I've once again switched my window manager. I dropped Xfce in favour of Fvwm (actually Fvwm Crystal since I dont want to mess too much with configuration files). Besides I also use Kazehakase instead of Firefox as my main browser now. It's all a little less convenient but the performance gain on my old laptop is great. Furthermore I compiled myself a new kernel and now got full working powermanagement features (I had experienced overheating during emerge -unD world ).
Other than that I visited Braunschweig today, where Daniel Willmann from the FSO-Team organised a buzz-fix party for neo freerunners. Now can enjoy buzz-free phone calls
