Subject: [PATCH] xcb: Ignore disabling of outputs in the middle of the mode
|
|
switch
|

MIME-Version: 1.0

X server may send RROutputChangeNotify event with null crtc and mode,
|
|
when it switches an output mode. Request RROutputInfo to distinguish
|
|
this case from the case when the output is explicitly disabled.
