Basically, I have a change to be done in
/usr/src/qt/src/src/gui/kernel/qclipboard_x11.cpp
There is a 10s timeout that causes apps to hang on shutdown (search the file for the word "reasonable"). Not very reasonable, in fact.
For illustration, this is what I want to mitigate - I can't open another instance of Okular until the 10 seconds timeout ends.
<terminal>
okular(9173) Okular::Utils::realDpiY: Pix: 1080 MM: 285
okular(9173) Okular::Utils::realDpiX: Pix: 1920 MM: 508
okular(9173) Okular::DocumentPrivate::openDocumentInternal: Output DPI: QSizeF(96, 96.2526)
...
(window is closed)
...
(10 seconds later)

QClipboard: Unable to receive an event from the clipboard manager in a reasonable time
Here I should be able to fix it:
<file qtclipboard_x11.cpp>
XEvent event;
// waiting until the clipboard manager fetches the content.
if (!X11->clipboardWaitForEvent(ownerId, SelectionNotify, &event, /*HERE->*/ 10000, true)) {
qWarning("QClipboard: Unable to receive an event from the "
"clipboard manager in a reasonable time");
}
I've changed this to 3 seconds, which should be much better.
How to make the changes apply?
Is there some makefile to run to rebuild Qt from these sources, or am I doing it completely wrong? I assume there's some qt library object file that needs to be rebuilt, but I can't find a way to do it.
Thanks.
btw. it's Arch install with Xfce, if it's relevant in any way
