Asus TUF Ubuntu 18.04.1 elantech mouse freezes frequently

I purchased a ASUS TUF FX504GE laptop and dual booted it with Ubuntu 18.04.1 .After which my elantech touchpad stopped working.I updated my kernel to 4.20.6, after which it does work,but freezes unexpectedly for 3-4 minutes. After searching about this problem, for some people updating to 4.20 was the solution but still there are peoplefor whom this didn't work. Some solutions recommended running xinput. My results are below:

⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ ELAN1200:00 04F3:3090 Touchpad         	id=13	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Power Button                            	id=6	[slave  keyboard (3)]
    ↳ Asus Wireless Radio Control             	id=7	[slave  keyboard (3)]
    ↳ Video Bus                               	id=8	[slave  keyboard (3)]
    ↳ Video Bus                               	id=9	[slave  keyboard (3)]
    ↳ Power Button                            	id=10	[slave  keyboard (3)]
    ↳ Sleep Button                            	id=11	[slave  keyboard (3)]
    ↳ USB2.0 HD UVC WebCam: USB2.0 HD         	id=12	[slave  keyboard (3)]
    ↳ Asus WMI hotkeys                        	id=14	[slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard            	id=15	[slave  keyboard (3)]

The output shows id=13 as ELAN1200 touchpad. For the solutions suggested, this was wrongly set to PS/2 etc etc. But for me this value is correct. I need to solve this issue.
