I don't know for the touchpad, but it is simple to reproduce the problem for a normal mouse on the current karmic:
Simply open the configuration editor and activate the left_handed gconf key and click with the left mouse button some item: the contextual menu does not appear, but the item gets selected as if a primary click occurred instead of a secondary click. However, if I used the Mouse control panel instead of the configuration editor to activate the left handedness of the mouse, the problem does not occur. Finally, I have been told that the problem is fixed in some 2.29.x version in GNOME, but for the moment I have not been able to verify it with Ubuntu lucid, as lucid does not start up properly here. -- Left handed mouse settings no longer working after system update https://bugs.launchpad.net/bugs/426675 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-settings-daemon in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
