Hi, I use a Kinesis Advantage USB keyboard with my Lenovo X230 laptop. It worked fine until yesterday when I updated my system. I have tested the keyboard with another laptop -- it works fine. I also tested another regular USB keyboard with this laptop -- and that works fine as well. It seems that the keyboard works immediately after I plug it in and continues to work as long as I continue to hit keys. However, if I stop clicking for more then 5 secs, it stops working permanently. I don't think that this is necessarily an xmonad issue since it happens in the login screen as well (I use Slim). However, when I log in with xfce, it does not happen for some reason. I'm at my wits end and I'm not sure what to do. When I plug the keyboard in, I see the following in the logs: ==> kern.log <== Jun 11 11:48:56 localhost vmunix: [ 1172.012627] usb 3-1.2: new full-speed USB device number 23 using ehci-pci Jun 11
