It was easy enough for me to use "svn diff -c r319722" & "svn patch --reverse-diff" to effectively revert r319722. I re-ran the build after that, and a subsequent reboot allowed me to "sudo service hald onestart" (which whined a bit about dbus not being enabled but started it anyway), after which I was able to start xdm -- so that seems to have been successful. Perhaps I'll chat with Gleb a bit later today. :-) (Our cubes are adjacent.) Thanks, Konstantin! :-) Peace, david -- David H.
