    Widescreen Problems- Intel

    I have a 23 inch samsung hdtv that I use as a monitor. Its native resolution is 1280x720 and it runs perfectly in XP. My graphics are Intel Integrated. I installed Suse 10.2 yesterday. When going through the install, it recognized my monitor but had the resolution set to 1280x768. I tried to change it but it didnt have the native res I needed. I installed anyway and on restart my monitor said video mode not supported.

    So right now I have it running on an old CRT. Unfortunately, it is at 1280x768 and has a refresh rate of 75 (which is too high for my lcd) and I am unable to change it. I want to be able to run Suse at 1280x720 if at all possible, but I need some help. Any ideas?

    Hi Wilund,

    Welcome to LinuxForums.

    edit xorg.conf file and set correct HorizSync, VertiRefresh rates and Resolutions.
    log in as root, open terminal/konsole and create a backup copy of xorg.conf file
    Code:
    cd /etc/X11
cp xorg.conf xorg.conf.orig
    open xorg.conf in nano editor
    Code:
    nano xorg.conf
    edit and save file. shutdown, plug-in hdtv and reboot.
    It is amazing what you can accomplish if you do not care who gets the credit.

    Hello and thanks for the warm welcome.
    I am at school right now but I have a couple questions. I'm somewhat farmiliar with the xorg.conf file, but isn't there some kind of modeline thing that I need to add to it as well?

    Also, how do I figure out the exact HorizSync and VertiRefresh settings that will work for my hdtv?

    mode lines are Resolutions. something like this
    Code:
    Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"
	Monitor    "Monitor0"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
		Modes    "1280x1024" "1280x720" "1024x768" "800x600" "640x480"
	EndSubSection
EndSection

    no idea. these are Generic Rates
    Code:
    Section "Monitor"
	Identifier   "Monitor0"
	ModelName    "xxxxx"
	HorizSync    30.0 - 60.0
	VertRefresh  50.0 - 85.0
	Option	    "dpms"
EndSection
