#LENOVO G50 MOUSE PAD NOT WORKING WINDOWS 10 INSTALL#

If you want to get your device working:įind your ACPI id by installing acpidump: sudo apt install acpidump There are a bunch of other folks having this type of trouble, as the elan touchpad is just too new to have mainline kernel support. I found that stock and HWE kernels for ubuntu 16.04 did not detect an elan device or any pointing device at all, indicating that there was something 'missing' in the i2c device detection in the 16.04 kernels.Īn install of 18.04 WAS able to see an elan device: user-Lenovo-ideapad-330-15IGM kernel: i2c_hid i2c-ELAN061C:00: i2c-ELAN061C:00 supply vdd not found, using dummy regulatorīut the touchpad did not work or register any input. To see if there is even a device detected.

Please look at your output for dmesg | grep i2c and dmesg | grep elan

Many elan touchpad ACPI device IDs are still not present in the kernel driver source for elan_i2c_core.c so there is no hope at this time to get a working touchpad without writing a dkms module (which did not work for me) or compiling a custom kernel. Windows Identifies it as a Elan HID over i2c device, the problem with detection on the 330 is a similar issue to the lenovo 320 laptop mentioned here: Lenovo Ideapad 320 - Touchpad doesn't workĪnd the solution is to patch the kernel similarly to what was done here: įYI: Unlike other elan touchpads in ubuntu, I found that modifying the boot parameters with i8042 options did not make a difference for this touchpad. The touchpad of the Lenovo 330 series is not detected at boot due to its ACPI id not being present in the kernel driver.

All hope is not lost! I have successfully recompiled the latest ubuntu 4.18.0 Kernel and added the ACPI id for the elan061C touchpad on the Lenovo 330-15igm that I own and now have a working touchpad.
