OS: Ubuntu 20.04.1 LTS x86_64
Host: XPS 15 9575
Kernel: 5.8.0-36-generic
BIOS version: 1.13.0
Boot-loader: grub2

After rebooting Ubuntu on my XPS-15 9575, keyboard and trackpad does not respond for about 15 seconds, and sometimes requires an entire reboot to get keyboard responsive. The touchscreen still works and the system is otherwise responsive.

Have tried:

reinstalling xserver-xorg-input-all, by using the touchscreen to open a terminal, but problem reoccurs on startup

keyboard also becomes responsive when the screen is folded back and back forward, might have something to do with the 2-in-1 nature of the laptop

In order to get the keyboard/trackpad working on Ubuntu 20.04.1, the workaround is to add "blacklist intel_vbtn" to `/etc/modprobe.d/blacklist.conf.

I was able to find this link below that helped me to solve my problem. Workaround seems to be necessary for all but the latest linux kernels. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1822394
