I have some new information. I did a clean install of F37 on a virtual
machine. Although I usually use KDE, I used the vanilla Fedora iso
install which uses Gnome, so as to avoid any non-standard surprises. At
first, I didn't even update the system before doing the following.
I installed lyx-devel-beta2 from the jamatos repo using dnf. The
install went cleanly including basic dependencies.
Loading my test files into LyX I found preview inoperative, but fixed
this by installing the tex-preview package and reconfiguring (possible
dependency for tex-preview?).
Preview now (mal)functions exactly as before: preview normal with no
float inset, preview fails with float inset.
But I now get some new, possibly more informative error messages. When
clicking in and out of an equation to force preview I get the following
messages at the terminal:
Warning: Failed: dvips lyxpreviewkqkzoE.dvi ... looking for PDF
Error: Failed to extract metrics info from lyxpreviewkqkzoE.log
Version information for this install:
Version 2.4.0-beta2 (Sunday, December 11, 2022)
Qt Version (run-time): 5.15.6 on platform xcb
Qt Version (compile-time): 5.15.8
OS Version (run-time): Fedora Linux 37 (Workstation Edition)
Python detected: python3 -tt
python --version gives: Python 3.11.0
After doing the above, I fully updated the system. LyX behavior is
unchanged (still shows problem). Same error messages.
Version information after update:
Version 2.4.0-beta2 (Sunday, December 11, 2022)
Qt Version (run-time): 5.15.8 on platform wayland
Qt Version (compile-time): 5.15.8
OS Version (run-time): Fedora Linux 37 (Workstation Edition)
python --version gives: Python 3.11.1
I have tried these tests both as a normal user and as root. Same results.
Hope this helps.
