I recently purchased a Lenovo Ideapad Flex 5. I instantly removed Windows 11 Home and installed Ubuntu 23.04. Only problem: the trackpad isn't working. Ubuntu doesn't even recognize the trackpad, as you can see from the lsusb output below:

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

I've tried other linux distros; same problem. The trackpad works fine in the BIOS menu however, so I know it's not a hardware issue. I've looked everywhere online and I can't find anything.

Edit

This question is a duplicate but with no answer. Someone please help me, I really need this to work.

I ran sudo dmesg | grep modprobe after running sudo modprobe i2c-hid-acpi and got this:

For the Lenovo Ideapad Flex 5 14ARE05, no known workaround, but I would try to add to the kernel cmdline "i8042.reset=1" per the description in https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.8/+bug/1912880 that forced shutdown while suspend get the touchpad back (though I use such i8042 reset on my Lenovo Thinkpad Yoga S1 to fix the opposite ie no keyboard/touchpad after a force shutdown while suspended, it is worth a try. I have used this hack since it was reported ).

You might also want to try "i8042.nopnp=1" as the dmesg log from the above report tells:

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

You could also try i8042.nomux=1 then i8042.kbreset=1

You might also want to report the bug to the Linux kernel ML or bugzilla https://bugzilla.kernel.org/. You might want to post your dmesg output or at least: sudo dmesg|grep -E "PS\/2|ACPI|hid|i8042"

For the Lenovo IdeaPad 5 15are05, IdeaPad 5 15are05 - elan touchpad not working on 20.04 nor on 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 or add initcall_blacklist=elants_i2c_driver_init to your kernel cmdline (GRUB_CMDLINE_LINUX="" in /etc/default/grub (2020 might be fixed upstream)

For the Lenovo IdeaPad 3 14IIL05, https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe/+bug/1880172/comments/53, that is:

adding the following arguments to GRUB_CMDLINE_LINUX_DEFAULT.

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

@SO_32 you might want to try without pci=nocrs. i8042 parameters ought not to affect wifi devices on its own.
