Keyboard function lost when re-connecting keyboard-cover or suspending; touchpad remains functional
I have been using a Dell Latitude 7212 Rugged Extreme tablet with Win10 for a while, but decided I would like to move to Ubuntu and installed 18.04 Bionic. Everything's working great, with the exception of the keyboard cover that ships with the device. The keyboard cover interfaces with the tablet through a connection I can't identify on the bottom of the tablet - it's not USB.
During the live install, as well as right after booting, it works flawlessly - it is automatically recognized, I can use it to decrypt my partition and login. However, if I disconnect and reconnect the keyboard, or suspend the tablet and wake it up again, only the touchpad remains functional - the keystrokes are completely ignored. To use the tablet, I have to force-reboot it every time it goes to sleep or I close it or re-connect the cover.
Here's what I could find in the dmesg regarding the keyboard:
[ 6.803686] i8042: PNP: PS/2 Controller [PNP0303:PS2K,PNP0f13:PS2M] at 0x60,0x64 irq 1,12
[ 6.804338] i8042: Warning: Keylock active
[ 6.805971] serio: i8042 KBD port at 0x60,0x64 irq 1
[ 6.805990] serio: i8042 AUX port at 0x60,0x64 irq 12
[ 6.809712] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input4
[ 12.184527] input: ImPS/2 Generic Wheel Mouse as /devices/platform/i8042/serio1/input/input6
What I've tried:
Adding GRUB_CMDLINE_LINUX="atkbd.reset=1 i8042.nomux=1 i8042.reset=1 i8042.nopnp=1 i8042.dumbkbd=1" to /etc/default/grub as suggested here lead to me having to re-install Ubuntu because the keyboard inputs were mis-interpreted by the decryption utility, rendering me unable to boot.
Doing sudo apt-get install xserver-xorg-input-all as suggested here to no effect.
Please tell me what I can do to help you diagnose this problem - I'd love to use Ubuntu as my main OS.
