lost scrollbar controls in 10.x

Postby techsavvy » 2019-07-26 00:15

The <>^ and "down" scrollbar controls are missing from all plasma desktop applications after upgrade to Debian 10.x. How to recover such controls, please?

Are you sure they aren't just "hidden"? That's the new Gnome "thing". The default Devuan theme has restored them.

My KDE Plasma desktop has scrollbars visible, just not the controls at the top, bottom of vertical, or left, right of horizontal scrollbars. This only occurred after an upgrade to Debian 10.

I attempted to attach an image, but apparently am not allowed to do so for some reason.

Try a different theme. Or modify the one you're using.

Would you suggest a theme that offers scrollbar controls for a Plasma desktop, please? None of those I've tried offer such scrollbar controls, and the descriptions of the themes are inadequate. The small images of them are overwhelmed by the backgrounds.

I modified "Breeze" parameters and now have the scrollbar controls in the konsole terminal and dolphin, but other windows such as gedit, firefox and thunderbird still have the controls missing.

I don't use any Qt themes, sorry.

Funny I've used Plasma 5 for several years and never noticed it doesn't have scroll arrows. Mouse wheel for vertical and dragging for horizontal scroll has always seemed easy
For Plasma theme it can be changed in System Settings > Application Style > Widget Style > Configure > Scrollbars.

Gedit, Firefox and Thunderbird are GTK applications so you need to edit GTK themes. For GTK3, create or edit ~/.config/gtk-3.0/gtk.css
And add:
Code: Select all
.scrollbar {
  -GtkScrollbar-has-backward-stepper: true;
  -GtkScrollbar-has-forward-stepper: true;
  }


From https://unix.stackexchange.com/question ... croll-bars . Take special note of the comment about the leading dot, it may not be required for GTK3.20+

For GTK2, I don't know. And I also don't know why you'd use Gedit in KDE when you have Kate or Kwrite.
