+ | ===== 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 | ||

+ | ===== 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+ | Subversive is no longer maintained, don't use it! | ||

+ | ==== 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. | Using KDE 4.11 (Kubuntu 14.04) the whole workspace freezes when debugging GUIs, e.g. Java FX.
