Public bug reported:
Although I'm able set resolution to 1920x1080, upon doing so, the
touchpad on my Logitech K400 Wireless keyboard/touchpad becomes so slow
and laggy, that I cannot enjoy the better looking resolution.
I've tried adjusting the touchpad speed to its max setting in GNOME3's
settings panel, but this has an almost unnoticeable influence.
When I set resolution to 1440x900, the same touchpad is very fast and
responsive.
The bug is that nothing in the touchpad settings addresses this issue: I
either have to endure less than optimal resolution, or endure less than
optimal touchpad sensitivity.
I'm currently installing this:
sudo apt install kde-plasma-desktop
I'll report back soon as to notify whether or not this allows me to have
decent touchpad sensitivity at a 1920x1080 resolution.
