Running a Xubuntu 16.04 on my laptop works fine as long as I start a session via XDMCP from a Windows computer (using VcXsrv). Then I don't see any xfce power applet with the current battery status. Reason: no xfce4-power-manager running If I try to start it manually with "xfce4-power-manager --debug" I get... $ xfce4-power-manager --debug TRACE[xfpm-main.c:192] xfpm_start(): Starting the power manager Xlib: extension "DPMS" missing on display "192.168.23.177:42.0". ...

self reply: I'm currently running an XDMCP session and I see the power applet, xfce4-power-manager is up and running, confuses me.
I still have the problem of a vanishing power applet in XDMCP sessions. Just restarted it from a terminal and saw these lines when it vanished again: TRACE[xfpm-manager.c:490] xfpm_manager_alarm_timeout_cb(): Alarm inactivity timeout id 2 TRACE[xfpm-manager.c:490] xfpm_manager_alarm_timeout_cb(): Alarm inactivity timeout id 1 The program 'xfce4-power-manager' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch (invalid parameter attributes)'. (Details: serial 1029 error_code 8 request_code 133 minor_code 8) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) May be these lines are helpful for anybody?
