Mouse and Keyboard Failure on ThinkPad 520 laptop
I have severally had my ThinkPad 520 laptop, which has a 64-bit system, freeze. During the occurrences, the mouse and the keyboard could not work. This problem with my ThinkPad 520 laptop began at a time when I was viewing a movie using Mozilla which required me to install Adobe Flash. The next time the mouse and keyboard problem with ThinkPad 520 laptop occurred I was preparing a presentation using Libre Office. The message on the syslog was “I cannot attach the whole file”. It seems that there is conflict with Alsa player. I think the issue is a problem of Ubuntu installation though I can’t tell what it really is. Please advise me.
