[Ubuntu-x-swat] [Bug 1775016] Re: [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 simila
To be clear, I wish to send this video. It happens unpredictably. Even after a reformat it still happens like this. So, is it possible this is a bug or this is more likely a hardware issue rather than a bug or is it possibly both? (Because of necessity, I had to change the laptop keyboard for the replacement English keyboard instead. And, I'm using it now as of this writing.

I don't quite follow. Do you still experience the original bug at all?

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-X, which is subscribed to xorg-server in 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.

Well, I just applied a firmware upgrade from A08 (very first firmware revision of the Dell Latitude E6420) to A25 (released just this year, 27 March 2018). SOURCE: https://www.dell.com/support/home/us/en/19/drivers/driversdetails?driverId=JP0YK I am yet to see the results of the firmware upgrade. This download was marked: "Urgent" But I think it is leaning on the good side since this addresses: CVE-2017-5715 which says "Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis." SOURCE: https://www.cvedetails.com/cve/CVE-2017-5715/ In other words, Spectre. This Spectre problem is being patched with this firmware. And as of this forum post, I typed this using my laptop keyboard.

This just in, given that I currently use Linux 4.10.17-041017-generic (x86_64), here is my situation as of now: 1. I was in Twitter. 2. I was trying to type my tweet 3.

Great news about downgrading the kernel. Next, please find the closest two kernel versions where one works and the other doesn't.
