I had enabled those options in the file before I reverted them back to show you my desktop files.
Your method of adding the following files to:
/usr/share/gnome/autostart works!
Code:
[Desktop Entry]
Type=Application
Name=Gnome Screensaver
Exec=/usr/bin/gnome-screensaver
[Desktop Entry]
Type=Application
Name=Redshift
Exec=/usr/bin/redshift-gtk
I'm not sure what's up with the existing desktop files and the ~/.config/autostart but this works for me, since it's my machine. Thank you so much!
