Hi,

You want to use 2 monitors ? If not, just use VGA and all is ok. If not go to system settings menu and you can set if you want to use 2 monitors.


Don't ask, read : http://wiki.backbox.org
or just run sudo rm -rf /*

Yes I want to use 2 monitors. My X300 card has dvi and vga ports. I tried to go to display in the gui and there is no selection for extending the desktop. So I figured I would need to edit the xorg.conf which I can't find. I tried checking /etc/xorg.conf and its not there.

Yes I went to system settings/Display and I see both monitors but they are mirrored and there isn't an option to extend the desktop.

Hi,

What's the output of:
Code: [Select]
xrandrThat will tell us how your monitor(s) are detected and what resolutions are supported.

P.S. Try to run xrandr --auto, then go to Settings>Settings Manager >Display . Working with some cards.

Still getting the same result. When I go to system settings, Display. I see 2 monitors and my only options are "use this output"
Resolution
refresh rate
rotation= normal
reflection= none

Ok before we do something "hard" try with this tool.

Code: [Select]
sudo -i
apt-get install arandr
Then go to Settings>Arandr. If you see 2 monitors just set resolutions. If you don't see, click on Layout and add 2nd monitor.

After this ...more solutions possible, but try this easy way.

1.Arandr in Backbox menu :


2.Setting resolutions


3.Setting monitor orientation





P.S. Did you try to check "Use this output" for both monitors ?
P.S-2. Run in terminal xrandr --output VGA-0  --left-of DVI-0 ! If ok, we will add this to system boot ...i will say you how.

Thank you ZEROF.

No I haven't run it yet. It would really help if I can extend the destkop so I can work in both windows.

Nice, now you need to set startup ...Go to Settings>Settings Manager > Session and Startup >Application Startup.

1.Clic on Add
2.New wilndow will pop-up
3.You need to set 3 fields, check photo



In command field set xrandr --output DVI-0 --auto .

Do I need to put in the command field to turn off S-video each time?

xrandr --output S-video --off

I would say it's stupid question. When restart my system I have do few things listed below.

1) fire up xrandr which is given.
2) move the DVI input on right side of xrandr box but when I hit apply I get the follow error. "xrandr: cannot find crtc for output DVI-0"
3) I open terminal and disable s-video with this command xrandr --output S-video --off.
4) go back to xrandr and select apply and now extended desktop is turned on.

The problem I'm facing is how do I disable S-video on startup. I mean I can disable S-video port in /etc/X11/xorg.conf but I can't ever track it in Ubuntu.

Hi,

Ok, then do the same add this command to Session and Startup. That need to look something like :

xrandr --output S-video --off
xrandr --output DVI-0 --auto

Or try this : http://www.anonimus.re.rs/6521
