>Description:
out of idle curiosity i tried dga(1) from the bash command line and
found it a somewhat simple colour-showcase. whenever i hit `q' to get
out of it, the Xorg(1) server crashes.
the output from the log is:
...
AUDIT: Sun Jun 3 16:32:41 2007: 11294 X: client 5 disconnected
AUDIT: Sun Jun 3 16:33:14 2007: 11294 X: client 6 disconnected
AUDIT: Sun Jun 3 16:34:11 2007: 11294 X: client 5 connected from local host (uid 0)
Auth name: MIT-MAGIC-COOKIE-1 ID: 67
Fatal server error:
Caught signal 11. Server aborting
the lines on the console end with:
xinit: connection to X server lost.

urxvt: X connection to ':0.0' broken, unable to recover, exiting.

i could re-attach to the screen session, and i have what little is in
the gdb(1) backtrace from the Xorg corefile. the ptty had:
