Recentemente comprei umLenovo IdeaPad Flex 5. Removi instantaneamente o Windows 11 Home e instalei o Ubuntu 23.04. Único problema: o trackpad não está funcionando.Ubuntu nem reconhece o trackpad, como você pode ver na lsusbsaída abaixo:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Eu tentei outras distros Linux; mesmo problema. O trackpad funciona bem no menu do BIOS, então sei que não é um problema de hardware. Procurei em todos os lugares online e não consigo encontrar nada.

Para o Lenovo Ideapad Flex 5 14ARE05, nenhuma solução alternativa conhecida, mas eu tentaria adicionar ao cmdline do kernel "i8042.reset = 1" de acordo com a descrição emhttps://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.8/+bug/1912880aquele desligamento forçado durante a suspensão recupera o touchpad (embora eu use a redefinição do i8042 no meu Lenovo Thinkpad Yoga S1 para corrigir o oposto, ou seja, nenhum teclado / touchpad após um desligamento forçado durante a suspensão, vale a pena tentar. Eu usei esse hack desde então foi relatado).
Você também pode tentar "i8042.nopnp = 1", conforme informa o log dmesg do relatório acima:
[ 0.602905] i8042: PNP: PS/2 appears to have AUX port disabled, if this is incorrect please boot with i8042.nopnp
Você também pode tentar i8042.nomux=1entãoi8042.kbreset=1
Você também pode querer relatar o bug ao ML do kernel Linux ou ao bugzillahttps://bugzilla.kernel.org/. Você pode querer postar sua saída dmesg ou pelo menos:
sudo dmesg|grep -E "PS\/2|ACPI|hid|i8042"
Para oLenovo IdeaPad 5 15are05,IdeaPad 5 15are05 - elan touchpad não funciona em 20.04 nem em 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 ou adicione
initcall_blacklist=elants_i2c_driver_initao cmdline do seu kernel (GRUB_CMDLINE_LINUX="" em /etc/default/grub (2020 pode ser corrigido no upstream)
Para oLenovo IdeaPad 3 14IIL05,https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe/+bug/1880172/comments/53, aquilo é:
adicionando os seguintes argumentos a GRUB_CMDLINE_LINUX_DEFAULT.
"i8042.nopnp=1 pci=nocrs" (2020)
@SO_32 você pode tentar sem pci=nocrs. Os parâmetros do i8042 não devem afetar os dispositivos Wi-Fi por si só.
