I suggest adding a small script

Hello everybody!
I suggest that you automatically add a small script to the startup when installing.

#!/bin/sh

trap "(xscreensaver -no-splash &); xset +dpms; exit;" 1 2 3 8 9 14 15;

function FULLSCREEN(){
    SCRN_SVR_PID="$(ps aux | grep -P 'xscreensaver\ -no-splash' | awk '{print $2}')";
    if xset -q | grep -Pq 'DPMS is Enabled'; then
        if [[ "a$SCRN_SVR_PID" != "a" ]]; then kill -9 $SCRN_SVR_PID; fi
        xset -dpms;
    fi
}

function NOT_FULLSCREEN(){
    if xset -q | grep -Pq 'DPMS is Disabled'; then
        (xscreensaver -no-splash &);
        xset +dpms;
    fi
}

while true; do
    FS_STATUS="false";
    win_id_list=`xprop -root _NET_CLIENT_LIST | sed -e 's/.*\#//g' | sed 's/\,/ /g'`;
    for win_id in $win_id_list; do
        WinFullScreen=`DISPLAY=:0 xprop -id $win_id | grep _NET_WM_STATE_FULLSCREEN`;
        if [[ "$WinFullScreen" = *NET_WM_STATE_FULLSCREEN* ]]; then FS_STATUS="true"; fi
    done
    if [[ "a$FS_STATUS" == "atrue" ]]; then
        FULLSCREEN;
    else
        NOT_FULLSCREEN;
    fi
    sleep 5;
done

Please forgive for my bad English =)

Thank you for your comment. This script disable screensaver (i use xscreensaver) when application opened in fullscreen mode and running screensaver when application opened in window mode.

Re: I suggest adding a small script

You should not kill xscreensaver by `kill -9`. Manual page of `xscreensaver-command` tells so: "Warning: never use kill -9 with xscreensaver while the screensaver is active.  If you are using  a  virtual root  window manager, that can leave things in an inconsistent state, and you may need to restart your window manager to repair the damage." Use `xscreensaver-command -exit`, instead. And you can test, if the daemon is running by `xscreensaver-command -version`.

Not everybody is using xscreensaver. I think it is better to use `xdg-screensaver suspend` and `xdg-screensaver resume` to control running screensaver.
Note also that latest versions of xscreensaver have `xscreensaver-systemd` that is able to inhibit screensaver in some cases:

Re: I suggest adding a small script

The topic is outdated, perhaps no longer relevant.

I have an offer to add this to the distribution. I own English badly, but I hope I managed to convey my idea with the code.

I hope you understand me =).
