Ubuntu – Laptop Screen Black After Suspend


I'm a new user to Linux and i am running into an issue with suspend on my laptop with the following configuration

Model : HP Envy m6 (AMD A10-4600M APU with Radeon HD Graphics)

Operating System : Ubuntu 14.04 LTS

Issue : When I close the lid of my laptop, or manually attempt to put it in suspend, it will shutdown like normal. However, when I try to resume my screen will remain dark.

I've looked around and seen several articles that have information about this, but nothing that directly relates to what I'm experiencing. I've tried a few of the other "fixes" and nothing has worked so far.

ANY help that can be provided will be appreciated!

I have a HP-Probook 5420s running with a AMD graphic card and running the open source drivers, I tried digging around a bit and tried most solutions but to no avail however after reading the comment 30 on https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1283938 it worked.

This comment shows a temporary fix in which by going through settings security & privacy you can uncheck require password when waking from suspend and from blank screen. I only unchecked returning from blank screen and for the moment my systems seems to have returned to normal! I will update if anything abnormal appears. Hope this can help somebody.
