I’ve had this problem with the new LEAP 15.2 and Tumbleweed. I’ve verified by re-installing multiple times.
I installed all DESKTOPs, i.e. GNOME, Classic, SLE, MATE, XFCE, etc.
After installation I tried MATE, which so far is my favorite; It worked just fine.
Then I logged out and logged back in with XFCE; Fine as well.
I then tried GNOME to see what it looked like, although I do not like it. (I tried X and Wayland)
When I logged out and tried to log back in to MATE, my panel was missing the Advanced Menu; I tried adding it, without success. I can add MATE Menu.
After a couple of attempts to switch between desktops, the system starting freezing after the boot loader.
I’ve repeated the process and it appears to have something to do with GNOME. I finally installed MATE and XFCE and all is fine.
Well, I was wrong all along. I left my system overnight running the MATE desktop.
This morning, the Advanced Mate Menu was gone. I cannot add it as before. So this appears to be strictly a MATE issue.
I am very frustrated. Is MATE no longer an active Desktop on OpenSuSE? I’pve tried going to the MATE wiki, following to the forums, nothing comes up. Has anyone here heard what is going on?
Mate is supported in openSUSE. I tested it myself though I had not issues but then I did not install other desktops parallel to it.
The only thing that one of the wiki pages describes is that Mate might not be thoroughly tested like Plasma, Gnome and Xfce.
