Description Will Woods 2009-01-27 18:10:15 UTC

Using xorg-x11-server-Xorg-1.5.99.901-5.fc11 on x86_64, C-A-B no longer zaps X. I'm told this wasn't an intentional change, so there must be something strange going on.

This is mildly annoying when I boot my machine with the KVM switched away, and GDM comes up at 800x600. Normally I zap X and it happily restarts and gets the right resolution. 

I'll happily support disabling C-A-B by default if there's a better solution for this use case.

NOTABUG, upstream changed to DontZap enabled by default.

Comment 2 Warren Togami 2009-01-28 02:47:08 UTC

What is the xorg.conf syntax to enable it again, just for reference?

Comment 3 Matěj Cepl 2009-01-28 09:04:48 UTC

xorg.conf(5)

       Option "DontZap"  "boolean"
              This disallows the use of the Ctrl+Alt+Backspace sequence.  That
              sequence  is  normally  used to terminate the Xorg server.  When
              this option is enabled, that key sequence has no special meaning
              and is passed to clients.  Default: off.
