 Posted: Thu Aug 13, 2025 4:37 pm Post subject: Laptop dead screen - Help ! |
 |
|
I dropped my laptop, and I won't be changing it soon since I broke my right hand, so I hooked up an external monitor to it temporarily.
Now, when I boot up, everything shows on thre external monitor, up to the login screen, except that at the login screen, everything shows on the dead screen.
Nothing can be seen on the dead screen, but I can still login by following the sound prompts. But even once I'm logged in, nothing is showing on the external monitor.
I am running the latest version of Ubuntu (9.04 I believe) and it is fully updated.
How do I make Gnome forget the laptop's screen and only use the external without seeing what I'm doing?
I've tried Ctrl-Alt-Backspace to no avail.
I've also tried Ctrl-Alt-F2-7 to try to get consoke access, but I still can't see anything.
Does anyone have any ideas, 'cause right now, I have to login to Vista to be able to use my laptop, because Vista gives me display options on both screens when I boot into it.
Any/All help is greatly appreciated as this is my main machine.

| Scrolling through Goooooogle, someone mentioned to try connecting the external monitor only after logging in, will try that tonight when I get home.

| Depending on the model, some will have a FN+Fx key to change it from internal display to external display. I know Dells have this, so that your OS would see the external monitor as the primary display instead of secondary.

I've never tried that set-up but recent xorg versions work 'just like that'
you may need to go into ubuntu's /etc/X11 and make an xorg.conf that specifies the external monitor as the monitor of choice?

Sadly, my FN keys aren't working.
I've never had the need for them, so I've never mapped them.

Really? That seems odd. They work on my Acer running Mandriva and I didn't have to map anything.

Maybe add an external keyboard along with the external monitor, and when you power up the laptop, immediately close the display down.... laptops are known to switch to external monitors when the display is closed.
My functions keys on my Asus EeePC 900A Netbook work fine with Ubuntu Netbook Remix 9.04.
Function keys for every laptop I've ever booted Linux on - all worked.
How'd you break your hand?

Usually is just that simple to take apart.
Just have to try to be sure you pivot the bezel if pivoting is the proper motion for that design. Some designs must pivot and will be damaged by being pulled straight out. Other designs are intended to be pulled straight out and are less prone to damage if pivoted. Gotta peek inside as you gently pry stuff apart (bright lights not really optional). Sometimes the bezel is NOT supposed to be taken off the back side, but the backside is to be pulled away from the bezel. Often, wireless antennas are strung up into the LCD/cover area.
So may possibilities, all could be resolved by a little cooperation on creating standards.

| And not just the wireless antennas.... microphones, cameras and little LED lights to illuminate the keyboard (IBM lappys have those). Who knows what else?
