I have the following Problem with MATE: The hp-systray (hplip) is not showing up in the Panel as it should, although it is in the MATE autostart programs. It does show up in KDE4 and in XFCE4, but not in MATE. The process "hp-systry -x" is listed when doing a
ps -x
and when killing it and reloading it by command line, then the blue icon does show, but it is useless, because when right-clicking on it, only a grey bar shows instead of the hplip-menu as it should. Any idea what is wrong with MATE here? I installed it from packages, maybe one of it is wrong and should be recompiled from ports?
