--- Quote ---If not, you need to first rebuild your IDE with -gw (in Tools > Configure build Lazarus :: in the memo "Custom options")
--- End quote ---
When I try to rebuild with -gw in Tools Lazarus disappears from the screen but the process is still running in Terminal.
--- Quote ---Also: Do you get the error if you choose "run without debugger" ?
--- End quote ---
Yes, error still happens if "run without debugger" is chosen.

--- Quote ---Or are you running a Qt5 or Qt6 Lazarus ? I note you mention Qt6 creator ?
--- End quote ---
I'm running Lazarus 4.2 FPC 3.2.2 x86_64-linux-gtk2.
I installed Qt Creator mainly just to see if it would run. I had installed it previously on my old Lenovo laptop running Ubuntu 24.04 and liked Lazarus so much better I'd stopped using it. Currently installed on this computer is Qt Creator 17.0.2 Built on Sep 29 2025 00:08:56 based on Qt 6.9.2 (GCC 10.3.1 20210422 (Red Hat 10.3.1-1), x86_64)

--- Quote ---has nothing to do with GTK2 but is again a Wayland issue. Wayland's X-server concept is non-existing (by design) or very poor (as a bolt-on).
But you can change to Xwayland.
--- End quote ---
Yes, Wayland has caused some issues for sure. Initially I switched back from Wayland to X11 on my old laptop running ubuntu 22.04 but it seemed that they were going to push Wayland with Ununtu 24.04 so I'd been running Wayland on the old laptop since upgrading it to 24.04 and just been tolerating some things I didn't like. Lazarus always ran great on the old laptop, it was just really slow when runnning my CAD program, thus the switch to a "newer for me" computer.
I have tried switching to X11 on this unit and when on X11 this unit will lockup when I try to run or build within the Lazarus IDE requiring a manul power off/on to recover.
On a side note: I noticed that with my previous Lazarus built apps, any apps that were built with more than 1 Form will not run on this unit. The single Form apps work just fine.
Thanks for all your time. I've tried to answer the best I can. Much of this is way over my experance level.

· Is it at all possible to run GTK2 on this new an Ubuntu?!? I think they do 3/4
· Can GTK2 handle Wayland?!? -- I have my serious doubts
Try to get answers to these questions and then report back... :)
Personally I'm running PCLinuxOS, which is a rolling release distro, so FPC & Lazarus can indeed run with the latest. Mind you, I have Lazarus compiled for QT6...

Benny, Thank You :D. I've seen the Lazarus QT6 talked about but never looked into it. While looking through how to do this I saw talk of how QT disabled X11 calls or threads (or something along those lines, wish I would have copied that) so it seemed worth pursuing. I installed fpcupdeluxe-x86_64-linux-qt6 from the zip file and now Lazarus IDE runs great for me after compiling and running a small test project.
Thanks to all for replying to this post!

Diverod, I suggest you install tomboy-ng, its in the Ubuntu repo and will almost certainly allow multi windows. Install it, start it up, see multiple windows, close and remove it. It might leave a small config file that will not worry you.
Thats a Qt5 app, there is also a GTK2 version in the github repo, below.

1.Gtk2 can run if x11 libs are installed.
2.Gtk2 CANNOT handle wayland.
Let's clarify a bit:
gtk1,gtk2,qt4 - x11 only widgetsets under linux
gtk3, qt5, qt6: x11/wayland widgetsets under linux
Distant future: gtk4, qt7 - wayland only.
