Hence my confusion, llvmpipe (LLVM 5.0, 128 bits) with the radeon driver
is reported. And CAPE VERDE with the ati driver. Why would the wrong
driver show proper input with glxinfo?. Either way still shows wrong
graphics card all together.

Title:
AMD r7 250 wrong detection
Status in mesa package in Ubuntu:
New
Status in xorg package in Ubuntu:

Bug description:
My AMD R7 250 GPU is being wrongly detected in Ubuntu as a Radeon HD
8830M. This results in the wrong detection of drivers. The result is a
wrongly installed driver and very poor performance. This bug has been
affecting me since Ubuntu 16.10, and still affects me in Ubuntu 17.10.
brad@brad-ubuntu:~$ lspci | grep 'VGA compatible controller'
02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Venus LE [Radeon HD 8830M] (rev 87)

Ubuntu installs by autodetection: xserver-xorg-video-ati. The proper
driver is, xserver-xorg-video-radeon.
However even after proper installation of the new driver. Ubuntu still
reports that I am using a mobile graphics card, instead of a desktop
graphics card.
Ubuntu reports: llvmpipe (LLVM 5.0, 128 bits) with the radeon driver. And
CAPE VERDE with the ati driver. Its a "OLAND" or "southern island" card.
