I upgraded from Fedora 41 to 42. During this process, my touchpad, which I normally activate with the FN+F2 key combination, stopped working. I haven’t filed a bug report or done any debugging because I’m not knowledgeable in this area. How can I solve this issue or perform debugging?
Edit: The issue is resolved when I change the touchpad protocol to PS/2 via the BIOS, but that’s a rather outdated protocol, so I want to use I2C instead. However, it’s not working.
The output of lsmod | grep i2c_hid is as follows:
i2c_hid_acpi 12288 0
i2c_hid 49152 1 i2c_hid_acpi
The drivers are loaded, but when I run sudo dmesg | grep -i -e i2c -e touchpad -e synaptics -e elan -e hid, there’s no mention of the touchpad. In other words, the system doesn’t detect it.
