I faced an issue with yum update failed. While updating through yum , My server power went down. Hence, all packages corrupted. I found below command to fix this issue.
# yum check dependencies \
| grep 'has missing requires' \
| sed 's/.\+has missing requires of //' \
| sed 's/ [=<>].\+//' \
| while read dep; do yum -y install "$dep"; done
Recently installed centos7 on my Laptop. But my laptop touchpad is not working, after a couple of days.
I’m glad this is fixed in CentOS 7.
I found a fix for F22 though, on askubuntu.
I had to tweak it a bit for Centos 7.
Here we go :
add i8042.nopnp at the end of the options of GRUB_CMDLINE_LINUX
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
echo “blacklist i2c_hid” | sudo tee /etc/modprobe.d/i2c-hid.conf
sudo depmod -a
sudo dracut -v -f
echo “synaptics_i2c” | sudo tee -a /etc/modules
Reboot and the Laptop Touchpad should work.
