Super fun. You could try setting (one or both of) these before running leo, and seeing if that makes any difference.
QT_QPA_PLATFORM_PLUGIN_PATH= /usr/lib/qt6/plugins/platforms/ QT_PLUGIN_PATH= /usr/lib/qt6/plugins/platforms Another possibility is a bad copy of libqxcb.so in your /home/<username>/.local/lib/python3.<version>/site-packages directory somewhere. I've never installed leo via pip, but if it pulled in a copy of that lib somewhere in there that's not playing well with the system libs, that'd be a possibility. IIRC the 'cv2' python lib ships that library with it, maybe see if that's in there somehow? Or just do a recursive find for it -- `find /home/<username>/.local/lib/python3.<version>/site-packages -name libqxcb.so -ls` (or similar). Sorry this is being one of those mystery pains. :( Jake On Mon, Jul 22, 2024 at 11:32 AM [email protected] <[email protected]> wrote: > Yes, /usr/lib/qt6/plugins/platforms/libqxcb.so exists.
