FIX > yum update failed with error in CENT OS 7 , Not loading into GUI Mode.

Published September 19, 2017 by Siva

Hi Friends,

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

Thank You

Touchpad not working On Centos 7 (Dell Inspiron 15 3000)

Published September 7, 2017 by Siva

Hi All,

 

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 :

edit /etc/default/grub

add i8042.nopnp at the end of the options of GRUB_CMDLINE_LINUX

then run

Code:
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.
