http://forums.fedoraforum.org – Hello, I have an Toshiba Tecra R950 with F17 x86_64. At work I have it connected to an exteranl LCD monitor trhough the Display Port and I have NO problem with this configuration (dual monitor, closing the laptop and using only the external etc.). I also connect it to a USB keyboard and mouse. This laptop comes with a Radeon HD 7570M and I am using the Xorg radeon driver. Ironically, when I boot without external monitor (using just the LCD/LED screen) the GNOME Shell crashes on login with the "Something have went wrong" message. I do not see any relevant message either in s (HowTos)

Stories similar to Gnome Shell only works when using external monitor

If I have my external monitor attached to DVI I can just see the background image on the laptop and the external monitor stays black, no gdm login or anything.

All works fine until I move the mouse cursor on the monitor to either the bottom of the screen or to the right of the screen. It then disappears from the monitor and re-appears onto my laptop screen. There is no way I can then get control back onto the monitor screen.

Hello!

So I have yet another dual monitor setup question.

I am using ubuntu 12.10, with gnome classic (not unity)

I have a laptop with my LCD screen (duh), and an external monitor that is connected most of the time, but not always, and sometimes I have to disconnect it while working to use it for other things.

Problem is: When the external monitor is connected, I use that as my main display, a

I've installed Ubuntu 12.04 on my Toshiba Tecra A8 laptop. It has Intel 945GM graphics.

All my hardware components work fine except for the external monitor. When I plug in the monitor cable to the external VGA port, Ubuntu detects it, but the screen goes black and I don't get anything displayed – both on the LCD and the external monitor.

How can I solve this?

I'd like to disable my laptop monitor at startup (when an external monitor is connected), but make it available in X.By default, my boot looks like :* Grub2 displays only on my external monitor (at maximum resolution)* Kernel displays only on my external monitor (maximum resolution)* udev (I think) is started and turns on my laptop screen.

I have a msi A6000 laptop with a nvidia GeForce 8200m. I have installed the recommended proprietary driver for the graphics card.

The problem occurs when I try to use my Gateway FPD1810 monitor that I have connected to my laptop. I go into the X server, enable the monitor, click "Save to X configuration file", and get this message:

My laptop is the Toshiba satellite c850-F31Q (with these specs:http://www.laptopdirect.co.za/laptop_specifications.php?laptop=59683)(AMD Radeon graphics card).

It is running Linux-Ubuntu-gnome 3 (and Windows 7; dual boot)

Urgently need to know how to connect it via VGA to -

External LG monitor (works great in Windows).

Please could you help.

Dear All..

Greetings..

I've been trying to connect my external monitor to the laptop in Gnome3 since 1 week now, and nothing seem to work..! The second I connect the external monitor, my laptop monitor flirts twice, and then:

Oh no!

I use an ATI Mobility Radeon HD 6370 with proprietary drivers v11.8 in Ubuntu 11.10 64 bit and I can't get it to detect an external monitor through HDMI. Not with the Catalyst software nor with the "Displays" utility. I just want to set up a simple and straight forward clone display configuration to see my laptop output on my HD TV monitor.
