>Description:
When using a USB KVM switch, after switching back and forth from another machine a few times, mouse behaviour functions erroneously in Xorg (tested with both fluxbox and gnome 2.8). The mouse seems to focus on the previous location instead of the current position. For example, if having last used the mouse in a window, even if you switch to another window, the mouse will behave as if it was still positioned over the previous window (right click results in menu for previous window, etc.).
>How-To-Repeat:
As above
>Fix:
By unplugging the USB mouse and plugging it into the PS/2 port through an adapter and running moused, then plugging it back into the USB port, correct behaviour resumes. Could the problem be with some kind of loop or leftover queues when the USB mouse is detached?
