Hello:
I am trying to port two of my apps from Qt 4.8.6 to Qt 5.7.0
(I am also moving from RHEL5 to RHEL6 at the same time.)
I can build them and one appears to run properly, I just get a
little noise on start-up...
App #1:
XXX-lx01:app: App: *W*, failed to get the current screen resources
(/nobackup/XXX/qt/qt-everywhere-enterprise-src-5.7.0/qtbase/src/plugins/platforms/xcb/qxcbconnection.cpp:412,
void QXcbConnection::initializeScreens())
App: *W*, QXcbConnection: XCB error: 173 (Unknown), sequence: 170, resource id:
91, major code: 150 (Unknown), minor code: 20
(/nobackup/XXX/qt/qt-everywhere-enterprise-src-5.7.0/qtbase/src/plugins/platforms/xcb/qxcbconnection.cpp:996,
void QXcbConnection::handleXcbError(xcb_generic_error_t*))
App #2:
The other one produces quite a bit more noise and never appears on the screen,
even though the debugger shows it in the main event loop...
App: *W*, failed to get the current screen resources ((null):0, (null))

I see items in this area as a result of a web search,
but no recommendations as to the solution.
Does anyone have any experience in this area.
Thanks.
Bill
