I guess it's another bug:

$ ck-list-sessions
Session1:
 unix-user = '1001'
 realname = 'gg'
 seat = 'Seat1'
 session-type = ''
 active = TRUE
 x11-display = ':0'
 x11-display-device = '/dev/tty7'
 display-device = ''
 remote-host-name = ''
 is-local = TRUE
 on-since = '2010-05-24T18:10:36.520276Z'
 login-session-id = ''
 idle-since-hint = '2010-05-24T19:20:52.676562Z'
Session5:
 unix-user = '1001'
 realname = 'gg'
 seat = 'Seat2'
 session-type = ''
 active = FALSE
 x11-display = ''
 x11-display-device = ''
 display-device = '/dev/ssh'
 remote-host-name = 'gg-laptop'
 is-local = FALSE
 on-since = '2010-05-24T19:21:59.087478Z'
 login-session-id = ''
$ export DISPLAY=:0
$ xgamma -gamma 1.0
And the terminal hung after the last cmd Ctrl-C gets it back. Keyboard,
mouse are still dead on target/problem machine, screen black. I just
NX'ed in the problem machine & that is working fine. Anything else you'd
like me to check while it's in this state?
