** If you encounter X protocol errors
-Try evaluating (x-synchronize t). That puts Emacs into synchronous
-mode, where each Xlib call checks for errors before it returns. This
-mode is much slower, but when you get an error, you will see exactly
-which call really caused the error.
+The X server normally reports protocol errors asynchronously,

+To get clear information about the cause of an error, try evaluating
