Bug Description

Using Cinnamon on 18.04 Beta 2. (Description: Ubuntu Bionic Beaver (development branch) Release: 18.04)

Touchpad not detected. Was also not detected in 17.10 but I thought that this was a Wayland problem, but obviously not...

Hi Joseph,

No luck... Still not working.

Updated via UKUU. I have attached the screenshot showing the kernel version
plus the list of input devices.

Cheers,
Dave

PS why doesn't the wiki suggest using UKUU to install upstream kernels? So
much easier to do.

Hi,

No luck. Still no touchpad :(

I was going to do a clean install of 18.04. Is this an idea?

Cheers

You can also try other i8042 parameters:

        i8042.unmask_kbd_data
                         [HW] Enable printing of interrupt data from the KBD port
                              (disabled by default, and as a pre-condition
                              requires that i8042.debug=1 be enabled)
         i8042.direct [HW] Put keyboard port into non-translated mode
         i8042.dumbkbd [HW] Pretend that controller can only read data from
                              keyboard and cannot control its state
                              (Don't attempt to blink the leds)
         i8042.noaux [HW] Don't check for auxiliary (== mouse) port
         i8042.nokbd [HW] Don't check/create keyboard port
         i8042.noloop [HW] Disable the AUX Loopback command while probing
                              for the AUX port
         i8042.nomux [HW] Don't check presence of an active multiplexing
                              controller
         i8042.nopnp [HW] Don't use ACPIPnP / PnPBIOS to discover KBD/AUX
                              controllers
         i8042.notimeout [HW] Ignore timeout condition signalled by controller
         i8042.reset [HW] Reset the controller during init, cleanup and
                              suspend-to-ram transitions, only during s2r
                              transitions, or never reset
                         Format: { 1 | Y | y | 0 | N | n }
                         1, Y, y: always reset controller
                         0, N, n: don't ever reset controller
                         Default: only on s2r transitions on x86; most other
                         architectures force reset to be always executed
         i8042.unlock [HW] Unlock (ignore) the keylock
         i8042.kbdreset [HW] Reset device connected to KBD port

Hi,

This is now solved.

Grub had somehow been changed to disable ACPI. Enabling that solved the
problem.

Thanks for your help.

Cheers,
Dave

Imagine how great it would have been if you had mentioned how did exactly you did that (enabling ACPI in grub)?
