I had the same problem on my new laptop (Clevo P650RA), and adding 'i8042.reset' to GRUB_CMDLINE_LINUX_DEFAULT fixed it for me. Shouldn't this be enabled by default?
This is on "Ubuntu Xenial Xerus (development branch) - Release: 16.04" by the way. My exact kernel error was: i8042: failed to resume active multiplexor, mouse won't work In that case, the mouse indeed didn't work, but neither did the touchpad. Closing the laptop lid, waiting for a couple of seconds for it to suspend again and reopening the laptop lid was a workaround to resolve the situation, but the i8042.reset takes away the need to do so. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1014240 Title: [Asus eeepc 1225B] Keyboard and Touchpad randomly not working at startup Status in linux package in Ubuntu: Expired Bug description: Usually, once every 5-6 times when I reboot or awake form hibernate, the touchpad and keyboard do not work: no way to input text and login so I need to hard reset the laptop. I can ssh in (so the system is not frozen) and Fn+keys to change screen brightness etc always work. I collected X and kernel logs when it happens (by logging in remotely via SSH) but I'm not able to understand what is going on. This issue is reported in multiple forums, and affects Asus 252b as well (same laptop model for US market).
