Well, Gnome + Mutter are not praised for their multi-monitors support either.
Hi, I have the exact same problem.
I’m trying the different flavors of ubuntu on a spare laptop and I started with Budgie. When I connect my external monitor, the windows snap to the right third of the screen. When maximizing a window, it snaps to the right third. I can only use the left part of the monitor if I drag the left window edge. I have the problem both via usb-C and HDMI. I tested on Ubuntu budgie 25.10 and 24.04 LTS (via live usb). The laptop does NOT have an nvidia gpu.
Thanks upfront!
Try moving your two displays around on budgie-control-center - displays. Often changing the orientation/ changing which one is the primary makes thing work.
Indeed, two different things make it work:
- positioning the external screen below the laptop screen. This is very confusing though, because physically it is above
- making the external monitor the primary (while keeping it above).
Is this a bug that will be fixed in the next LTS? Does it need reporting or upvoting somewhere?
Welcome to the weird world of the xserver. The next LTS is wayland based. So very different multimonitor support.
In some setups, you have to make sure monitors align in corners - i.e. on a top/bottom setup, dont make the smaller display in the middle of the larger display. Snap them to a corner.
