Comment 26 for bug 469365

Good news, everyone: I finally managed to get this fixed upstream. The complete mouse grabbing code had to be moved from on thread to the other, either gtk+ or x.org broke multiple XDisplay connections from multiple threads. Hopefully the maintainers can update the terminatorx package to the new version soon. If you do not want to wait for the Ubuntu package to upgrade and know how to install software manually, please give the new version a try: Get your system ready to build terminatorX by running:

sudo apt-get build-dep terminatorx

Grab the tarball (http://terminatorx.org/dist/terminatorX-3.83.tar.bz2), extract and build with the standard ./configure; make install routine.

Works flawlessly on Maverick/x86_64, test-compiled for x86 as well. Good luck.
