Hey Photon if you are right, starting the system without X will solve this problem. Looks like an interesting ideal! I'll try this tomorrow. We discussing probably several issues with similar behaviour. Is it one bug or several is only a question of definition. One thing is definitely known, after the update from10.04 to 12.04 several systems don't power off any more. It's not known which kind of systems is affected. From 5 PCs with 12.04 near me only one system is affect, one of these PCs uses nvidia proprietary graphics driver and it is *NOT* affected. Another one has a nvidia graphics with nouveau driver. I tested this by install and uninstall of proprietary graphics driver and can't reproduce this issue. Two Lenovo laptops are not affected, no nvidia graphics. One of this laptops has similar graphics as the affected PC. But why this PC can't shutdown? Probably damages nvidia driver something in ACPI or making something else what can cause this issue, but it can't be a root cause. We probably need to collect more information about affected systems. Then we hopefully know how to reproduce this issue.
