manually, though crash because used spa0.2
still need to install libnsl in fedora, however, installing libnsl on x64 works, but on arm64 crashed (though no librustdesk.so any more)
because it occurs since fedora 33, and since fedora 34, it was installed with the system by default
fix: set GDK_BACKEND to x11
