Topic: [SOLVED]extended desktop

Hi, i've got my 32" LCD connected to my pc with hdcable and with windows i can extend my desktop area to the TV and see a movie on the tv while using my computer screen to surf on the web or chat in msn.
I would like to know if there is possible to do the same thing on #!. If so, can someone tell how?

thanks

ok so i've found some info on that already on the forum but i just followed it and it didn't worked for me.

i type this:
xrandr --output DVI-0 --mode 1280x720 --right-of DVI-1
and got this:
xrandr: screen cannot be larger than 1680x1600 (desired size 2960x1050)

how can i make it work?

Re: [SOLVED]extended desktop

here is the line I use for mine that works:
xrandr --output LVDS1 --primary --mode 1366x768 --pos 0x0 --output HDMI1 --mode 1680x1050 --pos 1367x0 --right-of LVDS1
you may just need to set the mode and position for DVI-1, it may be a limitation of your video driver in linux though.

I say never be complete, I say stop being perfect, I say lets evolve, let the chips fall where they may.

Re: [SOLVED]extended desktop

This is what I have in my xorg.conf in Section "Screen":

        SubSection "Display"
                Virtual 2048 2048
        EndSubSection

My netbook's graphics chip is limited to 2048x2048, so I'm limited to --above or --below.  But with your hardware you might be able to do

        SubSection "Display"
                Virtual 2960 1050
        EndSubSection

and get down with your --right-of.

while ( ! ( succeed = try() ) );

Re: [SOLVED]extended desktop

Daniel,

If you're trying to use both screens at the same time you'll have to consider the total resolution, the sum of both screens. So, if your driver is limited to 2048x2048 (h x v) you'll have to "fit" both screens in there or disable one screen and use the second at a time.

This wiki explains it very well.

Cumprimentos. Regards.
