xrandr is showing the wrong device names

[Removed by request]

I'm using Ubuntu 13.04 dev with x11-xserver-utils 7.7~3ubuntu2. "lspci | grep 'ATI Wrestler'" is showing me the following:

00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Wrestler [Radeon HD 6320]
00:01.1 Audio device: Advanced Micro Devices [AMD] nee ATI Wrestler HDMI Audio [Radeon HD 6250/6310]

It is an ATI chip with a HDMI port. xrandr is showing the following:

Screen 0: minimum 320 x 200, current 1366 x 768, maximum 1600 x 1600
LVDS connected 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
   1366x768 60.0*+
   1360x768 60.0
   1280x768 60.0
   1280x720 60.0
   1024x768 60.0
   1024x600 60.0
   800x600 60.0
   800x480 60.0
   640x480 60.0
DFP1 disconnected (normal left inverted right x axis y axis)
CRT1 disconnected (normal left inverted right x axis y axis)

DFP1 is my HDMI port but I'm wondering why it isn't showed as HDMI1 or something else. I'm also wondering why there is CRT1 because I haven't connected another monitor on my laptop.

My monitor is on Svga port. [moniteur sur prise SVGA]
I have Background Color and mouse cursor (cross) [Pourtant il y a la couleur de fond d'écran et le curseur de la souris]
Buti can't drop application window on [je n'arrive pas à y déplacer les fenêtres des applications]

Je ne sais si c'est un soucis randx ou lié avec Unity
