I have a Toshiba Satellite S55-A5154 with 14.04 installed. Every time it resumes from being suspended, neither the keyboard nor mouse work. What can I do to fix this or provide you with more info?
I've tried all the answers on this page, but they didn't really work. I thought reinstalling xserver-xorg-input-all worked, but it didn't. I recently found this page and the freezing hasn't happened since. What you do is edit
/etc/default/grub and change
GRUB_CMDLINE_LINUX_DEFAULT to have the value
"atkdb.reset i8042.nomux quiet splash" and then run
sudo update-grub and reboot. This also works on 16.04.
I've tried pretty much all fixes I could google (including the other answers to this question), but the only thing that helped was to install the hardware enablement stack:
sudo apt-get install linux-generic-lts-utopic xserver-xorg-lts-utopic \ libegl1-mesa-drivers-lts-utopic xserver-xorg-video-all-lts-utopic \ xserver-xorg-input-all-lts-utopic
