Oh, I just forgot to mention : Ubuntu is in Feature Freeze now. The 3.31.90 GNOME packages that made it into the repos will be going to be updated to 2.32 or 2.32.1 though.
LibreOffice is on 6.2.1rc1 and will certainly be upgraded to 6.2.1 or even 6.2.2 for Ubuntu 19.04.
There will probably be more top bar states depending on the background just like in Elementary. When that pull request is accepted, it will be interesting to see if Ubuntu-Dock should follow to adapt to these new states.
Get yourself together, please. In one message you say you don’t want Ubuntu to use dash-to-panel, in another one you say the opposite. It is extremely hard to understand the points of your messages.
There’s no such thing as Wayland yet, is there? Only an X server running on top of wayland. It should be Ubuntu on Xwayland, rather than Ubuntu on Wayland, right?
There is a Wayland session. Even if XWayland is still started as well at the moment. There was a lot of hassle to separate the codepaths this cycle to make XWayland start up just on demand. There is even a patchset by Carlos Garnacho ready to be merged, but I think that it is too close to 3.32 already.
XWayland is just a thing of the Wayland session. In an Xorg session there would be no need for XWayland.
I looked in /usr, but can’t find much. only links to 2 apps.
Finally, I stopped Ubuntu on Wayland from showing up at login. Most apps don’t work in that anyway.
