Hello nora, from your dmesg in commment #10: [ 0.000000] Command line: BOOT_IMAGE=/vmlinuz-5.4.0-58-generic root=/dev/mapper/vgubuntu-root ro i8042.reset quiet splash vt.handoff=7
it looks like you're still using the "i8042.reset" parameter like in comment #4, not the "i8042.nopnp". Can you help us to check again? If "i8042.nopnp" is not working for you (which you should see in your dmesg if added properly), the last trial and error would be adding "i8042.noloop i8042.nomux i8042.nopnp i8042.reset" to GRUB_CMDLINE_LINUX_DEFAULT Thanks [1] https://wiki.gentoo.org/wiki/Synaptics -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1909898 Title: No response from TouchPad in 'Acer Aspire 5 A517-52G-79Z5' after installing Ubuntu 20.04.1 LTS Status in linux package in Ubuntu: Incomplete Bug description: If I remember correctly the touchpad was already not responding when booting into Ubuntu from USB stick.

In the cat /proc/bus/input/devices > ~/devices output I could not find any 'touchpad' entry. Output file 'devices' is attached.
