Bug ID: 498725
Summary: Touchpad/Touchscreen 3 and 4 finger gestures are
inconsistent
Classification: Plasma
Product: kwin
Version: 6.2.90
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Gestures
Assignee: kwin-bugs-n...@kde.org
Reporter: cameronsmith...@gmail.com
Target Milestone: ---
SUMMARY
The 3 and 4 finger gestures implemented by kwin are inconsistent across
touchpads and touchscreens. These should be largely the same.
Touchpad:
3 AND 4 fingers left gesture: move to left virtual desktop (if present)
3 AND 4 fingers right gesture: move to right virtual desktop (if present)
3 finger up gesture: move to above virtual desktop (if present)
3 finger down gesture: move to below virtual desktop (if present)
4 finger up gesture: show overview/cycle forward (default view, overview, grid
view)
4 finger down gesture: show grid view/cycle backward (default view, overview,
grid view)
Touchscreen:
3 finger left gesture: move to left virtual desktop (if present)
3 finger right gesture: move to right virtual desktop (if present)
3 finger up gesture: show overview/cycle forward (default view, overview, grid
view)
3 finger down gesture: show grid view/cycle backward (default view, overview,
grid view)
4 finger gestures: not implemented (!)
This introduces significant problems for touch users with at least 2 rows of
virtual desktops, as they cannot switch to above or below rows of virtual
desktops without using 3/4 finger gestures alone!
STEPS TO REPRODUCE
1. Have a device with both a touchscreen and a touchpad (touchscreen laptop)
2. Ensure at least 2 rows of virtual desktops are enabled
3. Try to use 3/4 finger gestures on touchscreen only to switch to higher/lower
virtual desktop rows
OBSERVED RESULT
Nothing happens (4 finger up/down gestures), or overview/grid view is toggled
(3 finger up/down gestures).
EXPECTED RESULT
Toggle overview/grid view (4 finger up/down gestures), or move up/down virtual
desktop grid (3 finger up/down gestures).
Also expect 4 finger left/right gestures to switch virtual desktops (I don't
think this is an optimal bind, but we should strive for consistency until a
better use is decided for them).
OS VERSIONS
Arch Linux, KDE Plasma
KDE Plasma Version: 6.2.90
KDE Frameworks Version: 6.10.0
Qt Version: 6.9.0
ADDITIONAL INFORMATION
I don't really like how 3/4 finger left/right gestures do the same thing on a
touchpad, and I suspect this will be changed in the future from looking at some
other bug reports/discussions (https://invent.kde.org/plasma/kwin/-/issues/59,
https://invent.kde.org/plasma/kwin/-/issues/188, etc). This bug should not
attempt to address these issues as well, rather just make the gestures
consistent across touchpad/touchscreen.
