http://askubuntu.com – I'm currently using a Laptop running Ubuntu 12.04. When I'm at work I plug in a monitor, mouse and keyboard. Then I close my laptops screen and use it as a normal pc. Everytime I plug it in and plug it out, I have to change my system settings, because normally my laptop would suspend to RAM, when I close its screen. Also I have to change where my graphics card should display my desktop. Is there any way to execute some script when an external monitor or usb-device is plugged in or out? If yes, is there any way to change my system settings by a shell script? If not, is there any other way to d (HowTos)

Stories similar to Change system settings depending on whether a monitor is plugged in

I was just playing with hardware on Ubuntu the other day, just by adding a second monitor (acer) to my laptop (dell vostro 1000). All went fine, some display settings worked out, other didn't (laptop could only handle the 1280x720 60hz setting, the acer screen could handle other screen resolutions and refreshrates).

Hi, guys.I am using Arch on my laptop. When I am at home, I use my laptop plugged in a 23" flat screen via HDMI port.But when I use it plugged in to the external monitor, the system boots showing the image only on the external screen, like I want.

I have a macbook air with intel graphics, yesterday I disabled the laptop screen while I used an external screen and today whenever I plug it in the laptop screen goes off and the external monitor does not come on.

So, I start Ubuntu on my laptop, then I plug in my external monitor and I go to preferences and click on display to change the screen from laptop io the external one, just as I click on display, the laptop screen goes dark, only I see the mouse pointer, and nothing on the external screen. If I turn on the computer with the external display plugged in, everything works fine.

I'm having some issues connecting an external monitor to my laptop using the vga cable. If I plug the cable in while the system is running, the system grinds to a near halt. If I attempt to use Preferences>Display to detect the additional display, the app locks up and I am forced to close it manually.

I've recently installed 11.2 and find that today docking the laptop for the first time doesn't automatically enable the external monitor. I was expecting the external monitor to be enabled and the laptop screen to be disabled as the lid is closed anyway, i.e. the video to be switched to the external monitor when docked.

I have just upgraded from 12.04 to 12.10 (was actually a fresh install with the home partition kept and '/' wiped).

I am attempting to make my laptop monitor (Hp dv6) and my Samsung BX2450 monitor work together successfully without the nvidia package (12.04 and down needed these just to detect the extra model).

I am met with the following inconsistencies and don't really know how to go about fin

Opensuse 11.3 KDE 4.4.4 ati radeon 4330 with default driver - nouveau (although laptop has hybrid graphics i was eventually forced to switch intel off, because automatic switching dont work with X and both systems are consuming power - but this is another story)

Ill describe 2 use cases how it should work:

So, my problem is that when I turn on my laptop and it starts booting Ubuntu, the monitor goes on and off a few times.

When it reaches the state where the system is loaded and should start working, the monitor on my laptop is black, nothing on it, not sure if it's turned on even.

After that, I plug in an external monitor, and my laptop monitor starts working.
