So the latest kernel powers down properly, but only if you don't start X? With older kernels it would not power down even without X?

Although I'm running the new, clean table, the IASL says >everytime something about 36 optimizations. Actually, I'd prefer that you not modify your DSDT at all. Verify that you have the latest BIOS from the vendor, and if Windows can deal with it and Linux can not, then it is a Linux bug that we need to know about -- not something you want to hide by modifying the firmware. So check your BIOS. Check your video driver version, and the version of X in general. Yes, the issue is probably an interaction with ACPI, but is quite possibly a firmware or video software platform-specific issue. -Len - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
