I want to disable the default zorin 17 screenshot preview thingy.
I'm using flameshot for taking screenshots and the new preview thing keeps asking for permission [ share button ]
plus unlike flameshot it saves all the screenshots to Pictures which i don't want
Personally I prefer Spectacle, but you might want to give Shutter a try which is available in Software. I recently discovered another screen capture application while playing with NiceC0re, HotShots.
I think I simply uninstalled screenshot from Software on Z16.3 when it started misbehaving. Like you I have converted to Flameshot with no issues by comparison.
In Zorin OS 17, the desktop defaults to Wayland. Gnome, unwilling to deviate from the push to Wayland, was unable to patch gnome-screenshot tool to be compatible with Wayland.
So, they integrated the screenshot tool into the Gnome shell, making the application no longer modular and less applicable to open source access.
In Ubuntu 22.04 and newer, the new Gnome screenshot tool is baked into gnome-shell. It's not a separate package anymore. It cannot be removed separately from gnome-shell, and there is no setting to disable it . If you don't want it, then simply ignore the built-in feature and use your preferred application instead.
