    red flashing when playing video

    Hey,

    When I try to play video (or run the video part of the test in "Hardware Testing"), I get red flashing on the screen, either being the whole screen flashing or flashing in blocks. I a using a GeForce 9600M GT.

    Any ideas? I have tried reinstalling drivers, as well as video players / codecs and nothing seems to have any affect. Sometimes I think it has stopped, then the next time I reboot it will start doing it again. I don't have the problem in Windows so I assume its not a hardware issue.

    Cheers,

    Hi and Welcome !

    Execute this
    Code:
    sudo lspci | grep -i  vga
    Post output here.
    Post the contents of /etc/X11/xorg.conf file here.
    It is amazing what you can accomplish if you do not care who gets the credit.

    Thanks for the welcome and the quick reply! I've only been using linux a few months, but definitely enjoying the change, albeit the minor growing pains

    Here is the lspci output:
    01:00.0 VGA compatible controller: nVidia Corporation GeForce 9600M GT (rev a1)

    Here is the data from X11:
    # xorg.conf (X.Org X Window System server configuration file)
    #
    # This file was generated by dexconf, the Debian X Configuration tool, using
    # values from the debconf database.
    #
    # Edit this file with caution, and see the xorg.conf manual page.
    # (Type "man xorg.conf" at the shell prompt.)
    #
    # This file is automatically updated on xserver-xorg package upgrades *only*
    # if it has not been modified since the last upgrade of the xserver-xorg
    # package.
    #
    # Note that some configuration settings that could be done previously
    # in this file, now are automatically configured by the server and settings
    # here are ignored.
    #
    # If you have edited this file but would like it to be automatically updated
    # again, run the following command:
    # sudo dpkg-reconfigure -phigh xserver-xorg

    Section "Monitor"
    Identifier "Configured Monitor"
    EndSection

    Section "Screen"
    Identifier "Default Screen"
    Monitor "Configured Monitor"
    Device "Configured Video Device"
    DefaultDepth 24
    EndSection

    Section "Module"
    Load "glx"
    EndSection

    Section "Device"
    Identifier "Configured Video Device"
    Driver "nvidia"
    Option "NoLogo" "True"
    EndSection


    Cheers for the help!

    Edit xorg.conf file :
    Code:

EndSection

Identifier "Configured Video Device"
Driver "nvidia"
Option "NoLogo" "True"
EndSection

Section "Monitor"
	Identifier	"Configured Monitor"
	Option		"DPMS"
	HorizSync	30-71
	VertRefresh	50-160
EndSection

Section "Screen"

    Hi, thanks for the help, but now my screen is permanently in 1024x768, when it is meant to be in 1440x900, basically it looks like ****! Every time I reboot it resets to 1024x768. What should I change?

    Cheers

    Add 1440x900 resolution in Modes line.

    Code:
    		Modes		"1440x900" "1280x1024" "1024x768"
