Plasma 5.1+ change date and clock font size
Edit:
sudo vi /usr/share/plasma/plasmoids/org.kde.plasma.digitalclock/contents/ui/DigitalClock.qml
Line 175:
Replace “? main.height * 0.56” with “? main.height * 0.40”
Please note that the rest of line 175 is excluded from this description to make it simpler.
Line 399: Replace “return 0.56 * main.height” with “return 0.40 * main.height”
Line 152: Replace “height: 0.8 * timeLabel.height” with “height: 1.0 * timeLabel.height”
May only need to change line 152.
Restart plasmashell with:
kquitapp5 plasmashell || killall plasmashell && kstart5 plasmashell
