Re: [RESUELTO]: Driver "radeon" (era: imposible reducir el brillo de la pantalla)

[Eduardo Rios <eduriosg@yahoo.es>]

Puedo dar más info:

1. Si pruebo con este xorg.conf:

***
Section "Device"
    Identifier  "ATI"
    Driver      "radeon"
EndSection

Section "Screen"
    Identifier "Default Screen"
    DefaultDepth     24
EndSection

***

El Xorg.0.log termina con:

(EE) No devices detected


2. Si pruebo con:

***
Opción 1. Copia/pega simplificado del que te ha creado aticonfig

Section "Device"
     Identifier  "aticonfig-Device[0]-0"
     Driver      "radeon"
     BusID       "PCI:1:0:0"
EndSection

Section "Screen"
     Identifier "aticonfig-Screen[0]-0"
     Device     "aticonfig-Device[0]-0"
     Monitor    "aticonfig-Monitor[0]-0"
     DefaultDepth     24
     SubSection "Display"
         Viewport   0 0
         Depth     24
     EndSubSection
EndSection
***
