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.
