So far I can not install any BSDs on it (Freebsd, NetBSD and OpenBSD). I need to add "acpi=off pnpbios=off" for Ubuntu 8.04 to boot. But many people have the same problem with Ubuntu so I am not 100% sure if it is 100% Acer's problem. Ubunut 8.10 is ok. All the year 2006/2007 Linux do not work at all with this desktop.
