I can launch opera manually from the CLI with smooth scrolling enabled like so:
/usr/bin/opera --enable-smooth-scrolling
However, if I launch opera through synapse or the unity launcher, opera will launch without smooth scrolling, which is much worse. How can I get Ubuntu to open opera with this command by default instead of just executing /usr/bin/opera?
By using the "No new software method" answer from How do I add an application to the dash? I was able to create an application called "Opera-new" just by creating a file at: $HOME/.local/share/applications/opera.desktop with the following contents:
[Desktop Entry]
Name=Opera-new
Comment=
Exec=opera --new-window --enable-smooth-scrolling %U
Icon=opera
Terminal=false
Type=Application
StartupNotify=true
I was surprised that even the icon showed up correctly.
Unfortunately, changing Opera-new to just Opera in the config didn't have the desired result, so I had to come up with an alternative name for launching the application.
