I am new to Ubuntu. I installed ubuntu 14.04 2-3 days before. And I am facing the problem when I insert the Data Card (USB Internet Dongle), my laptop stops working, even mouse pointer doesn't move, touch also doesn't work. I then reinstalled ubuntu. And still I am facing the same problem
Laptop Specs Acer Aspire V5 RAM : 6 GB HDD: 1 TB
USB Dongle Huawei E303
