Sorry for the delay, I tested with 3.6.1 kernel release in: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6.1-quantal/
I got the same result, with a segfault occuring here: [ 288.950759] compiz[3498]: segfault at 60 ip 00007fb498d6eb60 sp 00007fffdbd32278 error 4 in libcomposite.so[7fb498d60000+23000] [ 289.307727] compiz[3540]: segfault at 60 ip 00007f53a2b11b60 sp 00007fff22c555a8 error 4 in libcomposite.so[7f53a2b03000+23000] ** Tags added: kernel-bug-exists-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Tags removed: needs-upstream-testing -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1060572 Title: XDMCP Failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1060572/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
