Some additional info: I found the following package: "kde-config-qt-graphicssystem" and tried to configure the setting using it by running "kcmshell4 qt-graphicssystem"
It only provides three options. None of which are "native". It did *not* work! On the other hand, setting the env. variable as suggested by Frank did the job. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1077965 Title: qt4 applications over X forward run slower than with Ubuntu 10.04 LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qt4-x11/+bug/1077965/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
