I've set an old pc - 7 years , with AMD XP, KT400 and Radeon 9250SE - for one of my neighbours. Because of the age and lack of power i decided to install the LXDE version, a first for me. Unfortunately he has managed to mess it up already: he has deleted the "Quick Launch" applet and i don't know how to bring it back - or to reset the toolbar to its default. To be more exact i restored the App Launch Bar but i have no idea how you can add icons in it - by dragging doesn't work.
One more thing - which driver should i use for the video? Now i'm using the default one (the fglrx) and i experience problems in MPlayer and the X server crashes when i change the resolution.
