Hello, I'm looking for what is proper method to inhibit screensaver(DPMS) without xscreensaver, KDE, GNOME ... . My video player 'bomi'(was cmplayer) try these, in order, ~~~ [App] Initialize screensaver functions. [App] Try to connect 'org.gnome.SessionManager'. [App] Failed to connect 'org.gnome.SessionManager'. Fallback to 'org.freedesktop.ScreenSaver'. [App] Failed to connect 'org.freedesktop.ScreenSaver'. Fallback to XResetScreenSaver(). [App] Disable screensaver with XResetScreenSaver(). ~~~ But it does not working. I didn't know how I directly deal with X11 lib. Fortunately, I found 'resetScreenSaver' from 'Graphics.X11.Xlib.Misc' that say interface to XResetScreenSaver(). resetScreenSaver.hs : ~~~ import Graphics.X11.Xlib import Graphics.X11.Xlib.Misc import Control.Concurrent import Control.Monad main = do dpy <- openDisplay "" forever $ do putStrLn "reset" resetScreenSaver dpy threadDelay (5*1000000) ~~~ ~~~ $ xset s 10 $ runhaskell resetScreenSaver.hs ~~~ Unfortunately, It does not working. `activateScreenSaver` and `forceScreenSaver` also does not working. But `xset s reset` is working as intended and also there is `xdg-screensaver [ suspend | resume | reset ]` command from 'xdg-utils' package (Arch). It looks like abstraction layer for xset, xscreensaver, KDE, GNOME ... . So I'm curious about whether this is bug of xorg or I misunderstand something. And what is right way to do this if I don't want any screensaver daemon? `xset s` or `xdg-screensaver`? Thanks.
