This error can't be real, in the sense that it's almost certainly not something the server actually sent. 'resourceid' in hex there is 0xC2042444, which isn't a legal value for the client application to ever see (three most significant bits ought to be zero, and aren't). But more importantly... > #11 0xf73..... in _XIOError () from /lib/libX11.so.6 > #12 0xf73..... in _XEventsQueued () from /lib/libX11.so.6 > #13 0xf73..... in XEventsQueued () from /lib/libX11.so.6 > #14 0xf74..... in _XtWaitForSomething () from /lib/libXt.so.6 > #15 0xf74..... in XtAppProcessEvent () from /lib/libXt.so.6 An I/O error indicates that the connection has _closed_, not that a protocol error happened. What are you doing to provoke the server into closing your connection? - ajax _______________________________________________ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
