Sorry, not sure you you will take it as a bug, but Ubuntu 20.04.3 (so as 21.*)
doesn't recognize the touchpad on my Lenovo S145 and I have to tweak it (I
found this tweak on web):
1. sudo gedit /etc/default/grub
2. There I change GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to
GRUB_CMDLINE_LINUX_DEFAULT="i8042.nopnp=1 pci=nocrs"
3. sudo update-grub
4. restart
Need to mention, until the above, the touchpad was not detected by the
kernel(less /proc/bus/input/devices), and my system starts much longer
after that.
Sincerely think this operating system could be better.
I'll delete this appeal if you won't admit it a bug
