Package: xserver-xorg
Version: 6.9.0.dfsg.1-1
Severity: normal

Hello,

I just noticed that Xorg uses ACPI's /proc/acpi/event. Now, when acpid
is running Xorg is smart enough to read from its socket instead, and
when you, brave user, stop acpid: kaboom!
Xorg uses all my CPU leaving no option than restarting it.

Disabling PM management (Option "NoPM") obviously helps and also fixes
xorg stealing /proc/acpi/event.

BTW: I'm stripping some of the package info below as they're not much of
use.

Looks like X behaves properly on acpid going away and coming back.
I'm closing the bug.
