I have the same problem with Dell Inspiron 3847, but I've solved using an older keyboard, not Dell.
I suspect the problem is in Dell keyboard and/or mouse. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1330255 Title: Unable to Detect USB Mouse and Keyboard Status in xorg package in Ubuntu: Confirmed Bug description: When I boot into ubuntu 14.04 LTS, most of the time it does not even recognize the USB mouse and keyboard. It only recognizes them about one-third of the time, and it will have a message that pops up that says Connected: Wired Connection 1 That's when I know it recognized the mouse and keyboard. Otherwise I don't see any message and nothing works. I have to do a hard shutdown (i.e. hold the power button down until the computer turns off) because I cannot restart the computer with the keyboard or the mouse.
