Ubuntu Black Screen on Resume-After-Lid-Close

webmanoffesto · 06-04-2015, 06:51 PM

I have my ASUS K55A Laptop set to "no hibernate to disk" only "suspend to RAM". However, after I close the laptop lid, I still get a black screen. The weird thing is sometimes, after a hard reboot, on the first resume-after-lid-close it DOES resume, however on the second resume-after-lid-close I get a black screen. Also, there are times when I have a YouTube movie playing, and on a resume-after-lid-close which gives me a black screen I can hear the YouTube video playing ("behind" the black screen). I am not using an external monitor.

Asus K55A Laptop Ubuntu 14.04.2 LTS Gnome

When I did CTRL + ALT + F1 I got a login prompt. I entered username and password, and then received the appropriate user prompt. Then I did CTRL + ALT + F7 and was presented with the Black Screen.

It's a Black Screen with a Glow, and if I press Fn-F7 (screen off) the glow shuts off.
This is the same as when I Reboot and Login, I then see that glowing-black-screen, and then the purplish Gnome Desktop appears.

Since it's a glowing-black-screen that tells me the screen is not off, it is on and "showing me" a black or blank image.
