Question

After upgrading from Ubuntu 20.04 to Ubuntu 20.10 my laptop keyboard and mouse are not working. How do I fix it? Please help me.

Answer 1

using Linux Kernel v5.4 instead of 5.8 seems to fix the issue for me.

joseph@joseph-X541UJ:~$ uname -r
5.4.0-52-generic

I've installed Kernel 5.8.16 and yes the keyboard and touch mouse works very well.

joseph@joseph-X541UJ:~$ uname -r
5.8.16-050816-generic

I recommend anyone facing the same issue to mark that on launchpad bug link, so it can draw more attention from developers.
