I will try nemo anyway, if I find some time, so this is a good idea.

The libX11.so with xcb causes problems (keyboard does not work for non-Qt programs including hildon*), so we need an independent copy for Qt5. I named it libXc11.so and Qt5 will be linked against it from now on. I've updated the instructions in the wiki (wiki.maemo.org/Qt5-Maemo5-Development). Please update your checked out copy (if you have one), remove libQt5Widgets.so.* and plugins/platforms/libqxcb.so (those are the only libraries directly linked against X11 - a nice effect of the platform abstraction Qt5) and remake.


I accidentally also uploaded "libx11-data" with the former series of packages (libx11* +withxcb) which causes some problems now (should be identical to the standard one, but the repo produces some size mismatch), see http://talk.maemo.org/showthread.php?p=1360937.
