Dave Lentz, thank you for your response. Regarding your comments https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1069299/comments/2 :
>"It's not an error with fglrx."

Yes, it is.

"Your GPU (RadeonHD 3100) is no longer supported by recent versions of fglrx: http://www.phoronix.com/scan.php?page=article&item=amd_catalyst_legacy2&num=1 "

For this bug report, quoting phoronix, quoting any other website that isn't AMD's, or not directly quoting from a AMD representative for this problem is, at best, conjecture.

So, let us talk about the facts. If one goes to the website http://support.amd.com/us/gpudownload/Pages/index.aspx and inputs Notebook Graphics
Radeon HD Series -> Mobility Radeon 3100 Series -> Linux x86 -> button Display Results one is brought to http://support.amd.com/us/gpudownload/linux/legacy/Pages/legacy-radeon_linux.aspx . As per this website:
"These updates will focus on resolving application specific issues and critical updates."

Not being able to use the driver, for whatever reason, is a critical issue.

As per the download page for 12.6 http://support.amd.com/us/gpudownload/windows/previous/12/Pages/radeon_linux.aspx?os=Linux%20x86&rev=12.6 one will see the release notes link http://www2.ati.com/relnotes/Catalyst_11.10_Linux_Installer.pdf which mentions the minimum system requirements:
"Minimum System Requirements
Before attempting to install the AMD Catalyst proprietary driver, the following software
must be installed:
 XOrg 6.9, 7.0, 7.1, 7.2, 7.3, 7.4, 7.5 or 7.6"

Now, if you want to make the argument because I have an xorg version not specifically mentioned, then the driver won't work, while this argument is also conjecture, then it won't work for _any_ card in Quantal, irrelevant to the card model:
apt-cache policy xorg
xorg:
  Installed: 1:7.7+1ubuntu4
  Candidate: 1:7.7+1ubuntu4
  Version table:
 *** 1:7.7+1ubuntu4 0
        500 http://archive.ubuntu.com/ubuntu/ quantal/main i386 Packages
        100 /var/lib/dpkg/status

Hence, we would have a bigger problem then just it doesn't work for me. It won't work for anyone in the Ubuntu Community using Quantal. Hence, this could be marked Importance Critical due to how this has "Has a moderate impact on a large portion of Ubuntu users" as per https://wiki.ubuntu.com/Bugs/Importance. As well, potential duplicates have already been filed prior to my bug report about this exact issue:
https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1068661

Next minimum requirement:
"Linux kernel 2.6 or above"

I have this:
uname -a
Linux moniker-PC 3.5.0-15-generic #23-Ubuntu SMP Mon Sep 24 20:37:59 UTC 2012 i686 i686 i686 GNU/Linux

Next minimum requirement:
"glibc version 2.2 or 2.3"
apt-cache policy libc6
libc6:
  Installed: 2.15-0ubuntu20
  Candidate: 2.15-0ubuntu20
  Version table:
 *** 2.15-0ubuntu20 0
        500 http://archive.ubuntu.com/ubuntu/ quantal/main i386 Packages
        100 /var/lib/dpkg/status

same point about no cards would work as noted above.

"POSIX Shared Memory (/dev/shm) support is required for 3D applications"
I'm not knowledgable enough to comment. However, same point about no cards would work as noted above.

Regarding the rest of your comments:
"Basically, either Ubuntu offered to install fglrx for you..."

I use Xubuntu and jockey/jockey-gtk doesn't work. Despite this, this is not required as I installed fglrx from the Ubuntu repositories as per the already attached install log https://launchpadlibrarian.net/120439929/fglrx-installer-log .

"(and the bug should be reassigned to ubuntu-drivers-common package because that shouldn't happen)..."

See above.

"...or you installed fglrx on your own accord (and the bug should be marked Invalid)."

This bug report is only focused on fglrx installed from the Ubuntu repository as previously mentioned.

However, in an attempt to WORKAROUND this problem, I uninstalled fglrx from the repos, reported this bug, and installed the driver downloaded directly from AMD, which also does not work. For more on the problem with the upstream release please see http://ati.cchtml.com/show_bug.cgi?id=625 .

In spite of all this, please do not comment further on this bug report unless asking for debugging information or providing a patch to fix this problem.

Thank you for your understanding.
