Windows has the SetThreadExecutionState method that enables you to prevent monitor standby during program execution.
I’m searching for a Linux equivalent, but I can’t find anything useful.
I don’t want to disable the screensaver by calling a command, because if the program crashes after that, the screensaver will stay disabled until the user re-enables it.
The program is written in Qt, so a Qt friendly solution would be great.
Ideas anyone?
I was looking for this and couldn’t find a solution, but instead a workaround. Launching at the same time as the application (a video player) a little script to periodically check if the application process is alive, and if it isn’t, re-enable the screensaver. In my case using
xset s onandxset s off, then end the checker process itself. You can probably fork a process to the background so it stays alive and does its re-enable job reliably.
