(Get the code!)
Hi,
in the last couple of days I've tried all the options I could think off:
- 3D enabled (running Compiz and GL screensavers) or disabled (switching to MESA software implementation)
- DRI/GLX on/off
- DDC/DPMS on/off
- ACPI/HAL on/off
- xorg.conf's NoPM
- CheckDevices on/off
I might have missed some weird combinations of all the above, but I tested a lot... Nothing there prevented my system from hanging on lid close :-(
Peter's tst3 hasn't been very helpful in pinpointing the issue, as I didn't get any messages in the Xorg.0.log file.
Looking for a way to "lie" to X and fake an external monitor, Peter then pointed me to this patch by Raúl Sánchez Siles: https:/
which forces the driver to detect an external monitor with the (undocumented) option
Option "ForceEnablePipeA" "true"
Using this patched driver and option, I get a better behaviour: my system happily blanks the monitor on lid closing, but does not hang. Hitting the keyboard or moving the mouse unblanks the screen correctly.
However, I have a new problem: now my system locks on lid *opening*.
This time, disabling ACPI (sudo /etc/init.d/acpid stop) works around the problem (rmmod video, disabling only the acpid socket, or using NoPM in xorg.conf are not enough): opening the lid has no effect, the monitor is still blanked but the system doest not hang. Keyboard/mouse do not unblank the screen, either, but switching to a text console and back to X works.
I've put a .deb package of the patched driver online if anyone is interested in giving it a try (for the sourced just look into the same directory):
