I have laptop Acer spin 5 "Spin SP513-54N" and had ubutnu 21.10 installed on it. At first, the touch pad and touch screen were not working so I followed the instructions in this page and it fixed it: https://sciactive.com/2020/12/04/how-to-install-ubuntu-on-acer-spin-5-sp513-54n-for-the-perfect-linux-2-in-1/
sudo gedit /etc/default/grub
Add pci=nocrs to the end of the options for GRUB_CMDLINE_LINUX_DEFAULT. It should look something like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nocrs"
I tried every fix I could possible find online but nothing works. plz help me with this issue as the computer is not usable without touch pad
