Review request for kde-workspace, Martin Gräßlin and Thomas Lübking.


added xcb_connection_has_error() check

Repository: plasma-workspace


this patch makes kcminit behave like in kde4: it uses proper xcb screen count which may be different from QGuiApplication::screens().count().

for example when i connext external monitor via vga to my laptop, xcb screen count is still '1', while QGuiApplication::screens().count() returns '2'.

switching from QGuiApplication to QCoreApplication still wasn't possible because modules like 'mouse' need gui initialized and would crash if kcminit uses QCoreApplication.

Diffs (updated)

  startkde/kcminit/CMakeLists.txt b17951f 
  startkde/kcminit/main.cpp 1008966 



i have built kcminit on ubuntu vivid alpha 32-bit, replaced binaries and libraries in the system and successfuly could run kcminit_startup and reboot also went fine.
