I opened my laptop today to find that my arrow keys, excluding the left arrow, and Delete key are not functioning correctly. The down arrow brings up the notification that the trackpad was disabled, the delete key brings up the notification that the trackpad was enabled, and the up and right arrows don't seem to do anything.
I'm running Ubuntu 14.04, I have an Acer laptop, and the keyboard model is set to Generic 105 key (Intl) PC. The keyboard language is set to English(US). I tried changing the model to a few different ones, but it didn't solve the problem. I noticed that a lot of people had this problem in the past, but I couldn't find a solution for myself. If you experienced this problem recently, how did you solve it? Or do you have any ideas on how I may fix it.
Also, I have Ubuntu installed as my operating system and am not using a VM.
