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?
Reinstall or install input device drivers.
sudo apt-get install xserver-xorg-input-all
sudo apt-get install --reinstall xserver-xorg-input-all
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.
In my case it had something to do with the graphics card driver and this fixed me (if you use some latest nvidia graphics card then getting the updated driver may work) --
sudo apt-get install nvidia-current-updates
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
