In the initial boot stage the integrated keyboard of Fujitsu Lifebook U728 refuses to work and it's not possible to type for example a dm-crypt passphrase without the help of an external keyboard. i8042.nomux kernel parameter resolves this issue but using that a PS/2 mouse is detected. This input device is unused even when the i2c-hid-acpi kernel module is blacklisted making the integrated ELAN touchpad (04F3:3092) not working at all. So this notebook uses a hid-over-i2c touchpad which is managed by the i2c_designware input driver. Since you can't find a PS/2 mouse port on this computer and you can't connect a PS/2 mouse to it even with an official port replicator I think it's safe to not use the PS/2 mouse port at all. Signed-off-by: Szilard Fabian --- I think the same configuration could be applied to Lifebook U748 and U758 too but I can't test this theory on these machines. --- 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/i8042-acpipnpio.h index 028e45bd050b..983f31014330 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_table[] __initconst = { }, .driver_data = (void *)(SERIO_QUIRK_NOMUX) }, + { + /* Fujitsu Lifebook U728 */ + .matches = { + DMI_MATCH(DMI_SYS_VENDOR, "FUJITSU"), + DMI_MATCH(DMI_PRODUCT_NAME, "LIFEBOOK U728"), + }, + .driver_data = (void *)(SERIO_QUIRK_NOAUX) + }, { /* Gigabyte M912 */ .matches = {
