I think this is the driver for your Acer's Radeon card but I'll wait for the output of lspci | grep -i VGA.

Which Radeon card do you have?

Sorry I don't know how to check for my card the way you mentioned but I checked device manager and it says AMD Radeon(TM)HD 6520G

How do I install my Radeon card driver, do I do this in Windows or Ubuntu? The only screen I can get to type anything in on Ubuntu is the Grub where it gives the options like 'Try Ubuntu without installing' I can type e to edit. The only keyboard keys that work are the ones mentioned at the bottom of the grub, all others do nothing. I am trying to read and familiarize myself with all the technical lingo "kernel" "bios" etc. I read the article mentioned below and a lot of entries about the purple splash screen but didn't find anything I thought I could apply. I noticed the GNU GRUB says Version 2.02~beta2-9Ubuntu1.3 does this mean this version of Ubuntu is a beta version? Just wondering.

You would install the driver for Ubuntu. That's the driver I found in the previous post.
Download the driver. It should put the zip file in your Downloads directory.
If not it will put it in your Home directory.

You can install it if holding down Ctrl + Alt + F2 works for you. That should put you in command-line mode only.
Once your in commandline mode only I'll be able to guide you through form there and help you to find where the driver is and install it.

What version of Ubuntu do you have?

I have Ubuntu 14.04.3 desktop-amd64. I downloaded the driver and it is in my downloads. ctrl+alt+F2 doesn't work but Grub has a choice at the bottom says 'c' for a command line and it says Tab shows a list of supported commands. Hope that will work. Thanks for sticking with me, this is somewhat frustrating to me, I'm not a young newbie so takes a bit to wrap my head around some of this.

Good that the driver is in your downloads directory.
I downloaded the driver also-

Since Ctrl+Alt+F2 didn't work for you go ahead and choose 'c' for a command-line prompt.

Once you unzip the driver it should have this description.

Code:
amd-catalyst-13.12-linux-x86.x86_64.run
To unzip the driver type:

Code:
cd Downloads
ls   (ls will list and show you what you have in your downloads directory)
unzip amd-catalyst-13.12-linux-x86.x86_64.zip (and hit Enter)
After you have the driver unzipped it will be in the form of a shell script.
You will have to run that script as root.
In command-line type:

[CODE]sudo and press Enter and type in your password
(your password will not show.......that's normal)
If your not in your Downloads as 'root' than just type cd Downloads while your root.
To see the script in the command-line type ls

Than type:
Code:
./amd-catalyst-13.12-linux-x86.x86_64.run (exact name of driver/script.
-::-The script should take off and an Installer should open up and walk you through installing the driver.-::-

If the script tells you permission denied it's because you don't have permission to run it or the script will have to be made executable by using the chmod command.
To make the script executable type:

Code:
chmod u+x name of driver/script (amd-catalyst-13.12-linux-x86.x86_64.run) w/o the brackets
Than run:
Code:
./amd-catalyst-13.12-linux-x86.x86_64.run
Once the script start's to run you will see the Installer open up and ask for your password.
Here's a pick of what it looks like on my system.

Is this a password I choose at this point and time? Also I just have to ask this..if I do something wrong it won't mess up my laptop will it? I assume it won't since all this is actually being done on the usb stick not my hard drive but you know what they say about assuming something, I figure better to ask.

Are you saying that by making the script executable it will give me permission to run it if permission has been denied?

This is/was the password that you choose when you installed Ubuntu.

If your only running Ubuntu live off of the usb memory stick no; it won't mess up your laptop.

Here's more information to help you if this is what you have going on.
If Ubuntu is just running off of the usb stick and not installed; the link should help.

There is a lot that might be wrong if it just freezes there. One thing you might try is to use Ubuntu in its fail-safe mode. You can do so (from last I remember) by hitting F4 on the Ubuntu menu, and selecting fail-safe mode. This will run the live CD in "safe graphics" mode which is generally the problem with Live CD environments.

One thing you can do to troubleshoot this problem is to press F8 when the purple screen appears. This will show you the boot process allowing you to see exactly where the boot process hangs.

Plymouth, (the program that displays the purple screen with dots) can cause issues with radeon cards as it changes the video modes. When you hit "e" to edit the grub line, remove the 'quiet spash' and let it display all messages...

Thanks NGIB-

I had forgotten that Plymouth could be contributing to this hang issue.

I hope that removing quiet splash works for op.-

OK so do I remove quiet splash before attempting the graphic card driver I downloaded?

Yes:-

If that doesn't allow Ubuntu to boot remove nomodeset too if you haven't already.
