Hi, As I've mentioned in my previous comment, the key press and release events go through the kernel and are received by the X Server and the X Server understands the events well. So this seems not to be a kernel issue at all. Am I right? If so, this bug could well have been closed as invalid instead of expired.
Also, as I've alredy mentioned in the report (the first comment), the issue wasn't present on Debian, so this could be another hint that this has nothing to do with the kernel. Besides, this was the reason why I've reported this bug here, in the Ubuntu bug tracker. I could report the bug for a different component (KDE maybe?), other than linux, but I don't wan't it again to be reported against wrong component. And my knowledge in this field isn't broad enough to guess what component it could be. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1015496 Title: Disable-touchpad key does not work on Dell Vostro V3450 Status in “linux” package in Ubuntu: Expired Bug description: Hello, The problem is that the 'disable touchpad' function key does not work in Ubuntu for Dell Vostro V3450 (please note the V before the number - as far as I know, the Vostro without V before the number is another model from Dell). I've noticed this already in the previous Ubuntu release (11.10) but thought it'll be fixed by now. After upgrade to 12.04 nothing has changed. I've, of course, searched for similar bugs on launchpad, but I believe they are not the same issues as mine. The problem is similar to bug #753641, but that one has been marked as a duplicate of already resolved bug #550625 and my issue is not resolved. Also bug #760142 is similar, but I don't think my touchpad uses the ALPS driver. On my V3450 the 'disable touchpad' key is Fn+F3 combination. Pressing the combination doesn't disable the touchpad in Ubuntu. It also doesn't display any pop-up on the screen (as photonic wrote in a comment to bug #753641, in his case "a notification pops up displaying graphic of a crossed-out touchpad" - it doesn't happen on my system). However, I'm sure that the laptop's hardware does inform the system when the combination has been pressed - in my laptop I have an orange led placed between the touchpad and the keyboard. When I press Fn+F3 the LED turns on, suggesting that the touchpad is disabled. When I press Fn+F3 again, the LED is being turned off. Another hint - after I bought the laptop I've installed Debian wheezy/testing on it and there the Fn+F3 combination worked as expected.
