xorg.conf erstellen

sudo nvidia-xconfig

sudo init 6

edid.bin erstellen

Nachdem das System neu gestartet wurde kann unter der grafischen Oberfläche das NVIDIA Konfigurationsmenü aufgerufen werden.

• Dash-Startseite -> Suchen -> Terminal

sudo nvidia-settings

GPU-0 (GeForce GT 630) -> DFP-1 (DENON, Ltd. DENON-AVAMP) -> Acquire EDID...

Die erstellte Datei unter folgendem Pfad ablegen:

/etc/X11/edid.bin

Falls Ihr die edid.bin nicht direkt unter /etc/X11 abspeichern könnt speichert diese vorerst unter /tmp und kopiert diese dann manuell nach /etc/X11:

sudo cp /tmp/edid.bin /etc/X11

xorg.conf anpassen

Gegebenfalls müsst Ihr eure xorg.conf auf eure Grafikkarte und TV anpassen. Anbei findet Ihr meine xorg.conf.

Zu finden unter:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_orig
sudo vi /etc/X11/xorg.conf

Prüfen ob der Bildschirm richtig angesteuert wird

Es ist wichtig das euer LCD Bildschirm mit 50 Hz angesteuert wird. Es kann folgendermaßen geprüft werden:

DISPLAY=:0 nvidia-settings --query RefreshRate

  Attribute 'RefreshRate' (vdr:0[dpy:2]): 50,00 Hz.
    'RefreshRate' is an integer attribute.
    'RefreshRate' is a read-only attribute.
    'RefreshRate' is display device specific.
    'RefreshRate' can use the following target types: X Screen, GPU, Display Device.

Toneinstellungen

Der Ton wird über HDMI der Grafikkarte ausgegeben.

sudo cp /etc/pulse/client.conf /etc/pulse/client.conf_orig
sudo vi /etc/pulse/client.conf

Ändern von:

;autospawn = yes

Abändern in:

autospawn = no
