Comment 51 for bug 973778

System detail: Dell Vostro 1500, Ubuntu 12.04 LTS, dm Xubuntu-Desktop.

Summary: very chaotic unstable behavior...unusable almost.

- There is a major issue with the stability and performance of the Power Manager where the power manager plugin panel is very slow to load, it loads about 20 seconds after the Wifi network manager launches and connects, it takes forever when it should load instantly before all the other indicator plugins.

- When I go into XFCE control panel settings and click Power Settings, I get a blank screen and this is on a fresh install of 12.04 LTS with XFCE downloaded from the Software Centre.

- When I attempt to click on the preferences icon in the panel plugin, nothing happens and then a pop up emerges with a smiley screen repeating the Power Manager version information. Clicking on the button OK keeps me in a perpetual loop where the dialog box never closes. I have to close it with the X window closer button. When I attempt to reopen the dialog box again from the indicator plugin panel, it is totally blank.

System detail: Dell Inspiron 1000, Lubuntu 12.04 LTS, dm LXDE.

I also have an install of Lubuntu 12.04 on another machine and for some reason it works perfectly every single time. Oddly the above error is only found on XFCE based desktops and does not affect the other DM's.
