It is possible, but not recommended by the devs team, last time I heard.

Oh ok, I figured as much but it never hurts to ask, Thanks!

    I'm not entirely sure where people got the impression that it isn't recommended, maybe I need to ensure the entire team is on the same page on this matter to ensure they're communicating the nuanced, but accurate position.

    Co-installing GTK based desktops and their related stacks is typically fine. So you can co-install Budgie and GNOME, Budgie and MATE, and MATE and GNOME. The only thing to look out for here is GNOME Shell as it requires GDM as its display manager, as we note in our Desktop Environments page, instead of lightdm. You can't use GNOME Shell without GDM.

    Budgie and GNOME utilize almost entirely the same stack at this moment in time (Mutter, GNOME Settings Daemon, GNOME or GTK apps) and aside from ensuring you set your default applications correctly when using MATE, using that and another GTK-based desktop is fine too.

    What is not recommended is mixing Plasma Desktop and a GTK-based desktop. You're mixing completely different stacks on different toolkits.

      I think when posters have a hard time making it work with solus and another distro, solus/W10, solus mate/solus budgie, solus budgie/solus plasma---that's it's an oft-spouted line. So I also accepted it as conventional wisdom like elfprince did. Nice to know better.
      AFAIK, Solus does have an official position on W10&Solus side-by-side which is basically "don't recommend it"---right?

            JoshStrobl Well, I admit I did not expect that! Thank you for the information, How would I go about installing MATE alongside Budgie properly?

                V1T4MiN Unless I''m misunderstanding something it should be as simple as just installing it through your preferred terminal (sudo eopkg install -c desktop.mate). There shouldn't be any special things you need to do. The only thing you would need to do something extra for is if you were installing GNOME in which case you would need to disable or uninstall LightDM to be replaced by GDM.

                  craigtoyoracer Question, I run Budgie and would like to use Krita and digiKam. Is this going to lead to possible conflicts ?

                  You can install KDE and Qt5 applications alongside GTK-based desktop environments just fine.

                  Our documentation will enable you to install any software in the specific component as mentioned by @Max_The_Bear. If may not install all of the "default" applications that you would get by using a Solus MATE image however, so expect that in some places it'll use the defaults from your original installation.

                  We have a side-by-side installation option that is specifically designed for dual booting Windows and Solus. However, as it normal convention when installing any Linux-based operating system alongside Windows, the general consensus is to free up disk space via Windows' own tools first (shrinking partitions using Disk Manager) than letting installers do it, alongside having a dedicated ESP for Solus if you intend on having them be co-installed. Windows has been known to wipe an ESP and replace it with its own new contents during large Windows updates.

                          JoshStrobl Thank you. I knew there was a tutorial. I would never do it though. Separate drives for me!

                            Ok, Thanks, I will try that today!

                            It Worked! I now have Budgie and MATE living in harmony on my system 😃
                            Thanks & Regards
