<pre>Thanks, now I understand what's happening:
It's a bug in the tigervnc vncHooksBlockHandler function, it doesn't handle the
function wrapping correctly: It keeps calling RADEONBlockHandler_oneshot,
although that function sets pScreen->BlockHandler = RADEONBlockHandler_KMS.
vncHooksBlockHandler needs to re-retrieve the current pScreen->BlockHandler
pointer after calling it.
Though if it turns out difficult to get this fixed in tigervnc, we can consider
a workaround.
P.S. This would also happen with the modesetting driver as of xserver 1.19.</pre>
