Go to Menu, Control Center, Mouse, Touchpad. Check the box Enable Touchpad. If that doesn't help, look on your keyboard for a button with a rectangle & slash thru it (F6 or F8?). Press that button or hold down Fn first & that should turn touchpad back on.

What is the result for

Code: Select all

dmesg | grep -i elan

[abdemirza]

Here is the output of that command..

Reboot and use Grub to load a 4.15 kernel as this code will likely only work in 4.15

In terminal

Code: Select all

wget https://www.dropbox.com/s/tq0kyr7epns6ao6/mouse.tar.gz
tar -zxvf mouse.tar.gz
cd mouse
xed elan_i2c_core.c

Go to the end of the file, at line 1266 you should find

Code: Select all

	{ "ELAN061D", 0 },

Change the D to an E, so it is

Code: Select all

	{ "ELAN061E", 0 },

I am thinking it needs to be a capital E, save, exit test editor and continue

Code: Select all

sudo apt-get install build-essential
cp /usr/src/linux-headers-$(uname -r)/.config .
cp /usr/src/linux-headers-$(uname -r)/Module.symvers .
make -C /lib/modules/$(uname -r)/build M=$(pwd) modules
cd /lib/modules/$(uname -r)/kernel/drivers/input/mouse
sudo mv elan_i2c.ko elan_i2c.bak
cd ~/mouse
sudo cp elan_i2c.ko /lib/modules/$(uname -r)/kernel/drivers/input/mouse/
make -C /lib/modules/$(uname -r)/build M=$(pwd) clean

Reboot into a 4.15 kernel

After any 4.15 kernel updates do

Code: Select all

cd mouse
cp /usr/src/linux-headers-$(uname -r)/.config .
cp /usr/src/linux-headers-$(uname -r)/Module.symvers .
make -C /lib/modules/$(uname -r)/build M=$(pwd) modules
cd /lib/modules/$(uname -r)/kernel/drivers/input/mouse
sudo mv elan_i2c.ko elan_i2c.bak
cd ~/mouse
sudo cp elan_i2c.ko /lib/modules/$(uname -r)/kernel/drivers/input/mouse/
make -C /lib/modules/$(uname -r)/build M=$(pwd) clean

[abdemirza]

It is showing this error after the command

Code: Select all

abdemirza@Linux:~$ cp /usr/src/linux-headers-$(uname -r)/.config .
cp: cannot overwrite directory './.config' with non-directory
abdemirza@Linux:~$ 

[JeremyB]

Try

Code: Select all

cd mouse

Then run the commands

[abdemirza]

Every command executed and then I rebooted the system but it is still not working and I have tried these steps on different 4.15 kernels but did not worked for me

I get this output:

Any help, please?
