[Bug 1795292] Re: ELAN469D touch pad not working

Look at what this guy did:

to fix touchpad(not that easy if you havent compiled a kernel yet,not that difficult either)
1)download any kernel source from kernel.org(better choose the version that you are running presently or just the next updated version of it)
*use the command 'uname -a' to find the current kernel version

2)extract the kernel source and find the file
17.4.xx/drivers/input/mouse/elan_i2c_core.c

3)locate the line { "ELAN061C", 0 } edit that '61C' to '61E' and save that file
4)compile and use your new kernel
(this link may help if you are a newbie in kernel compiling.I simply followed it-https://medium.freecodecamp.org/building-and-installing-the-latest-linux-kernel-from-source-6d8df534...)
