Description Madison Kelly 2019-11-08 02:22:59 UTC

Description of problem:

If I highlight text (from gnome-terminal, chrome, etc) and try to middle-click to paste the highlighted text to kate, nothing happens. This worked before I upgraded from Fedora 30 (kate v. 19.04.2). After I updated to Fedora 31 (kate v. 19.08.2), it stopped working.

Thinking it might have been a problem with the update, I booted the live USB image. I installed kate there, and the issue remains. So I don't believe it is related to profile or update process itself.

1. Install 'kate' and 'kate-plugings'
2. Highlight something, switch to kate, middle click

Actual results:

Can't highlight -> middle-click


Expected results:

Can highlight -> middle-click

Further testing shows this is related to Wayland. If I log into gnome under Xorg, middle-click pasting works fine. When logged into Gnome (alone, at the login screen), it doesn't work. I verified the window manager with 'loginctl show-session X -p Type'.

Comment 2 Madison Kelly 2019-11-08 03:23:14 UTC

Further info;

I installed plasma-workspace-wayland kwin-wayland. When I log in with 'Plasma', it works. loginctl shows it's still Wayland. However, when I log in with "Plasma Wayland", where loginctl shows it's still wayland, it doesn't work. 

So to summarize; 

* Middle-click works with Xorg and Plasma
* Middle-click does NOT work with Gnome and Plasma Wayland

Comment 3 Madison Kelly 2019-11-08 03:29:00 UTC

Another note; I used gnome-tweak-tool to check that middle-click paste was enabled, and it was. I tried disabling and then re-enabling it without success.

Comment 4 Rex Dieter 2019-11-08 22:58:26 UTC

Indeed, Qt5 does not yet support gnome's primary selection protocol yet,
