When I am dealing with resource intensive applications, like a game or blender or gimp, my mouse will become totally unresponsive until I restart my computer. I have a wireless keyboard and mouse combo from Logitech. When it happens my keyboard will always continue to work unless I unplug the receiver and plug it back into the same, or another usb port, in which case it too becomes completely unresponsive. However, during any stage of this problem I can plug in a usb corded keyboard and mouse and they will function just fine, as will all of the other usb ports and any devices plugged into them. The Logitech combo doesn't behave this way on any other combination of computer and operating system. I have no idea how to even go about fixing this, and I can't find a single useful article on the internet as they are all of the caliber you would expect to see from a user manual that came in a wireless combo box.
I can not replicate the problem, only encourage it.
It occurs most when using a resources intensive application, as described above.
It occurs less frequently when using a keyboard shortcut and moving the mouse simultaneously.
Least frequently of all it will simply stop moving of it's own volition almost immediately after having been nudged in any direction.
I have an amd phenom quadcore processor.
I am using Ubuntu 12.10.
Hmm... I can't think of anything else that would be relevant so just ask if you need more information.
Since posting this question I have discovered that corded mice will also become unresponsive, it just takes longer.
As well, after the problem occurs I can't hit Ctrl + Alt + F4 to load the console interface (which I am not sure how to use exactly or if it's anything like the terminal), and sometimes I will be presented with an I/O error which I haven't written down yet as i'm not convinced of it's relevance.
I know this probably isn't really a ubuntu problem as it functions fine with ubuntu on any other computer, but I don't know where else to turn, and to be fair it is only on ubuntu that this problem occurs in my current system.
