Since I don't really like any splash screen and I didn't find such info for GIMP, how can I disable the GIMP version 2.8 splash screen?
sudo sed -i 's/^Exec=[^ ]*/& --no-splash/' /usr/share/applications/gimp.desktop
The sed script inserts the
--no-splash flag right after the executable's name, this way disabling the splash screen.
sudo sed 's/^Exec=[^ ]*/& -s/' /usr/share/applications/gimp.desktop
