I have an hp nx7400 notebook with intel 945gma. The lid switch normally toggles (using acpi video module) internal display and external display.
It works like a charm, unless using mergedfb. I have not tried with dual screen or dual screen + xinerama because I was affected by the bug fixed (probably, I've not tested it) by 1.7.4 version of the driver.
Using mergedfb, if I press the lid switch or close the screen, the display gets corrupted and I have to reinit the card switching to a virtual console and returning back to X.

Is there a way to disable the switching behaviour of the acpi code? I was able to disable completely the switch unloading the acpi video module, but it's not the right way....
Please send me acpidump output , let me check how does acpi video extension get
supported on hp nx7400.
If it support _DOS, please just try " echo 0 > /proc/acpi/video/*/DOS "
Thanks,
