After update, touchpad doesn’t work
OK, I read the article and I have linux-4.20.arch1-1-x86_64.pkg.tar.xz in the directory cd /var/cache/pacman/pkg/
But I’m unsure how to go back to this version from the 4.20.1 version.
Do I just use:
sudo cd /var/cache/pacman/pkg/ sudo pacman -U linux-4.20.arch1-1-x86_64.pkg.tar.xz
Do I need to unzip this file and run sudo pacman -U linux-4.20.arch1-1-x86_64.pkg instead?
no o.k. like you post:
sudo pacman -U /var/cache/pacman/pkg/linux-4.20.arch1-1-x86_64.pkg.tar.xz
or install downgrade script:
sudo pacman -S downgrade
and may downgrade linux-headers to the same version can provide from problems.
Nevermind. I should have read the WHOLE article you referred me to. I went back and read it again TO THE END and saw the part about Acer computers, which mine is. As it said, I went into the BIOS and changed the touchpad mode to “basic” and that solved the problem without reverting to an earlier kernel.
Thanks for the help from both of you, especially you joekamprad!
