New versions of xorg uses either acpid or opens /proc/acpi/event during startup in order to get access to ACPI events. With distributions that use X during boot (like Red Hat's rhgb) this causes problems since /proc/acpi/event will be opened by the X server when acpid starts. Something needs to be done about this. The two current suggestions are: * Make sure that acpid is started before any X server. * Have a configuration option for X that disables the ACPI integration. Any graphical boots would use this configuration to avoid problems. Red Hat's bugzilla entry: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=169766
Reassigning to Alan, since he checked in the ACPI code and made it the default. Kevin did checkin a small fix, so he might have some ideas about this as well. Adding him to Cc.
Created attachment 3842 [details] [review] add option to disable acpi This should allow those who do not want it enabled to disable it.
Thanks. Does this include an option for xorg.conf?
No. Purely commandline.
Actually, you could use the NoPM option for xorg.conf, although that would disable APM as well.
Thanks for the "NoPM" hint. This helps a lot.
