Black Screen After Dual Monitor

[tuan_b918]

Hello all,

I have an Intel Corporation Mobile 945GM chipset. As I was playing around, trying to figure out how to get my dual monitor to work. The Mirror Screen was working fine, but then I uncheck the mirror screen option, both my laptop and my secondary monitor black out. I can only see the mouse, and it cans move on both screen. Please help.

Here is my xorg.conf:

HI there. I am familiar with that chipset, as I once had it in my Dell branded desktop. Try again to mirror, then go through the process again, and have each monitor be a clone of the other; go through the process again, but this time have the primary monitor be to the left, or be to the right as you'd want to have it. I've had to do that for the nVidia system in my current desktop. I run a Dell XPS8100 desktop now in which I have to do that. Something else you may want to do, is disconnect the monitors, then connect up the primary monitor, then the secondary. Sometimes video cards need to have this done to reset them. SO if you also had to do this, then repeat the original steps. If you get the same symptoms, come back to the forum here, and we'll see what we can do. Perhaps there's some others that can also offer assistance.

Dual monitors is like having two computers.

I have this problem too. Was there ever a solution for it?

Thanks!

Hi there. Can you tell me the procedure of connecting the two monitors please ? Also, have you just connected one monitor at a time ? Perhaps what worked for me may just well work for you too
