xorg.conf has been phased out for many releases now. The support is there for cases when automatic configuration doesn't work. So my question is: have you tried without any xorg.conf? Maybe use xrandr to get the correct resolution working? Something like this might work: $ xrandr --output <HDMI display> --mode <resolution> \ --output <your regular display> --mode <resolution> You can get the allowed values with "xrandr -q". Hope this helps. -- Suvayu Open source is the future. It sets us free.

None. The key in both KDE and Gnome is to UNcheck unify displays.

Have you tried booting with a regular monitor? Are you booting to the multi-user.target (runlevel 3) or graphical.target (runlevel 5)? What do you mean by filesystem mounted through NFS? I presume you mean its only the home directory. If so that should be irrelevant here.

also ,when i try to run "X" command i am getting an error: "vgaarb:this pci device is not a vga device"

What graphics hardware do you have? The following command should help you figure out. $ lspci | grep -i vga Usually people don't call X directly, a script is called instead. Something like startx, startxfce4. startkde ... (depending on desktop environment or window manager). Any particular reason you are not using that? If there is no X session, I would expect xrandr to fail. So I think you first need to sort out why you have problem running the X server. Maybe you don't have appropriate graphics drivers (possible if your graphics card is very new or extremely old). Hope this helps. -- Suvayu Open source is the future. It sets us free.

Hi Lokesh, A small comment before we get on to your problem. Please do not top post, it makes it difficult to follow the thread.

Some important questions might be: 1. How many and what displays were connected to your machine when you tried this? 2. Were you connected remotely over ssh? Those are the two things that came up. In short more information is always good. -- Suvayu Open source is the future. It sets us free. --

You are not giving any details about your setup. Some important questions might be: 1. How many and what displays were connected to your machine when you tried this? 2.
