Hi, yesterday I had a coule of nasty experiences with xdm, the X display manager. Indeed I discovered the when pressing mod-q repeatedly XMonad will quit, instead of restarting, and you will be prompted with a new xdm login screen. I can always reproduce it: start X with xdm, and then login. Press mod-q twice or more and you are out. I cannot reproduce if I connect to Xmd from a remote X server launched with the -query option. For instance: /usr/bin/Xnest -ac -query localhost :1 will not reproduce the error. I cannot reproduce it with Kdm (I did not try with Gdm since it's not installed on my system). Can this be related to the way Xdm manages local sessions? I have the feeling that this could be the problem. By the way it is quite a nasty experience, not different from a crash. And the user should be at least warned. Ciao, Andrea PS: Instruction to run Xdm in a second X server: 1. change /etc/X11/xdm/Xserver to: :10 local /usr/bin/X :10 2. start xdm with: xdm The display you'll have to connect to will be :10. Now you can test the problem.
