Fedora 12 on Dell D400 freezes when laptop lid closed

[grayswander]

)I have Fedora 12 installed on Dell D400 laptop. I ran into the following very frustrating bug: the computer totally freezes when laptop lid gets closed.
Steps to reproduce:
1) Install Fedora 12 on Dell D400
2) Update, if you want :-)
3) Start it up, doesn't matter to runlevel 3 or 5
4) Close laptop lid
5) Computer hangs, freezes, gets stuck. :-(
6) Hard reset the computer.

After a while I've discovered that haldaemon is responsible. Stopping the haldaemon allows to close the lid without reboot, but is not a good solution in the long run.

Finally, I've found a solution:

echo "1" > /proc/acpi/video/VID/DOS 
echo "1" > /proc/acpi/video/VID2/DOS

How to make it permanent (copy and paste in terminal as root):

cat >> /etc/rc.local <<ENDL
# Work around HAL bug with laptop lid closed:
echo "1" > /proc/acpi/video/VID/DOS 
echo "1" > /proc/acpi/video/VID2/DOS
ENDL

Hope this helps someone.

So how did you come across this information?
I have a hibernate problem that I'm trying to diagnose. The symptoms are not the same as yours, but the solution may be found if I know more about HAL.
This post of mine describes my hardware and symptoms:

And, a couple days ago it looked like It was solved, but I discovered after plugging the power in that I was back to square one. I haven't updated that post to reflect the regression, I've been too depressed.

This was not the case.
My problem was not connected to Xorg at all. The system got frozen the moment the lid got closed. The "known bug" addresses turning display on when the lid is opened.

I don't really remember. I've picked it up as wild guess on some kernel development forum.


Now I have much more weird problem:
The system gets frozen on second time I close the lid.
