Comment 7 for bug 105259

Yep, crash with unsupported policy is also reported by other users. See bug 112120.
There you can also find a quick fix for this crash. The rest of this report is enhancement and therefore I will mark this as Wishlist.

I will improve this further for next version of kde-guidance (should be released in Gutsy release). We want to keep guidance power-manager simple, this is why we do not want to expose all governors supported in HW, but rather make better defaults based on what HW supports. We already have "Dynamic" policy, which first tries "ondemand" governor and if that one does not work, switches to "userspace". I will change Dynamic behavior for AC and battery mode, so that the following governors will be used in different policy modes:

Dynamic/AC: ondemand, conservative, userspace
Dynamic/Battery: conservative, ondemand, userspace
Powersave: powersave
Performance: performance
