Dell Latitude E7450: repeating keystrokes issue

[Peleg]

A brand new Dell Latitude E7450, with a fresh installation of Ubuntu 14.04.2. Sometimes a pressed key repeats until another key is pressed. This is presumably a BIOS bug.

Here's a discussion about it in Dell's community website (http://en.community.dell.com/support-forums/software-os/f/3525/p/19618638/20748484).

Since Canonical have certified this model (http://www.ubuntu.com/certification/hardware/201408-15385/), I have opened a launchpad question (https://answers.launchpad.net/ubuntu-certification/+question/264500) about it.

Since Dell works closely with Canonical on their products, I was wondering whether Canonical can get a formal reply from Dell about this issue (which apparently affects most if not all Linux distributions).

Status changed to 'Confirmed' because the bug affects multiple users.

Bios A03 seems to fix the problem. Until now, I can verify that. Other user reporting this issue also as fixed: http://en.community.dell.com/support-forums/software-os/f/3525/t/19618638

Hi Peleg and those who got affected by this issue,

according to the Dell Latitude E7450 A04 BIOS changelog [1], this BIOS update:
"Fixed the multiple characters displayed from a single keystroke when typing in Linux OS."

As this is BIOS related, I will close this bug with "Won't fix", please give that BIOS update a try, and re-open a bug if this issue still exists with BIOS revision A04.

Thanks!

I can confirm - I had this issue with BIOS A02 with Ubuntu 15.04 (Vivid Vervet) and just upgraded it to A06 - keystrokes issue disappeared since then.
