Anything about Ubuntu, Centos, openSuSe and Fedora

Then another issue is wireless network RTL8723BE drops after each connection, but this article is about the touchpad: the ElanTech Touchpad, which by default not functioning well. Issues like there’s no switch off touchpad option in Ubuntu settings, multi-touch is not working, neither the scrolling.
Now to fix this issues, here’s the guide:
1. First, download the patch for the touchpad here.
2. Install dkms (if you haven’t done it yet)
sudo apt-get install dkms
3. Go to the directory where you store the file and perform the following:
sudo dkms ldtarball psmouse-elantech-x551c.tar.gz sudo dkms install -m psmouse -v elantech-x551c
4. Then reconfigure the driver
sudo rmmod psmouse sudo modprobe psmouse sudo update-initramfs -u -k all
