commit 28c0579ff4f74a256f3fe8e6462b6c507848cec6
Author: Chris Feng <address@hidden>
Commit: Chris Feng <address@hidden>
Avoid using the global value `x-display-name'
* xcb.el (xcb:connect-to-display-with-auth-info, xcb:connect-to-socket):
Use the frame parameter 'display' instead of `x-display-name' since the
latter can be cleared by e.g. launching an emacsclient.
