-====== KDE 5 / Kubuntu Tipps & Tricks ======
+====== Kubuntu Wrestling ======
+===== Menu =====
+Instead of using kmenueditor a quick way to add new entries to the start menu is by creating a .desktop file here:
+<code>
+~/.local/share/applications/
+</code>
+E.g.
+<file text anaconda-navigator.desktop>
+[Desktop Entry]
+Name=Anaconda
+Comment=anaconda-navigator
+Exec=/usr/bin/env PATH=/home/mstraub/anaconda3/bin/:$PATH /home/mstraub/anaconda3/bin/anaconda-navigator
+Icon=/home/mstraub/anaconda3/lib/python3.7/site-packages/anaconda_navigator/static/images/logos/continuum_twitter.jpg
+Terminal=false
+Type=Application
+StartupNotify=true
+</file>
+===== Kubuntu 18.04 Troubleshooting =====
+Solving my problems with a Lenovo Thinkpad T450s:
+I ended up putting the following scripts in ''/lib/systemd/system-sleep''.
+This script fixes that touchpad scrolling with a two finger gesture does not work anymore after resume:
+<file bash fix-touchpad.sh>
+#!/bin/bash
+case "$1" in
+    post)
+        modprobe -r psmouse
+        modprobe psmouse
+        echo "modprobe script finished @ `date`" >> /tmp/modprobescript
+        ;;
+esac
+</file>
+And this script is an ugly workaround for notifications and global shortcuts not working anymore after resume (see also https://bugs.kde.org/show_bug.cgi?id=396682)
+<file bash fix-global-shortcuts-and-notifications.sh>
+#!/bin/bash
+sleep 6
+export DISPLAY=:0
+sudo -u markus kcmshell5 khotkeys &
+sleep 1
+killall kcmshell5
+</file>
+===== Inkscape Tooltips =====
+To avoid nearly unreadable (white on white) tooltips in Inkscape disable ''Apply colors to non-Qt applications'' in the KDE System Settings under Colors.
+https://askubuntu.com/questions/725642/inkscape-tooltips-unreadable
+===== Eclipse & SVN =====
+Using Eclipse 2018.09 and Kubuntu 18.04:
+Subclipse by default uses JavaHL - this does not work well, for each svn update it takes Gigabytes of RAM and a long time. What works: switch to the pure Java implementation (SVNKit) in Preferences > SVN!
+Subversive is no longer maintained, don't use it!

-===== KDE 4 freezes in Debugging GUIs =====
+===== KDE 4 & Eclipse problems =====
+==== Freezes when Debugging GUIs ====
 Using KDE 4.11 (Kubuntu 14.04) the whole workspace freezes when debugging GUIs, e.g. Java FX. Only switching to the console and killing the started program makes the desktop responsive again.
