Hello all, I bought a new second monitor and got an issue with my dynamic xmobar setup. I use a laptop which is connected to both monitors via a docking station. This is the configuration I want to achieve with independent bars on monitor one and two. Note: when docked I do not want to turn the internal display off, this has to be done in order to save a configuration in autorandr. If anyone has a suggestion to avoid this problem, feel free to share. Configuration of xrandr(autorandr): 1. Undocked Internal display primary output 1. Docked Internal display off First monitor set as primary Second monitor right of first monitor Xmonad Configuration: main :: IO () main = xmonad . ewmh . withUrgencyHook NoUrgencyHook . dynamicEasySBs (pure . barSpawner) . usePrefixArgument "M-u" . rescreenHook def{ afterRescreenHook = onMonitorChange } . spawnExternalProcess def $ myConfig `additionalKeysP` myKeys where barSpawner :: ScreenId -> StatusBarConfig barSpawner = \case 0 -> statusBarPropTo "_XMONAD_LOG_0" "~/.local/bin/xmobar ~/.config/xmobar/xmobar-old/xmobarrc -x 0" (xmobarPP 0) 1 -> statusBarPropTo "_XMONAD_LOG_1" "~/.local/bin/xmobar ~/.config/xmobar/xmobar-old/xmobarrc1 -x 1" (xmobarPP 1) _ -> mempty onMonitorChange :: X () onMonitorChange = do spawn "autorandr --change" Issue: When I plug my laptop into the docking station my rescreenHook gets executed which invokes autorandr to load my specified profiles, which - when docked - applies the rules for my docked configuration shown above. Xmobar spawns on monitor with ID 1 and indicates, that there is also a second monitor displaying a different workspace but somehow there is no xmobar present on the other monitor (ID 0). When I run the command defined in my barSpawner for monitor ID 0, the xmobar is spawned and works perfectly fine. Thanks for your help Jan
