touchpad not working. i've been on it off and on, recently upgraded to 5.4.52.

the touchpad works perfectly in systemrescue 6.1.5.

cat /sys/devices/pci0000:00/0000:00:15.1/i2c_designware.1/i2c-9/i2c-SYNA8004:00/uevent

in systemrescue:
DRIVER=i2c_hid
MODALIAS=acpi:SYNA8004:PNP0C50:

in slackware:
MODALIAS=acpi:SYNA8004:PNP0C50:

the driver is missing in slackware, is this a kernel issue?latest?d=yIl2AUoC8zA latest?i=RjXJdaAlgqk:YplxxXg2XSM:F7zBnMy latest?i=RjXJdaAlgqk:YplxxXg2XSM:V_sGLiP latest?d=qj6IDK7rITs latest?i=RjXJdaAlgqk:YplxxXg2XSM:gIN9vFwRjXJdaAlgqk
