Public bug reported:
I bought the DELL 16" 5640 laptop, preinstalled with Ubuntu. Canonical
has even an additional repo for this laptop, so I consider this to be
YOUR product as much as DELL's. I know you have a business pact with
them and you support these laptops with a special repo, and because of
that, I put the blame both on DELL and on Canonical alike.
My problem is that there is no palm rejection on this laptop. There was
no information that this is not supported, and in 2025, this is a
feature that is normal to be part of any touchpad/OS.
I've installed also Arch to see if newer versions of libinput do add
palm rejection, but no, it doesn't. I also did a bug report at
libinput's gitlab, but I feel that this is something that Canonical
should have taken care of when the laptop was released.
As you can see in my picture, this is the normal way of placing my hands
on the laptop (to both type at a moment's notice, and to stabilize the
laptop on my lap), and ALL laptops by Apple, and many x86 laptops
recognize that the edges don't count (basically they implement palm
rejection). With this instead, I have the mouse cursor moving, stopping,
moving etc, because the touchpad can't decide which touch has priority.
It's the most annoying usage on a laptop I've had in a long time. I'm
hitting this ALL the time.
Honestly, I'm angry. I just paid 950 euros to buy this Canonical-
supported laptop, and I find that the touchpad experience is something
out of 2008. And no, that's not a valid reason to return it, the DELL
reseller I bought it from in Greece would never accept that as a reason.
So I'm stuck with using a freaking mouse with it. Unacceptable.
