Description s 2011-08-27 11:02:49 UTC

When I try the following:

#!/bin/bash
xkbcomp - $DISPLAY<<EOF
xkb_keymap {
xkb_keycodes  { include "evdev+aliases(qwertz)"};
xkb_types     { include "default"};
xkb_compat    { include "default"};
xkb_symbols   { include "pc+de(nodeadkeys)+inet(evdev)+capslock(escape)"    };
xkb_geometry  { include "pc(pc104)"};
};
EOF

my X server crashes and restarts. This behavior is reproducable, though I did not yet try it with another system.

Comment 1 Daniel Stone 2012-10-31 01:20:03 UTC

The log just shows your server closing down normally, with no sign of a crash anywhere.  Do you have any other clients running when you do xkbcomp? The default behaviour of the X server when the last client exits is to reset; this is actually part of the spec (unfortunately).  If this is undesirable, you can start the server with -noreset.

Comment 2 s 2012-10-31 07:51:58 UTC

I am sorry, I do not have the system exhibiting this bug anymore. If I remember correctly, at the time the only other clients running were the awesome window manager (that should not quit without being asked to) and an rxvt-unicode (which I did not close either). According to your explanation, it could also be a bug in awesome. I just tried to reproduce the bug (still using awesome, though with some more clients), and now xkbcomp just segfaults:

xkbcomp - $DISPLAY<<EOF
xkb_keymap {
xkb_keycodes  { include "evdev+aliases(qwertz)"};
xkb_symbols   { include "pc+de(nodeadkeys)+inet(evdev)+capslock(escape)"    };
xkb_geometry  { include "pc(pc104)"};
};
EOF

produces:

zsh: segmentation fault  xkbcomp - $DISPLAY <<<''

I use xkbcomp v1.2.4, a not-very-helpful stacktrace follows:
