Hardware • Touchpad issues on Latitude 5550.

I have a Dell Latitude 5550 that I installed Debian 12.5 on. I've noticed that running Debian, I am unable to use two-finger scrolling on the touchpad. Having looked through the output of xinput, the only input device I've seen related to the touchpad is PS/2 Generic Mouse. I have tried using the Ubuntu 24.04 Live CD on this same laptop, and the touchpad (with two-finger scrolling) works correctly, and shows up as a device using the i2c-hid driver.

So far, I've tried the following, to no avail:

• Switching to Sid and updating
• Compiling and installing the latest version of both libinput and the libinput X driver
• Compiling and installing the latest stable kernel (6.9.5)

I've looked through dmesg, and haven't seen any messages that jumped out to me as being particularly useful, relating to i2c or hid.

At this point I'm pretty much out of ideas for what else I should try, so I would appreciate any input. Thanks!
