This bug is because of kernel upstream bug https://bugzilla.kernel.org/show_bug.cgi?id=52471
All the info is in that bug report, including 2 patches to fix it. In short form, the (doomed to fail by timeout) battery status reporting injects a 5 second delay in keyboard device removal. Due to races in the kernel bluetooth code, this leads the code to remove devices from sysfs in the wrong order. This in turn leads to udev events being sent out with truncated device paths. This in turn causes Xorg evdev to receive the 'remove' events, but ignore them because they cannot match them up. When the keyboard re-connects, Xorg then sees the 'add' events matching a keyboard it thinks it already has, so ignores them ... so your keyboard doesn't work (or mouse too, if bluetooth as well!). IMHO This is NOT a problem in Xorg - it is a kernel issue leading to faulty udev events. Note the Google Chrome people patched their Xorg to work around the issue ... but the real fix should be in the kernel. ** Bug watch added: Linux Kernel Bug Tracker #52471 http://bugzilla.kernel.org/show_bug.cgi?id=52471 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-evdev in Ubuntu. https://bugs.launchpad.net/bugs/1075478 Title: bluetooth keyboards and mice not working after suspend/resume Status in xserver-xorg-input-evdev: Unknown Status in “xserver-xorg-input-evdev” package in Ubuntu: Confirmed Bug description: After upgrading to Ubuntu 12.10 I encountered the following problem: I have my apple wireless bluetooth keyboard paired up to Ubuntu, and it works fine when I boot up my laptop (HP EliteBook 8530w) as soon as I hit the login screen. However, if I then suspend and resume my laptop again, the bluetooth keyboard does not respond anymore. According to the bluetooth GUI applet it is still succesfully paired up and connected, and I see the green light on my keyboard blinking a few times when I hit a key for the first time after resume which is also the case when it _does_ work, but I get no response whatsoever from Ubuntu when typing on my keyboard. "sudo service bluetooth restart" does not work. Please let me know what additional information to provide.
