I have a Asus S56CA laptop. When I bought this laptop, it came prinestalled with Windows 8 wich I updated to 8.1. I soon decided that Windows wasn't right for me and decided to use my old Ubuntu 12.04 LTS disk to install Ubuntu and experienced no problems with this. I then updated this to Ubuntu 14.04 LTS using sudo update-manager -d.

After this update I have had troubles waking up my laptop after closing the lid. I am either receiving a black, blank screen where all I can see is the mouse (The mouse can be moved) or the lock screen which I cannot interact with at all (Entering Password, moving mouse etc). I was wondering if anyone else has had this problem and how they got around it. If not, does anyone know a way to fix this and stop it from happening in the future.

Thanks all.

Welcome to askubuntu! Please help us help you by providing more information. I could be more helpful if I had the output of df -h and sudo fdisk -l for example. This appears to be a hibernation problem. Having the details of the disks in use and their mount locations will be helpful to us. – Elder Geek Jun 12 '14 at 16:33
Also I think you may have been intending on update-manager --dist-upgrade instead of update-manager -d – Elder Geek Jun 12 '14 at 16:36
Please edit and add the information to your question. There isn't enough room in the comments – Elder Geek Jun 12 '14 at 17:13
Have now added said info to question. – Robbie White Jun 12 '14 at 17:17
I do not think that df or fdisk info is needed for this problem --- seems a clear problem of graphic drivers. Try to see if this answer helps you. – Rmano Jun 12 '14 at 17:32

This can be a temp. fix by trying to avoid suspending. Do the following: Go to Dash then System Setting, power and the choose When lid is closed do nothing.

Thanks. I have set this and it appears to working okay now. I looked at the error that is displayed and it mentioned something about Kernel oops. I don't know what this means but maybe this could help? – Robbie White Jun 12 '14 at 16:35
More than likely. The exact error message is always helpful. – Elder Geek Jun 12 '14 at 18:26
