This input device is unused even when the i2c-hid-acpi kernel module is blacklisted making the integrated ELAN touchpad (04F3:308A) not working at all. Since the integrated touchpad is managed by the i2c_designware input driver in the Linux kernel and you can't find a PS/2 mouse port on the computer I think it's safe to not use the PS/2 mouse port at all. Signed-off-by: Szilard Fabian --- I think the same patch could be applied to E4411, E4511 and E5511 too but sadly I can't test this theory. But these computers use the same UEFI updates so I think there isn't much difference in input devices. --- drivers/input/serio/i8042-acpipnpio.h | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/drivers/input/serio/i8042-acpipnpio.h b/drivers/input/serio/i8= 042-acpipnpio.h index 028e45bd050b..3f73fa69b8ce 100644 --- a/drivers/input/serio/i8042-acpipnpio.h +++ b/drivers/input/serio/i8042-acpipnpio.h @@ -618,6 +618,14 @@ static const struct dmi_system_id i8042_dmi_quirk_tabl= e[] __initconst =3D { }, .driver_data =3D (void *)(SERIO_QUIRK_NOMUX) }, + { + /* Fujitsu Lifebook E5411 */ + .matches =3D { + DMI_MATCH(DMI_SYS_VENDOR, "FUJITSU CLIENT COMPUTING LIMITED"), + DMI_MATCH(DMI_PRODUCT_NAME, "LIFEBOOK E5411"), + }, + .driver_data =3D (void *)(SERIO_QUIRK_NOAUX) + }, { /* Gigabyte M912 */ .matches =3D { --=20 2.42.0
