My graphics driver was not installed, so I went and tried to install it. I couldn't so I updated to Raring Ringtail (13.04)
As the title says, I'm getting a black screen and a possible GPU hang. The black screen occurs when I boot my laptop and once it completely boots (gets to the login screen) the screen says something like "PM Device: Failed to start error." and then the screen goes black. I know the computer is still on because I hear the amazing Ubuntu drum sound. This also happened when I installed Ubuntu using a live DVD. I heard the drum sound then, too. I was able to partially fix the problem by using an external moniter. After installing, I went to settings and turned on my laptop display. Everything seemed fine. But.. everytime I restart my computer I have to plug in the external screen and turn on the laptop display again. Obviously, this shouldn't happen. I also keep getting spammed with an intel-gpu.py error or something from apport. Could this have something to do with it?
I've tried looking up solutions but I haven't found any that work. Here are my specs:
Ubuntu 12.10 64-Bit
Acer Aspire V3 731-4473 (Full specs here: http://us.acer.com/ac/en/US/content/model/NX.M31AA.005)
I believe I installed this using the Boot Repair remix of Ubuntu, if you need to know that. Also, I had to erase Windows 8 completely.. because of the bane of my existance: UEFI. I used Legacy Boot to install and use Ubuntu.
If you need more information, please ask. Any and all help or suggestions are welcome. Thanks in advance.
