xfce can't detect second display
I have a newly installed xubuntu 12.04 distro on my intel netbook and I'm trying to get the display on my tv through a VGA cable. My friends windows machine works fine but I can't detect the tv through the Display settings or through ARandR
Here is the output from xrandr Quote:

Try to activate the second screen with
Code:
xrandr --output VGA1 --auto |
Some progress, thank you very much. Now the Display settings recognize the tv but the tv still isn't displaying anything
xrandr output again. Quote:

You need to go into your monitors applet in your System settings and tell the second output what to do.

The only other display related settings i can find are in the screenshot below. I tried playing around with it but couldn't get anything to change.
If this is the correct area what am I supposed to change the values to? If not where else am I supposed to go or what commands can I run? https://plus.google.com/photos/10201...PqV8rSttobXlgE |
I resolved it to me using xorg and xinerama, but I'm not using a TV but two different vga cards, intel and nvidia
Code:
Section "ServerLayout" |
I'm sorry I don't follow, am I supposed to put this into a text file somewhere?
|
You should have a Display entry under settings on your main menu? That should let you enable the second display.
|
In your menu under settings - monitors.

Thanks for putting up with me guys but I can't find any other display options, we're talking about xubuntu xfce right? In this gallery are screenshots of what's in my main menu and my settings page.

Is the TV set to use the correct input? Just a thought as I thought I had a problem not long ago until I set the input on my monitor.
|
You're missing some applets, my system has many more options under settings. How did you install Xfce, and did you do a full install? Of course, it could be because I have Gnome and KDE installed as well.
|
The tv is set up correctly.
Oh okay, it's a fresh install of Xubuntu 12.04 which only comes with xfce. I was hoping there would be a way to do it within xfce but do I need to install KDE or gnome? |
Where you're ticked "use this output" is that the TV you have ticked the box for? If so then XFCE is seeing it as an output and is sending a signal to the cable for it. Why it's not seeing that signal I'm not sure, which is why I asked whether you were sure the TV was set up correctly.
If that's not the TV that you've ticked "user this output" for does that mean you already have a monitor plugged in and you're trying to connect the TV too? |
