Hello Kai, I compiled your test kernel and there was a warning while installing it that could be referred to the problem we are living. I am copying the output lines of:
>> sudo dpkg -i linux-image-5.9.0-rc3+_5.9.0-rc3+-1_amd64.deb This is the output: --------------------------------------------------------------------------------- update-initramfs: Generating /boot/initrd.img-5.9.0-rc3+ W: Possible missing firmware /lib/firmware/rtl_nic/rtl8125b-2.fw for module r8169 Sourcing file `/etc/default/grub' Sourcing file `/etc/default/grub.d/init-select.cfg' Generating grub configuration file ...

I tried to contact Lenovo Support team and their answer is really disappointing. They said Lenovo IML 15 is not certified for linux systems, so, I should use Windows instead. Thing is that I don't like their solution -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1853277 Title: Lenovo ThinkBook 14-IML Touchpad not showing up in /proc/bus/input/devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1853277/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
