--- Comment #13 from Ivo Šmerek <iv...@centrum.cz> --- Alright, I managed to get this working. It is related to the fact, that WM_CLASS property has two variables. Look at these two following commands. Command 1: > xprop -name "Talos - Linux - 64bit" -f WM_CLASS 8s -set WM_CLASS "Talos - > Linux - 64bit" Leads to: > $ xprop WM_CLASS > > WM_CLASS(STRING) = "Talos - Linux - 64bit" Command 2: > xdotool search --onlyvisible --name "Talos - Linux - 64bit" set_window > --class "Talos - Linux - 64bit" Leads to: > $ xprop WM_CLASS > WM_CLASS(STRING) = "", "Talos - Linux - 64bit" In xdotool they distinguish these variables as --classname and --class. When I change --class, KDE Task Manager react properly and remap particular .desktop file. But when I change only --classname, nothing happens. So if you think Task Manager works correctly, feel free to close this issue. -- You are receiving this mail because: You are watching all bug changes.
