This bug was originally reported on Launchpad at https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/447728 "I'm using fully updated karmic beta amd64 on a Dell Inspiron 1520 with gnome-power-manager 2.28.0 on linux kernel 2.6.31-13-generic. I have it set in System> I have observed that if I suspend or hibernate, after waking the display behaves normally. If I kill gnome-power-manager, the display behaves normally. [xset force dpms off] blanks the display normally. The display behaved normally under Ubuntu 9.04. Here is lshal -m although, I am not sure this is still relevant due to devicekit. . . This is the lid being closed, waiting for the display to incorrectly come back on, then opening the display: Start monitoring devicelist: ------------------------------------------------- 22:12:20.666: computer_logicaldev_input condition ButtonPressed = switch-videomode 22:12:20.668: computer_logicaldev_input_5 property button.state.value = true 22:12:20.669: computer_logicaldev_input_5 condition ButtonPressed = lid 22:12:21.551: platform_i8042_i8042_KBD_port_logicaldev_input condition ButtonPressed = switch-videomode 22:12:24.015: computer_power_supply_battery_BAT0 property battery.voltage.current = 12606 (0x313e) 22:12:24.280: computer_logicaldev_input condition ButtonPressed = switch-videomode 22:12:24.283: computer_logicaldev_input_5 property button.state.value = false 22:12:24.289: computer_logicaldev_input_5 condition ButtonPressed = lid 22:12:24.945: platform_i8042_i8042_KBD_port_logicaldev_input condition ButtonPressed = switch-videomode Here is lshal -m with gnome-power-manager killed and X correctly handling the blanking: Start monitoring devicelist: ------------------------------------------------- 22:13:27.328: computer_logicaldev_input condition ButtonPressed = switch-videomode 22:13:27.335: computer_logicaldev_input_5 property button.state.value = true 22:13:27.337: computer_logicaldev_input_5 condition ButtonPressed = lid 22:13:27.965: platform_i8042_i8042_KBD_port_logicaldev_input condition ButtonPressed = switch-videomode 22:13:31.132: computer_logicaldev_input condition ButtonPressed = switch-videomode 22:13:31.144: computer_logicaldev_input_5 property button.state.value = false 22:13:31.145: computer_logicaldev_input_5 condition ButtonPressed = lid 22:13:31.791: platform_i8042_i8042_KBD_port_logicaldev_input condition ButtonPressed = switch-videomode There is no difference I can see, so I would think that this further proves that the problem is with gnome-power-manager."
What does "devkit-power --dump" say? What version of DeviceKit-power are you using?
devkit-power --dump Device: /org/freedesktop/DeviceKit/Power/devices/line_power_AC native-path: /sys/devices/LNXSYSTM:00/device:00/ACPI0003:00/power_supply/AC power supply: yes updated: Wed Jan 20 15:16:02 2010 (1505 seconds ago) has history: no has statistics: no line-power online: yes Device: /org/freedesktop/DeviceKit/Power/devices/battery_BAT0 native-path: /sys/devices/LNXSYSTM:00/device:00/PNP0C0A:00/power_supply/BAT0 vendor: Panasonic model: DELL MN1278 serial: 1286 power supply: yes updated: Wed Jan 20 15:16:06 2010 (1501 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: fully-charged energy: 56.61 Wh energy-empty: 0 Wh energy-full: 56.61 Wh energy-full-design: 56.61 Wh energy-rate: 0.0111 W voltage: 12.612 V percentage: 100% capacity: 79.451% technology: lithium-ion Daemon: daemon-version: 011 can-suspend: yes can-hibernate yes on-battery: no on-low-battery: no lid-is-closed: no lid-is-present: yes I don't know how to find the version of devicekit-power
