Ubuntu installation issues on HP Pavilion 11 x360 keyboard and touchpad problems
I chose to install Ubuntu on an old HP Pavilion 11 x360 2-in-1 laptop. The touchpad and keyboard functioned properly initially, but after the official setup only the touchscreen remained active while the keyboard and touchpad became unresponsive. Since keyboard input still works in BIOS, the issue likely stems from a Linux kernel or patch for both devices. I’m avoiding external hardware except during troubleshooting and would appreciate advice from experienced Ubuntu users on resolving this problem. Thanks!
I tested that setup and neither the keyboard nor the touchpad showed up. They eventually began functioning once I connected an external mouse, but only after unplugging and plugging it back in. After restarting the laptop, they stopped working again, even when I reused the external mouse. Any advice?
You notice entries about hardware after connecting peripherals. Pressing Shift+G may navigate deeper into the logs. Repeating device listings and plugging devices often reappears the internal keyboard and touchpad. Running `libinput list-devices` might trigger related actions.

sudo dmesg --human requires being part of the input group. If not, press Shift+G to navigate the log. To locate entries for your touchpad, type a query in dmesg using Slash (Shift+7) and press Enter. Use N to jump to the next match and Shift+N for the previous one. For instance, searching for "touchpad" in the output will show relevant results. If you need details about your mouse or touchpad, let me know.
Managed to run 'sudo libinput list-devices' successfully. Still learning Linux, but your notes are really useful.

They appear to be detected at least. Look for their device files in the kernel log—those listed after “Kernel:” should show up. After some online research, a potential fix is disabling ACPI (the third comment mentioned). This would be a last resort since ACPI is crucial. Before making changes, check what errors the kernel reports. Updated November 21, 2020 by elsandosgrande Added further details
