Sorry if I missed the point all this whole time. But, this is just in. I saw a warning in the BIOS settings when switching between AHCI and RAID. There was a warning that actually threatens the installation that says:
"SATA Operation is being changed! Attention! Changing this setting may prevent your operating system from booting or require a reinstall. Attention! The E-Module and other eSATA devices only function in AHCI or Raid On mode. Are you sure you would like to continue?" Only to find out later, I scouted through the "Disks" utility and it says at the Edit Partition settings (Partition Type) is that the bootable Linux partition is actually "Linux (0x83)" and not "Linux RAID auto (0xfd)" and then I changed it to "Linux RAID auto (0xfd)". I just think, not really seeing yet, but I just think that this warning in the BIOS which says "Attention! The E-Module and other eSATA devices only function in AHCI or Raid On mode." actually led me to this workaround that could drive the keyboard problem away here in 18.04 Ubuntu base. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1775016 Title: [Dell Latitude E6420] Ubuntu/Xubuntu 18.04 bug: Keyboard stops working in the middle of typing when running firefox and when running the terminal (sudo su) and similar programs until reboot.
