I recently bought an Acer Aspire V5-121.

Installation went smoothly. But on rebooting I found the following issues:

  • Wifi did not work
  • USB 3.0 did not work
  • Touchpad did not work

Fix for Wifi:

In KDE Menu, type `driver`, to bring up the Additional Drivers link for installing Proprietary drivers. Choose to install the Broadcom STA wireless driver. On installing this driver and rebooting, USB 3.0 too started working.

For enabling Touchpad, all I needed was to press Ctrl-Fn-F7
