The hang is caused by DISPLAY=:0 LANG=C xrandr | grep ' connected ' | cut -d ' ' -f1 which, when run manually from the command line, gives "xrandr: Failed to get size of gamma for output default default" [sic!] Disabling the entire routine with -foreach (`DISPLAY=:0 LANG=C xrandr | grep ' connected ' | cut -d ' ' -f1`) +foreach('') fixes the issue for singlehead mode, but breaks multihead mode. So, two suggestions: 1) STDERR from xrandr should go to /dev/null or to a log file/syslog, so -foreach (`DISPLAY=:0 LANG=C xrandr | grep ' connected ' | cut -d ' ' -f1`) +foreach (`DISPLAY=:0 LANG=C xrandr 2>/dev/null | grep ' connected ' | cut -d ' ' -f1`) 2) A simple fix could be if (1 < `DISPLAY=:0 LANG=C xrandr | grep ' connected ' | wc -l`) { foreach (`DISPLAY=:0 LANG=C xrandr | grep ' connected ' | cut -d ' ' -f1`) { ... } } I'm sure there might be a more elegant solution that works within the foreach loop, but "Hanc marginis exiguitas non caperet." -Stefan
