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? Mvg, Guus

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 :/ -- Pozdrawiam, Sławek Kapłoński slawek@kaplonski.pl -- Klucz GPG można pobrać ze strony: http://kaplonski.pl/files/slawek_kaplonski.pub.key -- My public GPG key can be downloaded from: http://kaplonski.pl/files/slawek_kaplonski.pub.key Dnia środa, 3 września 2014 12:17:03 Guus Snijders pisze:

Hello, Yesterday I received new keyboard from dell and I replace it but that not helps me - In Linux I still have same issue sometimes. I have no idea what settings could be responsible for that or what should I change. My xserver keyboard settings are: setxkbmap -print -verbose 10 Setting verbose level to 10 locale is C Trying to load rules file ./rules/evdev... Trying to load rules file /usr/share/X11/xkb/rules/evdev... Success. Applied rules from evdev: rules: evdev model: latitude layout: pl Trying to build keymap using the following components: keycodes: evdev+aliases(qwerty) types: complete compat: complete symbols: pc+pl+inet(evdev) geometry: dell(latitude) xkb_keymap { xkb_keycodes { include "evdev+aliases(qwerty)" }; xkb_types { include "complete" }; xkb_compat { include "complete" }; xkb_symbols { include "pc+pl+inet(evdev)" }; xkb_geometry { include "dell(latitude)" }; }; Only workaround which I know is to disable repeating keypress but that is definitly not god for me :/ Maybe You have some idea what should I change or what can be wrong here? -- Pozdrawiam, Sławek Kapłoński slawek@kaplonski.pl -- Klucz GPG można pobrać ze strony: http://kaplonski.pl/files/slawek_kaplonski.pub.key -- My public GPG key can be downloaded from: http://kaplonski.pl/files/slawek_kaplonski.pub.key Dnia czwartek, 4 września 2014 09:02:58 Guus Snijders pisze:

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).

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.

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:

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.

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). 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.

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.

Thanks for your feedback.

I reported it to dell support now and I got new keyboard from dell but replacement didn't help me :/

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...
