This appears to be a two part problem: 1. HAL doesn't let guidance-powermanager have access to the required device:
Warning: in getBrightness(): org.freedesktop.Hal.Device.PermissionDeniedByPolicy: org.freedesktop.hal .power-management.lcd-panel no <-- (action, result) 2. guidance-powermanager then crashes because it doesn't have an old brightness value: File "/usr/share/python-support/kde-guidance-powermanager/powermanage.py", line 287, in getBrightness return self.old_b AttributeError: PowerManage instance has no attribute 'old_b' ** Changed in: hal (Ubuntu) Importance: Undecided => Medium ** Changed in: hal (Ubuntu) Status: New => Confirmed -- Cancel button in kde-guidance-powermanager doesn't do anything https://bugs.launchpad.net/bugs/183656 You received this bug notification because you are a member of Kubuntu Team, which is subscribed to kde-guidance in ubuntu. -- kubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
