Thank you very much for your afford!! I compiled LyX 1.6.3 as described, worked well. But the error was still there, didn't change anything. Then I upgraded to QT 4.5.1 --> this was the solution! I upgraded QT4 in an other way. In Ubuntu I added deb http://ftp.iinet.net.au/pub/ubuntu/ karmic main restricted universe To synaptic / package sources Then I created the file (sudo nautilus) /etc/apt/preferences and added the from John C. McCabe-Dansted described lines: Package: * Pin: release a=jaunty in-Priority: 700 Package: * Pin: release a=karmic Pin-Priority: 600 Package: libqt4* Pin: release a=karmic Pin-Priority: 800 Package: qt4* Pin: release a=karmic Pin-Priority: 800 [perhaps it would work without preferences?] Then went to synaptic and selected libqt4-core for updating, synaptic automatically selected the rest and made an update Finally i deactivated the deb http://ftp.iinet.net.au/pub/ubuntu/ karmic main restricted universe from sources. I chose this way, because the first described way with update/upgrade didn't work on my pc. Thank you all for solving the problem! Michael
