Description:
Hello, I have a new Laptop since kernel 5.7.2-arch1-1. Now It is 5.7.7-arch1-1 and the touchpad is still not working. Laptop manufacturer: Asus Model: ROG-Zephyrus-G15 GA502IV It looks like kernel recognizes the touchpad but doesn't enable it. # dmesg | grep -i elan [ 4.830134] i2c_hid i2c-ELAN1205:00: supply vdd not found, using dummy regulator [ 4.830150] i2c_hid i2c-ELAN1205:00: supply vddl not found, using dummy regulator And the device doesn't appear in the input devices list. Looks like kernel bug. Touchpad works fine in Windows (have a dual-boot). Fast boot is disabled in BIOS. |

Touchpad is missing in the 'xinput --list' log.
In the mainline kernel, liquorix, or my own 5.8.x kernel .
Can be fixed by adding i8042.nomux=1 i8042.reset to kernel parameters.
Edit: The device is i2c-ELAN0501.
