It’s the moment I’ve been dreading all week, when I realize that I’ve hit a wall with Ubuntu and can go no further. Today, the wall in question is ACPI support, which in version 7.10 is simply broken.
Install “Gutsy” onto a notebook computer (take your pick of make/model – the problem seems to transcend the major brands), execute a suspend/resume cycle (for example, by closing and reopening the screen/lid), and wham! You’re in the Linux ACPI twilight zone.
In my case, the result is a kind of “black screen of death,” with no way to recover outside of a hard power-off/reboot.
