Bug ID: 498956
Summary: Klipper applet interferes with Emacs
lost-selection-mode
Classification: Plasma
Product: plasmashell
Version: master
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Clipboard widget & pop-up
Assignee: plasma-b...@kde.org
Reporter: j...@keelhaul.me.uk
Target Milestone: 1.0
SUMMARY
GNU Emacs implements lost-selection-mode which, when enabled, causes the
selection within Emacs to be cleared if another application makes a primary
selection. IMHO this is good behaviour which I would like other applications
to also implement, but that is a personal preference and a separate issue. The
problem is that, when the Plasma clipboartd applet is active and this mode is
enabled, every time a selection is made in Emacs (by any means) somehow it is
immediately cleared. Disabling the clipboard applet restores Emacs to normal.
STEPS TO REPRODUCE
1. Enable the Klipper applet in Plasma, and start Emacs.
2. Ensure that Emacs' transient-mark-mode is enabled (this enables marked
region highlighting).
2. Make a text selection in Emacs by any means: by dragging the mouse,
Shift-arrow keys, or double or triple clicking.
3. Observe that the selection in Emacs is highlighted as expected, and that it
is added to Klipper's history.
4. Enable lost-selection-mode in Emacs.
5. Make a text selection again, and observe that as soon as the selection
action is finished (e.g. the mouse button is released at the end of a drag),
the highlighting disappears but the selected text is still added to Klipper's
history.
6. Without changing anything in Emacs, disable the Klipper applet. Observe
that selecting works and is highlighted as expected.
OBSERVED RESULT
In step 5 the selection highlighting in Emacs disappears.
EXPECTED RESULT
In step 5 the highlighting should remain.
ADDITIONAL INFORMATION
Klipper settings: Save history across desktop sessions = on
Keep selection and clipboard the same = on
Text selection = Always save in history
Non-text selection = Never save in history
