[darknight]

I'm having problems finding the correct drivers and figure out how to extend my desktop. Here is my video configuration.  It seems like it's not identifying the DVI part of graphics card.

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.

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 Expand

xrandr
That 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.

Ok I will try that see if it works. Thank you

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

[ZEROF]

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

Code Select Expand

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.

getting the follow error "xrandr: cannot find crtc for output DVI-0"

[darknight]

I got it thx for your help.

xrandr --output DVI-0 --auto

[ZEROF]

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 .

[darknight]

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

xrandr --output S-video --off

[ZEROF]

If you try you will see, no ? I like to help but don't ask stupid question bro.

Cheers!

[darknight]

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
