Keyboard and touchpad stop working randomly

[anon89812132]

Hello,

Try this and see if that solves the issue

Touchpad sometimes not working

UPDATE: problem fixed by blacklisting psmouse module. I noticed, that xinput list returned correctly dell device and also incorrectly PS/2 mouse. Unloading psmouse kernel module from running system basically disabled touchpad. The solution was creating /etc/modprobe.d/blacklist.conf file and adding blacklist psmouse line.
