Bug description:
Trusty (and Utopic) SRU Request:
[Impact]
* Set higher priority of glxinfo's result then Xorg's log for
"Details" -> "Overview" -> "Graphics" info in Unity Control Center.
[Test Case]
* System with glxinfo installed (in mesa-utils) will show glxinfo's
result first for "Details" -> "Overview" -> "Graphics" info in Unity
Control Center.
* System without glxinfo will still parse Xorg's log for "Details"
-> "Overview" -> "Graphics" info in Unity Control Center.
[Regression Potential]
* Should be minimal, the info showed in glxinfo is more accurate.
[Original Bug Info]
In some of OEM's AMD platforms,
open "System setting"->"Details"->"Graphics" from control center,
find the Graphics Driver show VESA: XXXXXX strings ,
not as accurate as what glxinfo -l | grep "OpenGL renderer string"
shows.
The "VESA:XXXX" string displayed in "System Settings-->Details->Graphics" was because
unity-control-center will find the driver information via:
(1) parse /var/log/Xorg.0.log and find "VESA VBE OEM Product:" String
(2) if (1) is not found, parse the result of "glxinfo -l" and find
"OpenGL renderer string", and use this info as the string being shown.
There're some of AMD's fglrx driver will show "VESA VBE OEM Product:
XXXXX" string in /var/log/Xorg.0.log,
I've asked AMD and their reply is that the VESA BIOS message is traced
by VBEInit (libvbe.so) , which is out of fglrx’s control.
Curently this "VESA:XXXXX" string instead of the more accurate string
from glxinfo was being shown in the panel.
I think Use glxinfo's information (when available) first is more
accurate.
