7th. Testing


I'm glad I find out that Unity7 works well on my testing at 19.10. Working Unity desktop should looks like 16.04 once again but with 19.10 wallpaper on 19.10. Precisely, this means you should see the Dash menu, vertical panel, HUD, and Alt+Tab switcher all being transparent and not opaque.

A working Unity7 desktop on 19.10 Eoan Ermine looks like below with smooth drop shadow under black panel, window border, and icons:


Alt+Tab switcher looks nice with transparency:


Launcher, the vertical panel, looks transparent against windows below it:


Global Menu and Head's Up Display work with menubar-styled apps like Firefox, Rhythmbox, LibreOffice, GIMP, Inkscape, etc.:


 

Workspace switcher works well with animation:


Shortcomings and My Gratitude


I am aware that this tutorial doesn't include LightDM as I failed to enable it as default DM on this 19.10. So here I use built-in GDM3 instead. I am also aware that LightDM appearance is more suitable to Unity rather than GDM3's, but at the moment I don't know how to make it works. Do you know some workaround? Please add it on comment. Thanks!

One more shortcoming is that Unity System Settings still read OS name as 19.04 (Disco Dingo) and not 19.10 (Eoan Ermine). I guess this is only because Eoan at the time I write this article is still in development stage and I believe this will be corrected once it officially released.

Finally, I would love to say huge thanks to Unity7 Maintainer Team leaded by Dale and Khurshid and also good luck for you using Unity. Happy working!
