Ubuntu – Keyboard and mouse unresponsive after suspend

14.04keyboardmousesuspendtoshiba-satellite

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

Or:

sudo apt-get install --reinstall xserver-xorg-input-all

Basically, run this in a shell to confirm you are applicable to this solution:

dmesg | grep i8042

and confirm you get this output

[ 1.514469] i8042: PNP: PS/2 Controller [PNP0303:KBC,PNP0f13:MOUE] at 0x60,0x64 irq 1,12
[ 1.525273] serio: i8042 KBD port at 0x60,0x64 irq 1
[ 1.525287] serio: i8042 AUX port at 0x60,0x64 irq 12
[ 1.526035] input: AT Raw Set 2 keyboard as /devices/platform/i8042/serio0/input/input3
[ 21.927438] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input10

then, add the boot parameters i8042.direct and i8042.dumbkbd to /etc/default/grub. For example, run

sudo nano /etc/default/grub

Find the line that begins GRUB_CMDLINE_LINUX_DEFAULT= and edit it to include the new parameters, so that after your edit it looks something like

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.direct i8042.dumbkbd"

Save by pressing Ctrl+O, exit by pressing Ctrl+X, and run

sudo update-grub
