Keyboard and mouse not working after update to 15.04

[Grzegorz Galezowski]

After turning on the system, mouse pointer is not visible and first key press on keyboard is ignored.

When I press mouse button (left or right), mouse pointer appears and I can control it, but when I leave it for few seconds, it disappears again.

As for the keyboard, the first key press is ignored (e.g. when I try to type "zone", only "one" is visible on the screen because the first key is ignored) - this behavior repeats itself after few seconds of not pressing any keys.

My keyboard has backlight option and when I turn it on, the light flickers and disappears when the keyboard gets "disconnected".

Disconnecting and connecting again mouse and keyboard makes the issue disappear - from that moment on, both mouse and keyboard work like a charm (until reboot).

One more comment - I tried using newer kernel from the ubuntu mainline (version 4.0) and the behavior persists.

This bug was fixed by some of the recent updates. Now my mouse and keyboard both work fine. I saw linux firmware package being updated - maybe this is what fixed it?

Anyway, I am fine now, thank you for your hard work!

Hi, I haven't used Ubu for some time and now I am back and it seems I was wrong in that the bug was fixed. It just started showing up less for some time.

I dug into the problem and it seems that USB ports are being suspended. I found that laptop-mode tools do this when one is on battery, but it happened to me when I has AC connected (sometimes, and sometimes not). Uninstalling laptop-mode tools seems to have fixed the problem.

Uninstalling laptop-mode tools seems to have fixed the problem, so I am changing the package affected

Seems to have the same issue (Kubuntu 15.10) was introduced a few weeks ago. As I am weekly updating the system.
