I have written a qt tray-icon based background app that basically keeps the mouse in the screen by polling for when its gone out of the screen, but this is a very suboptimal solution since it has to poll many times a second and eat cpu. It sometimes reaches 1% cpu even! And X is still getting the events, so it kind of bounces at the edges, not a great solution (but better than nothing).
A proper solution would be to somehow get the driver or the X system involved, because we'd want to intercept these pointer events before they reach X or at least before it sends them on to client applications. If someone has information on where to start looking if I wanted to mess around with this at a higher level (X or driver or something) please let me know - I have the means, but I'm kind of lost in the architecture here. There are so many interacting subsystems... -- 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
