I was checking through dmesg and saw that there is a suggestion to use the newer hid-rmi driver for touchpad for my laptop which is new.(Model: HP-15-BS576TX).
From dmesg:
[ 2.507282] psmouse serio1: synaptics: queried max coordinates: x [..5648], y [..4826]
[ 2.538726] psmouse serio1: synaptics: queried min coordinates: x [1292..], y [1026..]
[ 2.538729] psmouse serio1: synaptics: Your touchpad (PNP: SYN3251 PNP0f13) says it can support a different bus. If i2c-hid and hid-rmi are not used, you might want to try setting psmouse.synaptics_intertouch to 1 and report this to linux-input@vger.kernel.org.
[ 2.601437] psmouse serio1: synaptics: Touchpad model: 1, fw: 8.2, id: 0x1e2b1, caps: 0xf00123/0x840300/0x2e800/0x400000, board id: 3320, fw id: 2548310

So, I booted with kernel boot parameter "psmouse.synaptics_touchpad=1". But, there seems to be little change and the touchpad continues using the old driver:
**:~$ cat /proc/bus/input/devices
I: Bus=0011 Vendor=0002 Product=0007 Version=01b1
N: Name="SynPS/2 Synaptics TouchPad"
P: Phys=isa0060/serio1/input0

B: PROP=1
B: EV=b

B: ABS=660800011000003
The dmesg with the kernel parameter psmouse.synaptics_touchpad=1 has not much information, except that touchpad continues using the old driver:

The i2c-hid, hid-rmi modules are available with the kernel - 4.13.0-19-generic
Any chance of getting this touchpad/trackpad to work with the newer hid-rmi driver? Thanks
