I just upgraded from 17.10 to 18.04 and noticed that right-clicking on my touch-pad got recognized as left-click.
I'm using a Dell Inspiron 15 (new) with a touch-pad that has two separate physical click-buttons underneath (pressing harder than touching). I don't know if they're both wired to the same event, though.
Before the upgrade I could cause a right-click by either tipping with two fingers OR clicking the right physical button. I use the latter for navigating in 3D-GUIs or drawing programs.
After the upgrade only the two-finger-tap works. I cannot perform click-right-and-drag actions any more. The one-finger-tap-and-move for dragging with the primary key still works, but there's no two-finger-tap-and-move for dragging/drawing with the secondary key (wouldn't be very ergonomic anyway). Two-finger-moves get recognized as scroll-event, which I like.
I found some advises to get the old behavior back:
- No secondary button (right click) on touchpad
- Dell Vostro 3568 model ubuntu 17.04 touch-pad left and right click behaving same way
- Right click not working on 18.04 Dell Inspiron 15 3000
- Touchpad right click doesn't work on touchpad, only the buttons above it. Thinkpad E480 Ubuntu 18.04 LTS
- Right click not working on Ubuntu 18.04
But neither the "Area"- nor "Fingers"-mode allow me to issue a right-click by using the lower right corner of the pad.
I haven't tried the command-line suggestions from the above links, as they weren't really explained or looked like whatever the
Tweaks-app does anyway.
