El trackpad no funciona en Ideapad Flex 5 - Ubuntu 23.04

Recientemente compré unLenovo Ideapad Flex 5. Eliminé instantáneamente Windows 11 Home e instalé Ubuntu 23.04. El único problema: el trackpad no funciona.Ubuntu ni siquiera reconoce el trackpad, como puede ver en el lsusbresultado a continuación:

Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 004: ID 0bda:4853 Realtek Semiconductor Corp. Bluetooth Radio
Bus 003 Device 003: ID 1c7a:0576 LighTuning Technology Inc. EgisTec EH576
Bus 003 Device 002: ID 093a:2510 Pixart Imaging, Inc. Optical Mouse
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 30c9:0053 Luxvisions Innotech Limited Integrated Camera
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Probé otras distribuciones de Linux; el mismo problema. Sin embargo, el trackpad funciona bien en el menú del BIOS, así que sé que no es un problema de hardware. He buscado por todas partes en internet y no encuentro nada.

Corrí sudo dmesg | grep modprobetras correr sudo modprobe i2c-hid-acpiy obtuve esto:

Para Lenovo Ideapad Flex 5 14ARE05, no se conoce ninguna solución, pero intentaría agregar a la línea de cmd del kernel "i8042.reset=1" según la descripción enhttps://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.8/+bug/1912880ese apagado forzado mientras se suspende recupera el panel táctil (aunque uso dicho reinicio i8042 en mi Lenovo Thinkpad Yoga S1 para arreglar lo opuesto, es decir, sin teclado/panel táctil después de un apagado forzado mientras está suspendido, vale la pena intentarlo. He usado este truco desde se informó).

También puedes probar "i8042.nopnp=1", como indica el registro dmesg del informe anterior:

 [ 0.602905] i8042: PNP: PS/2 appears to have AUX port disabled, if this is incorrect please boot with i8042.nopnp

También podrías intentarlo i8042.nomux=1entonces.i8042.kbreset=1

Es posible que también quieras informar el error al kernel de Linux ML o bugzilla.https://bugzilla.kernel.org/. Es posible que desees publicar tu salida de dmesg o al menos: sudo dmesg|grep -E "PS\/2|ACPI|hid|i8042"

Para el Lenovo IdeaPad 5 15are05,IdeaPad 5 15are05: el panel táctil elan no funciona en 20.04 ni en 18.04

modprobe i2c_hid echo "i2c-ELAN0001:00" > /sys/bus/i2c/drivers/elants_i2c/unbind echo "i2c-ELAN0001:00" > /sys/bus/i2c/drivers/i2c_hid/bind o agregue initcall_blacklist=elants_i2c_driver_inita la línea de cmd de su kernel (GRUB_CMDLINE_LINUX="" en /etc/default/grub (2020 podría arreglarse en sentido ascendente)

Para el Lenovo IdeaPad 3 14IIL05,https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe/+bug/1880172/comments/53, eso es:

agregando los siguientes argumentos a GRUB_CMDLINE_LINUX_DEFAULT.

"i8042.nopnp=1 pci=nocrs" (2020)

@SO_32 quizás quieras probar sin pci=nocrs. Los parámetros del i8042 no deberían afectar a los dispositivos wifi por sí solos.
