My graphic card seems incompatible with Kubuntu 13.10

[genetin]

First, do not consider extra debug information attached to this bug report : as the bug makes my PC unusable, I report the bug from a second PC.

I cannot install Kubuntu 13.10 on my PC, because of lots of display problems : see attached file as an example.
I have a "SyncMaster 203B" screen and a "Nvidia GeForce 7300 GT" graphic card.

I have successfully installed Kubuntu 12.04 LTS, then I have upgraded to 12.10 without problem.
When I try to upgrade to 13.10 I have again the same problem.

Additional info : I have launched Ubuntu 13.10 (=> with Unity), and it worked correctly.

The bug has been analyzed by a KDE contributor. It seems to be a Kubuntu bug.
See https://bugs.kde.org/show_bug.cgi?id=331433 for details.

Actually he said that qdbus not working is an issue, alas, it is a configuration/setup issue. Whenever both qt4 and qt5 are installed the straight forward call to qdbus in fact is piped through qtchooser which in turn will try to use the qt5 binary.

Since this is still a KWin issue, marking it as invalid.
