Hmm, my plasma startup first time after 202 items updated, was long enough that I was almost convinced the machine was broken. I haven't restarted again to see if it was a one time thing or what. I'll logout and try budgie too in a few minutes.
Otherwise, all seems well so far.
Edit: Nope, Budgie started swiftly. And the next login to Plasma was swift, so apparently something that was a one-time task.

    adapta theme is a bit broken https://i.imgur.com/Mn72HSY.png 🙁 (i know thats not solus' fault, and that its unmaintained)
    and i dont like plata, so reverted to good old arc which seems fine

    @JoshStrobl it seems the top icons thing is fixed in 3.32.2, i forgot ,what is the solus policy on such incremental updates? will we have them at some stage or are we sticking with 3.32.1 until 3.34.1 (or 3.36.1 or whatever) ?

      Lucien_Lachance We'll be upgrading to GNOME Shell 3.32.2 (and all the other point releases for various GNOME software) when it's released. Right now they're still on GNOME Shell 3.32.1. That being said, I'll look into how trivial it'll be to backport that to our GNOME Shell for the time-being. We only hold off entire GNOME Stack upgrades for the larger updates / new series (so like 3.34).

      Edit: I've updated the original post to have notes about Adapta and more information about Top Icons.

        @Lucien_Lachance Please re-enable Top Icon Plus extension, run the following command, and reboot. Let me know if it resolves your CPU usage issue. If so, I'll push it to stable.

        sudo eopkg install https://packages.getsol.us/unstable/g/gnome-shell/gnome-shell-3.32.1-41-1-x86_64.eopkg

          I did find one thing broken in Plasma, it doesn't find my sound devices at all, whereas they're fine in Budgie in the same install.

          Device-1: AMD Baffin HDMI/DP Audio [Radeon RX 550 640SP / RX 560/560X]
          driver: snd_hda_intel
          Device-2: AMD Family 17h HD Audio driver: snd_hda_intel
          Sound Server: ALSA v: k5.0.7-114.current

          I had 174(!) packages--like a fresh install!
          But went smooth.

          I am only responding to this post to say noticed I no changes in Budgie. All seems fantastic as usual. I'm noting no font or icon changes or anything else. Graci.

          edit: typo

            there seems to be a small graphical bug, maybe its well known i dont know, when rclicking a folder in nautilus on solus gnome, happens with arc, adapta, plata and adwaita, those are the ones ive tested

              After update, I am booting straight to TTY (not getting the desktop). I suspect it has something to do with the NVIDIA driver, but I do not know what to do - I have nvidia-glx-driver-current installed.

                beerminer I would make sure you've done a full upgrade and don't have broken packages. Run:

                sudo eopkg check | grep Broken | awk '{print $4}' | xargs sudo eopkg it --reinstall

                We have not updated the kernels during this sync cycle, as that is slated for tomorrow by @DataDrake

                    1. What desktop environment are you using and with what login manager? (For example, Budgie and MATE default to LightDM+slick-greeter, whereas GNOME defaults to GDM, but you can also use GDM with Budgie or MATE).
                    2. What graphics card?
                    3. Could you run sudo journalctl -b -e (basically means "show me the system log for this boot, move the pager to the end of the log) and see if you see any greeter, X11, or desktop failures?
                    4. Do you have automatic login enabled?

                        I have Solus installed on a 128GB SSD, but it reports that it has a 640GB disk

                          there is also an issue on gnome with apps that are minimized when doing alt-f2+r, they become like ghost apps, some transparent and some not, they cant be clicked and only revert to normal after selecting them in alt-tab or by min/maxing them by other means. big screenshot
