This problem still exists in Karmic Kubuntu, even though gtk-qt-engine is now replaced by kcm-gtk. The workaround is still the same. First you need to configure theme separately for root/sudo by starting system settings with command:
kdesudo systemsettings The file .gtkrc-2.0-kde4 will be created in the root directory after you choose theme for GTK apps under the GTK Appearance. This file is worthless until you create .gthrc-2.0 symbolic link that points to it. For the security-conscious users out there, use the following command: sudo ln -s /root/.gtkrc-2.0-kde4 /root/.gtkrc-2.0 This avoids linking user's file to root's file. I just hope that Kubuntu developers will some way, some how, make this work out of the box, so new users won't have to go through this. I've filed a bug report on this, but it is being mark as a duplicate of gtk-qt-engine bug. https://bugs.launchpad.net/ubuntu/+source/kcm-gtk/+bug/406747 -- [Hardy] The gtk-qt-engine doesn't work while staring applications as another user https://bugs.launchpad.net/bugs/205201 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
