Unable to use flyover-mode in Fedora 42 and Emacs 30.1

[colding]

Hi,

I've tried using flyover, but to no avail. At the end is a very simplistic init.el that I ended up with, to see if something else in my setup was the culprit, but to no avail. When invoking M-x flyover-mode, I get a message saying "Flyover mode disabled in current buffer". I cannot seem to enable it. However, I once got flyover to display one of its nice popups, but I could never replicate it, not even without changing a thing in my setup. I also have experienced frequent freezes, where emacs locks up my entire laptop so I have to reboot. There's nothing of interest in Messages, except repeated instances of:

LSP :: clangd:4483 initialized successfully in folders: (/home/colding/work/ResolvePoint)
Before sorting: nil
After sorting: nil
Error levels: nil
Before sorting: nil

I will be very willing to try out potential fixes.

Cheers,
jules

INFO:

I'm on Fedora 42 with all updates applied.
Emacs is 30.1.

Here's a screenshot of how my emacs looks while in a cpp file with the simple init-el below.

;; A very simple init.el
(require 'package)
(add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t)
(package-initialize)
(use-package lsp-mode :ensure t :hook (c++-mode . lsp-deferred))
(use-package flycheck :ensure t :hook (c++-mode . flycheck-mode))
(use-package flyover
:ensure t
:config
(setq lsp-diagnostics-provider :flycheck)
(setq flyover-checkers '(flycheck))
(setq flyover-debug t)
)
(add-hook 'flycheck-mode-hook #'flyover-mode)

I do suspect that the freezes are more of a Fedora 42 issue, than a problem with flyover. But flyover should still work, at least while my machine is unfrozen ;-)

Did you give up on flyover or did you find a solution or what's causing it to freeze and not work?

[colding]

I suspect it's multiple issues, not necessarily Flyover. For one thing, my laptop only has 4GB RAM, so it freezes from time to time. I've ordered a newer one, so I'll test flyover again once I get it and report back here. Hopefully some time this month :-)

And the testing will then be done on F43.

I don't think the ram is the issue, hope you can solve it.

OK, it took some time to get that new laptop, but now it's here and flyover works perfectly :-)

I hope that I did not spread too much misplaced alarm, since my old laptop was obviously the issue, even though I can't say how or why...

Anyways, it works, works well and I'm happy.

Cheers and thank you for your patience :-)
