    This is listed on https://doc.qt.io/qt-5.15/linux-requirements.html as "recommended", and doesn't seem to be needed (only used for windowing over multiple screens support?) , and the fact that it's no-longer installed by default on modern linux distros (i.e Ubuntu), is annoying/confusing for users. See:

    #30061 #32097 #33197 https://bitcoin.stackexchange.com/questions/122646/libxcb-xinerama0-library-required-by-bitcoin-qt

    I haven't tested the GUI with these changes. Just opening an alternative to #33197. Note that we also already have libxcb-cursor0 documented as a potentially missing runtime dependency (see build-unix.md).

    (only used for windowing over multiple screens support?)

    Deprecated by and incompatible with XRandR which was introduced in ~2001.

    ACK decc3671c88bb3acdf137c6bc46892f99319104e.

    This PR doesn’t affect the bitcoin-qt executable, since libxcb-xinerama.so isn’t used even in the current master branch @ 7d9789401be4c91a9eb3c1112564a6524bdc4f70.
