Hi, I've created a program called `xcursorclamp' which works around this issue by automatically calculating which regions of the virtual screen are invisible and creating undecorated windows that cover these regions. Whenever the mouse cursor hits such a window, the program will clamp the cursor to the nearest visible region. It will adjust automatically when the invisible regions change as a result of the user changing the X monitor configuration while the program was running.
Of course xcursorclamp is free software (GPLv3+), see http://sourceforge.net/projects/xcursorclamp/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/389519 Title: Cursor can move off-screen when dual-monitors do not form rectangular area -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
