Hi. I need help to modify my application to prevent computer entering
sleep state while the app is doing something....
On windows i achieve this like so:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i {$IFDEF
Windows}   SetThreadExecutionState(ES_CONTINUOUS OR ES_SYSTEM_REQUIRED
OR ES_AWAYMODE_REQUIRED);{$ENDIF}
Any ideea on how can i do this on Linux..manly Ubuntu 18.04 x64.
Thank you very much.

What I can find is this, where FPC should be capable of doing both,
however I prefer the dbus way as X may not be available in the future
when wayland finally takes over. See:
http://wiki.freepascal.org/FPC_and_DBus

Yes, I agree, but the wiki entry is not finished and a bit marginal.
There is far better code however:
If you are new to dbus programming maybe these articles by Michael can
Canneyt can help:

Thank you both! :-)
@Thaddy The sorces posted for dbus does not compile anymore so i will
try using dbus-sent in a Tprocess
Thank you again.

Yes i Saw that. A quick Fix is to make the property a VAR

@Thaddy Please, can you be more specific?
What did you changed in order to compile the 2 bundled examples? Thank
you.

Me again...i am unable to sort this out... :/ It is beyond my skills.
Could someone provide an quick example how to call a dbus method using
dbus unit from fpc? "dbuscomp" i am unable to make it to compile.
Thank you very much.

check if  the dbus shared libraries have the extension .so and not
so.1 or something. If so, create a symlink or copy.

This is not the problem.
I need an working examle using dbus unit as the wiki is incomplete or
an updated dbuscomp unit which i could compile. The posted one has
methods which are no longer available in dbus.
Thanks again.

OK I will come up with something new (but these calls are still
available afaik AND tested!) Not based on the wiki but based on the
article.

Thank you @Thaddy.   I am waiting eagerly for your example.
