I am an very familiarized Plasma user, used in all my Distro Hopping journey, but when i went to Manjaro ISO site, i only seed the GNOME opition. Then i put it into my ventoy USB but i thought:
Why?
. can the DEVs / some person explain why this? Obs: ik you can put plasma manually, but im kinda lazy.
Look again.
There is also Plasma and XFCE among the official editions.
Community editions are Cinnamon, i3, and Sway listed right below.
How do you only see Gnome? Where?
I remember when i was putting the iso in my ventoy, but i only saw gnome. Idk why and how, this may be my browser / site issue.
The FIRST Official Image I see is KDE Plasma (the Bleeding Edge option)
The SECOND Official Image I see is Xfce (the rock solid option).
The THIRD is Gnome.
Before muting this, i would never choose GNOME as my default if i have Plasma. Sorry in advance for creating this polemic post. Please stop bumping this topic to top and correcting me. i would like to adm close this, as i cannot due to Trust Levels.
No need to apologize. All of us miss things sometimes!
