

Code: Select all

egrep -i 'synap|alps|etps|elan' /proc/bus/input/devices
Pressing Fn-F7 (trackpad symbol with an X through it) doesn't do anything.

Any idea what might be going on and how I can fix this? Thanks in advance.

I temporarily fixed it by going into Windows, rebooted into LMDE and the Trackpad started working again in LMDE2.

I spoke too soon.

After booting into Windows, and rebooting into LMDE2 the trackpad works - for that boot. If I shut down, and start back up into LMDE2, the trackpad doesn't work. I'll need to boot again back into Windows to get it to work in LMDE2!

Anyone has any idea why this is happening, and how to permanently keep it working without having to boot into Windows?

Windows reports the trackpad device ID as: acpi\ven_etd&dev_0109 ... the trackpad works perfectly & consistently in Windows.

Fixed it after reading: https://bugzilla.kernel.org/show_bug.cgi?id=81331

I added "i8042.kbdreset=1" to kernel parameters in /etc/default/grub
