Since this bug (!) is set to whichlist priority, I decided to write my own code. I wasn't able to find the source of the problem, so I spent one weekend to learn C++ with Xlib and wrote a little app that creates a undecorated black window that prevents the mouse from entering it. If initialized such that the window covers the void, the mouse effectively cannot go there.
Take a look at the readme.txt for a detailed description + example or read the source code directly. ** Attachment added: "tiny program to prevent the mouse from entering the void." http://launchpadlibrarian.net/36255064/XCreateMouseVoid.tar.gz -- Pointer goes offscreen on non-rectangular dual-head https://bugs.launchpad.net/bugs/373367 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
