Getting Dual Monitors to Work

[Guest]

I've installed kubuntu for the first time (although I have been using linux for a few years).

I'm trying to get dual monitor support (extended monitor and cloning) to work properly on my laptop, but don't seem to be having any luck (nothing works).

My laptop is a toshiba a50, my graphics card is identified as follows:
Code:

00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)
00:02.1 Display controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)

My xorg.conf currently looks like this:
Code:

Section "Monitor"
  Identifier  "Configured Monitor"
EndSection

Section "Screen"
  Identifier  "Default Screen"
  Monitor    "Configured Monitor"
  Device    "Configured Video Device"
EndSection

Section "Device"
  Identifier  "Configured Video Device"
EndSection

Section "ServerFlags"
  Option  "DontZap"  "False"
EndSection

In the display option under system settings, both monitors are detected: the laptops LCD is showing up as LVDS and the external as VGA (I'm unable to try TV-out at this point).

I can play around with the options for both monitors (resolution and refresh rate), but cannot get the external monitor to go at all (yes, it does work fine). If I click "identify outputs", then I see that both LVDS and VGA appear on the laptop's monitor! In the green box on the right I can see "VGA" underneath LVDS.

Ultimately I'd like to have an extended monitor, using the secondary one for presentations etc. If I could even get cloning to work, that would be a start...

Thanks for your help.

Re: Getting Dual Monitors to Work

the xrandr command is what I use for dual head. here's an example command I use to set up my laptop's 1280x800 display, and an external 1280x1024 projector:

xrandr --output LVDS --mode 1280x800 --pos 0x0 --output VGA --mode 1280x1024 --pos 1280x0

Re: Getting Dual Monitors to Work

I've tried your example (modifying it to suit my resolutions), but I still can't see anything on the second monitor (it still doesn't seem to be getting any signal).

I added a Virtual line to my xorg so that I could get your command to work. Now windows open up on the second monitor, but of course I can't see anything there, so I have to move them back across to the first monitor.

I know the VGA output works, because if I boot the computer cold with the monitor plugged in, it uses that instead of the internal display.
