I can confirm this bug as well (using Linux Mint 20, Kernel 5.4.0-48-generic) with the same laptop.
However, I can offer a partial workaround: After adding "i8042.nomux i8042.notimeout" to the kernel command line (i.e. via GRUB_CMDLINE_LINUX in /etc/default/grub), the trackpad will be properly recognized and shown in the dmesg output. It still won't work out of the box BUT after suspending and resuming the laptop, it basically works. Occasionally, keyboard and/or trackpad will stop working which can be fixed by a reboot. The type of trackpad seems to be an Elantech Touchpad hw version 4. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893663 Title: touchpad not detected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1893663/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
