Instalar driver ati no debian

Tive muitas dificuldades para instalar o driver da ati, mas aqui vai um resumo

Configure um dos repositórios abaixo no seu  /etc/apt/sources.list

You can download these packages with apt by adding one of the following lines to your /etc/apt/sources.list file:

deb     http://xoomer.virgilio.it/flavio.stanchina/debian-fglrx-modules/ /
deb      http://stanchina.sesse.net/debian-fglrx-modules/ / #thanks to Steinar

configure também o testing e o unstable para contrib e non-free

Altere o seu arquivo de configuração do X (serve para xorg.conf também)

Configure X

The driver package provides an automatic configuration tool called fglrxconfig. Just don't use it, OK? fglrxconfig is useful if you want a dual-head setup, but before you try that please make sure that a single-head setup works by editing your X server configuration file as outlined below. Also note that fglrxconfig will overwrite your existing X server configuration file!

Edit your /etc/X11/XF86Config-4:

Section "Module"
  ...
  # These modules are required for 3D acceleration
  Load "GLcore"
  Load "glx"
  Load "dri"
  ...
  # Load "extmod" but omit DGA extension 
  # (the DGA extension is broken in the fglrx driver)
  SubSection "extmod"
    Option "omit xfree86-dga" 
  EndSubSection
  ...
EndSection

Section "Device"
  Identifier "ATI"
  Driver     "fglrx" # this is the important bit

# If X refuses to use the screen resolution you asked for, 
# uncomment this; see "Bugs and Workarounds" for details.
  #Option "NoDDC"

# === Video Overlay for the Xv extension === 
  Option "VideoOverlay" "on"
# === OpenGL Overlay ===
# Note: When OpenGL Overlay is enabled, Video Overlay
#       will be disabled automatically
  Option "OpenGLOverlay" "off" 
# === Use internal AGP GART support? ===
# If OpenGL acceleration doesn't work, try using "yes" here
# and disable the kernel agpgart driver.
  Option "UseInternalAGPGART" "no"
 EndSection

Section "Screen"
  Identifier "your screen"
  Device     "ATI"
  Monitor    "your monitor"
  DefaultDepth 24
  SubSection "Display"
    Depth 24 
    Modes "1280x960" # this is only an example,
                     # use your preferred resolution here
  EndSubSection
EndSection

Section "DRI"
  Mode 0666
EndSection

Altere o /etc/fstab adicionando essa linha antes do /dev/proc

/dev/shm /dev/shm tmpfs defaults 0 0
