The title might be a little long so let me explain it here. This is in relation to my post on Ubuntu hanging during boot with nVidia FX 5200. A brief history: I tried to install and boot Ubuntu (all releases till date) with my card, and ACPI settings turned on. The LiveCD boot and the boot after installation, both hang halfway. My previous solution was to turn off ACPI in BIOS.
We tested every major release of Fedora from Fedora 10 “Cambridge” through the most recent Fedora 14 “Laughlin” Alpha build.
Up for testing was a Lenovo ThinkPad R52, Lenovo ThinkPad T60, and a Lenovo ThinkPad T61.

From these battery power consumption results from the past five Fedora releases using three different notebooks, it does not appear that the power performance is vastly improving — or at least just not in the past two years for the selection of hardware we used.
This is one problem that has affected me the most in my history of Linux usage, so far. Imagine, for two full years I just din’t know that the solution to this problem is so simple. Too late of me to find out. Anyway, better late than never.
So the problem is, with my graphics card GeForce FX 5200, Ubuntu liveCD/post-installation boot will hang mid-way, with the boot-screen freezing or a big set of hexadecimal codes getting emitted.
Anyone who’s worked on Linux must’ve come across a fair share of ACPI-related problems – lockups, standby problems etc. Some of the “solutions” is to disable ACPI support by passing the noacpi parameter during boot-up. So why is ACPI so problematic under Linux?
