+Subject: glx/dri2: Paper over errors in DRI2Connect when indirect
+
+DRI2 will throw BadRequest for this when the client is not local, but
+DRI2 is an implementation detail and not something callers should have
+to know about.  Silently swallow errors in this case, and just propagate
+the failure through DRI2Connect's return code.
+
+Note: This is a candidate for the stable release branches.
