Hi!I'm trying to get Sugar [1] to work inside TigerVNC on Fedora (it works fine inside RealVNC on Debian). The issue I'm having is that parsing key names doesn't work because XGetKeyboardMapping returns an empty (all-zero) keymap until a key gets pressed. It's easily reproducible using the test case given below. Because I know next to nothing about X11 programming, I'd like to make sure it's not us doing anything wrong (like forgetting to call some function) before I call it a TigerVNC bug.
Output on TigerVNC/Fedora (with a no-op .vnc/xstartup):[array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L]), array('I', [0L, 0L, 0L, 0L])]
(gdb attached to the real program showed that (256-8)*4=992 zero values are returned, above is limited to 20 values)
Output on RealVNC/Debian (with a no-op .vnc/xstartup):[array('L', [0L, 0L]), array('L', [65307L, 0L]), array('L', [49L, 33L]), array('L', [50L, 64L]), array('L', [51L, 35L]), array('L', [52L, 36L]), array('L', [53L, 37L]), array('L', [54L, 94L]), array('L', [55L, 38L]), array('L', [56L, 42L]), array('L', [57L, 40L]), array('L', [48L, 41L]), array('L', [45L, 95L]), array('L', [61L, 43L]), array('L', [65288L, 0L]), array('L', [65289L, 0L]), array('L', [113L, 81L]), array('L', [119L, 87L]), array('L', [101L, 69L]), array('L', [114L, 82L])]
Is there anything we might be missing? We're almost exclusively using gtk/gdk, but that doesn't mean there's nothing we could have done wrong.
