Xorg upgrade breaks acpid


Here is what happened:
In updating FC4 from Xorg 6.8.2 to 6.9, the acpid has somehow been damaged. On boot the daemon fails to initialize complaing /proc/acpi/event is busy or in use . When you log in, it complains "Can't access ACPI events in /var/run/acpid.socket!"

Nothing else was done, and I can guarentee this is somehow related to xorg, because on my last install of FC4 when I performed the same upgrade, it broke then as well. Xorg was upgraded by going to the xorg site, downloading the source, compiling it, and installing it. It compiled and installed without error.

I tried rpm -e acpid, and then yum installing it again, but that did not alleviate the issue.

After boot, I can "service acpid start" and it starts without error.

any thoughts on getting this to load properly on start?

this is one of those things where the developers all start arguing over whoos bug it is or whoos fault it is and who has to change what to make it work again.

one thing to try is to set acpid to start as early as possible and xorg to start as late as possible.
of course later they will no doubt begin to argue again.
if acpid is already running xorg opens acpid socket and all is happy
if xorg starts first xorg takes /proc/acpi/event and nobody else can read from it. At least i think thats whats going on.

of course xorg will argue its a kernel bug cause they have this new found status and bug bucks behind them and kernel maintainers will say
"It's not up to you to decide that a kernel interface is wrong, at least not
without the ACPI maintainer agreeing. " blah blah blah on and on.
i can't really figure out why they don't just test xorg and only release the ones that actually work...
oh yea that would make zero releases so far !
buggy code that breakes unrelated and vital software does not a great project make.

How do I go about that? I know nothing about ordering what starts when. Which file should I edit?

Well I tried changing S44acpid to S04acpid but that still occurs after xorg. I think I somehow need to tell inittab to start up the acpid daemon before xorg, does anyone know how to do that?

i don't use display managers so im so not the right person to help but
can you make xdm,kdm.gdm.wdm whichever you use start later ? like 99
otherwise you might have to boot to terminal login and use startx to fix it ?
i'm just not sure.
