--- Comment #3 from Eike Hein <h...@kde.org> --- It works fine for me, but note that you can't use xprop. xprop -s uses XChangeProperty, which can't set the WM_CLASS property because it doesn't support the stupid special format history cooked up for WM_CLASS (two consecutive null-terminated strings in a string prop for the two parts that make it up). I recommend using xdotool, which uses XClassHint and can set the required struct format. E.g. I turned my Firefox into Konversation with: xdotool set_window --class konversation 0x4e00010 xdotool set_window --classname konversation 0x4e00010 When you then use the context menu to add a launcher, and make sure Firefox is later using this WM_CLASS again, things fall into place. -- You are receiving this mail because: You are watching all bug changes.
