I have made some changes to xflock4 shell script. That is currently
only on my local git branch as a single commit. I guess you want that
the result is done in more than one commit, because there are a few
changes, though it is extra work.
I Cc:ed this to user mailing list, too, because I am interested in
Here are some related bug issues:
I tried to do the changes so that the modified xflock4 could be used
as such with older releases of Xfce4, too.
Below is the summary of the changes in git. Any comments?
Add known lockers and features in xflock4
Make xflock4 executable.
Unset IFS to get expected word splitting for sure. Use bash settings
to find errors more easily.
If the script is run in terminal, apply 1 second delay before launching
a screensaver to avoid unwanted effect when raising key up.
'gnome-screensaver-command --lock' returns always 0, so it has to be
handled specially. Tested on gnome-screensaver 3.6.1; the project
seems to be unmaintained.
Recognize new fallback screensavers:
light-locker (which also turns audio off while locking)
Recognize new fallback lockers:
/general/LockCommand is evaluated with care so that user does not
accidentally run e.g. a shell function, instead of a command, but user
has an option to run shell commands by starting the line by ';', '&&'
or '&' or by postfixing the initial command by '&'. User can pass
quoted arguments for the desired command.
Support new xfconf properties of xfce4-session channel:
/general/LockCommandForks (boolean; default false):
If the locker set in /general/LockCommand does not fork, this has to be
false so that xflock4 exits before unlocking; it will exit one second
after launching the command then.
/general/LockSetDPMS (boolean, default is false):
Whether to change DPMS setting for the locker. DPMS is never applied
for fallback screensavers and always applied for fallback lockers.
/general/LockInitialDelayDPMS (unsigned integer; default is 1):
Apply DPMS mode after this initial delay in seconds after the locker is
started. Actual delay is at least 1 second if /general/LockCommandForks
/general/LockDelayDPMS (unsigned integer; default is 15):
Apply DPMS mode after this amount of time of inactivity in seconds.
The old setting is restored after locker exits. This does not have an
effect if /general/LockCommandForks is true. This does not have an
effect either if the locker set in /general/LockCommand forks (because
it exits right off).
/general/LockModeDPMS (string with allowed values
standby, suspend and off; default is off):
Some DPMS mode might work better than other depending on system.
