KDE is amazing and I realize a lot of it is volunteer work. Therefore, please don’t take this as a complaint, but rather a hope that it’ll work better and an attempt to point out something that could be useful to address.
It seems like touch isn’t working well with KDE, with the severe impact issues I’ve ran into being:
- Tapping the manual on-screen keyboard toggle sometimes simply doesn’t seem t o work 499522 – "Input method" toggle doesn't bring up maliit osk, touch keyboard seems inaccessible meaning it’s not possible to type at all for some apps that don’t bring it up themselves.
- Lock screen may break with touch keyboard and leave user stranded: 489671 – Time-based lock screen with maliit enabled has broken password confirm button sometimes
- In many different KDE applications, a simple touch scroll will bring up the on-screen keyboard even after it was just toggled away, making it infeasible to fully see window contents using the entire screen when scrolling: 489822 – Possible underlying Qt or Plasma or ...? bug causing keyboard to come up from touch scroll
Less severe ones that might nevertheless probably be frequently encountered by touch exclusive users:
- Open/Save file dialogs appear to have no touch scroll: 496023 – Open/save dialog file listing has no touch scroll, making it seemingly near impossible to navigate larger folders
- Windows will shrink to make room for the touch keyboard but then when the keyboard is hidden to show more window contents, often the window won’t expand again even if maximized: 498221 – Resizable windows under Wayland aren't automatically shrunk to avoid having parts cut off like they are under X11
- The touch keyboard seems to lack a way to access some essential keys for power users, like CTRL, Escape, Tab, and arrow keys: Adding terminal layout? · Issue #20 · maliit/keyboard · GitHub
I hope this list is useful for somebody who might be looking into making touch work nicely with KDE. If not then I apologize for taking up anyone’s time.
