Hello, I also noticed that problem just after I'm start using Linux. Laptop is new, I bought it about 1 month ago. So there is problem with clean or reseat it byself and in the other hand when I will call to dell support with that they probably won't do anything because on Windows (with which laptop was sold) it works fine :/ Slawek W dniu 2014-09-03 10:01, Boy van Duuren napisał(a):

I have the same laptop, and kind of the same issue. My key doesn't get 'stuck', it just inputs the same character multiple times on one keypress. Same as you, this issue started the minute I changed from the default Windows installation to Arch Linux. I don't have this issue when using an external keyboard.

Hello, It happens on both: xsession and in console (login into some tty). Bios is up to date now and I didn't found any option which could be related to that in BIOS. W dniu 2014-09-03 12:17, Guus Snijders napisał(a):

Just a wild guess, search the bios for a keyboard repeat setting. I doubt that it's a hardware issue, because it stops when you hit any key.

Something you didn't mention; does this happen on the console, in an X session and/or both?

Hello, Thanks for info. Yesterday I downgrade bios to A08 and since then I have no any issue with keyboard so far. I hope that it really helps. I checked also changelog of A10 bios version and there is point: "Keyboard input improvement" - so this is probably "great" future --- Pozdrawiam Sławek Kapłoński slawek@kaplonski.pl Dnia wtorek, 9 września 2014 16:09:21 piszesz:

Actually, I've noticed this problem on my dell e7440 after updating the bios to A10. Unfortunately, I've not written the previous version I was using before (probably A08).

Hello,

Today I made one more test and work for a while in tty2 (not in xsession)

with

vim and there was no any issue with repeating. In similar time in xsession problem happend at least few times :/

Ok, so there is some hint that it is a problem with the keyboard settings. I have no experience there, but it shouldn't be that hard to find those. Note that DE's may override X settings, so try those first (things like kbd repeat, speed, etc). Mvg, Guus

Hello, Today I start to use more Windows 7 OS and I have no such problems but what is strange for me when I launched Lubuntu in virtualbox after few minutes of using it there is again same issue. So I'm almost sure that problem is somewhere in linux keyboard driver and how it works with keyboard in this laptop model but I have no idea how to fix this problem or how to get any details about it :/ Best regards Slawek Kaplonski slawek@kaplonski.pl -----Oryginalna wiadomość----- From: Sławek Kapłoński Sent: Saturday, September 06, 2014 10:54 PM To: General Discussion about Arch Linux Subject: Re: [arch-general] Dell latitude and keyboard problem

Hello, Thanks for Your answear. As I wrote, I start more using Windows last few days and in Windows 7 I installed virtualbox with Lubuntu 14.04. Today when I work on this Lubuntu in VM that issue happend again. In Windows it not happens any time. I have really no idea what could be a reason. It is also probably not problem with config because some time ago I was checking it on Ubuntu Live and that was also happend :/ Best regards Slawek Kaplonski slawek@kaplonski.pl W dniu 2014-09-09 o 09:00, Simon Hanna pisze:

It's not the cleanest approach, but if you cant find any other solution: Back everything up and restore the config files to default states.

A quick google for your notebook showed that it IS working using archlinux [1] [1] references a french site with some configurations for your notebook. You might wanna check this out too. [2]

In fact your notebook is even certified for ubuntu [3]

So it really looks like some config files are messed up... (Or since it's arch, newer packages break things. You might wanna try ubuntu from a usb drive just to be sure...)

Hello, Yes, few minutes ago I was downgrade bios to A08 (previous version from dell.com for this model) and I will see what will happend.

Hello!

Now this could be an evil and unsupported way, but try downgrading the bios to A09 or even A08 and test that. Also, now that this happens in a VM the issue could be raised to Dell support, as it should be a supported system.

Hello, Ok, thanks for info and help. If I will have other issue I will downgrade it to A05 but now it looks ok on A08 :) I'm really happy that I don't need windows and can normally work on Arch linux :) --- Pozdrawiam Sławek Kapłoński slawek@kaplonski.pl Dnia piątek, 12 września 2014 11:36:54 Hyacinthe Cartiaux pisze:

I've also reported the problem to Dell and the technician proposed me to downgrade to A05, the version certified by Canonical[0]. I hope it will solve my touchpad[1] and keyboard issues...

Btw, I've updated the wiki page for the e7440[2]
