We started out with the realization that ctrl-alt-backspace would not work on our FC4 lab machines to restart the X server. Research led us to inset the following clause in the xorg.conf to disable this key sequence altogether: Section "ServerFlags" Option "DontZap" "true" EndSection Logic then led us to wonder if the clause: Section "ServerFlags" Option "DontZap" "false" EndSection would allow ctrl-alt-backspace to operate as it should. The answer we found was sometimes. In several cases two machines with identical hardware and identical software would have different behavior. One of the pair would work and the other would go into a crazy state where rebooting became necessary. Does anyone have any further wisdom of this matter that they are willing to share? -- ======================================================================= Do not meddle in the affairs of troff, for it is subtle and quick to anger. ------------------------------------------- Aaron Konstam Computer Science Trinity University telephone: (210)-999-7484
