[Bug 1617849] Re: latest system update broke fglrx video drivers, so no more 3d video acceleration

[Rob]

I'm afraid I cannot include the output requested, because I have since
replaced the 14.04 LTS installation that this bug affected with a 16.04
LTS install.

I had been under the mistaken understanding that Catalyst drivers /
fglrx were necessary for my use case, which is why I had installed 14.04
LTS. I have since learned that the Mesa 10.1 version in the 14.04 LTS
release is is about 2 years old, and the OpenGL drivers were not quite
usable. However the OpenGL driver version in 16.04 LTS, which I have
since installed, is perfectly suitable for my use case, and appears to
outperform fglrx.

I suspect that the 14.04 LTS upgrade that deprecated fglrx was related
to fglrx's incompatibility with an X and/or kernel update. While 14.04's
OpenGL drivers are not suitable for my video card, those in 16.04 more
than suffice.

In other words, the fix to this 'bug' seemed to be to update/upgrade to
Ubuntu 16.04.

Title:
  latest system update broke fglrx video drivers, so no more 3d video
  acceleration

Status in ubuntu-release-upgrader package in Ubuntu:
  Incomplete

Bug description:
  System is 14.04 LTS.

  As a reminder, AMD fglrx drivers (formerly Catalyst) are deprecated on
  16.04 LTS. The current suggested workaround for people who need fglrx
  drivers is "use 14.04 LTS".

  I have my system set to weekly updates. The most recent system update
  reverted my system back to the open source driver (xserver-xorg-video-
  ati).

  The update system still seems to identify fglrx as available. Fglrx
  and fglrx-updates both appear as options in the System > ... >
  Additional Drivers dialog. However selecting them and attempting to
  apply the change, the system will churn a bit then just reselect the
  open drivers option, without any dialog or error message.

  The open video drivers don't enable 3d hardware acceleration, which is
  unacceptable for my use case.
