Hi,
Apparently you will need to add pci=nocrs to the GRUB_CMDLINE_LINUX_DEFAULT inside /etc/default/grub and the run from terminal:
sudo update-grub
then reboot
But probably you will have (also) to create a file to blacklist elants_i2c module. One single command from terminal will do that for you:
echo "blacklist elants_i2c" | sudo tee /etc/modprobe.d/unneeded-modules.conf
Then you have to reboot. To remove the file in case is not helping:
sudo rm /etc/modprobe.d/unneeded-modules.conf
Other people got it working like this
