$ sudo sed -i 's/XINERAMA/FAKEEXTN/g' /usr/lib/jvm/java-6-sun-1.6.0.04/jre/lib/i386/xawt/libmawt.so (I changed 1.6.0.03 to 1.6.0.04 because that is the version I am using) ** Changed in: sun-java6 (Ubuntu) Status: New => Confirmed -- Java 6 doesn't work in Kubuntu 8.04 https://bugs.launchpad.net/bugs/188961 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
