laptop with external screen wont run laptop screen


Hi,
I have a laptop that has been connected to an external screen ever since i installed linux on it but i now wish to use it as a proper laptop but i when i run it without the external screen, the laptop screen goes blank after the initial boot splash screen. Is there a way to fix this?

Any help is much appreciated.

Cheers.

You don't say what model laptop it is. I had a similar problem with a friends Dell. I had to reset the video settings in the bios via the external monitor.

Hi,
And thanks or the reply. The Laptop is an AsusZ9100L. The bios was set to boot the external screen but i have reset this to boot to the laptop display (LFP). I also renamed the xorg.conf file to force the system to reconfigure the graphics and now it boots into the operating system (linux mint) but then locks up. So i assume from this that it is a graphics configuration issue. What do you think?

Thanks again for any help.

Cheers.

Hi,

so that we can try to understand what is happening please post your x log file. You should be able to find it at:
Code:
/var/log/Xorg.0.log

From your log file
Code:
(EE) Failed to load module "i810" (module does not exist, 0)
From the log it seems to be falling back to the vesa driver. However that is not the main problem (vesa should work).
Do you have the xserver-xorg-video-intel package installed? Also you might want to have a look at the i810switch package.

I suspect that your xorg.conf is to blame. So please post your /etc/X11/xorg.conf
It is also worth trying to run X with out the config file.
Code:
mv /etc/X11/xorg.conf /etc/X11/xorg.conf.back
Cheers,

Evo2.

Hi and thanks for the reply,
I had actually already renamed the xorg.conf file in an attempt to force the graphics to reconfigure itself - see previous reply and this did make an improvement but still cant get into the OS properly before it locks up and have turn off. There is currently no xorg.conf file.

Currently i access the system by using the install version of mint 9 on USB drive.

Copy of original xorg.conf (now xorg.conf.bak):

Code:
Section "Device"
	Identifier	"Configured Video Device"
	Driver		"vesa"
EndSection

Section "Monitor"
	Identifier	"Configured Monitor"
EndSection

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

Just to make sure we are on the same page, this is my understanding of your current situation.

- You now have no /etc/X11/xorg.conf (good)
- When you boot the os it "locks" up and you then turn the machine off using the power button (bad)


Do you know what is causing the lock up? Is it X trying to start? If so, you can disable X from automatically starting at boot.

To do this boot up the machine using your live usb image, mount your hard drive and move the X startup script:

Code:
mv /etc/rc2.d/S01gdm /etc/rc2.d/K01gdm
The above assumes that mint has inherited the standard sysv style init that Debian uses. You will probably need to modify the above command slightly.

Anyway once you've done this you should be able to boot up your system as normal with the exception that X will not be started. Then you can have a poke around and try to understand the root of the problem is.

Cheers,

Evo2.
