I've experienced recently, that my keyboard doesn't work as intended: the layout is incorrect and the compose key is not functional. I've found two relevant log entries possibly related to the problem: Xorg.log: (**) Option "xkb_rules" "evdev" (**) Option "xkb_model" "evdev" (**) Option "xkb_layout" "hu,us" (**) Option "xkb_variant" "standard" (**) Option "xkb_options" "grp:shift_toggle,compose:ralt" (EE) XKB: Could not invoke xkbcomp (EE) XKB: Couldn't compile keymap (WW) Couldn't load XKB keymap, falling back to pre-XKB keymap grsec.log: grsec: (root:U:/usr/bin/Xorg) failed fork with errno -12 by /usr/bin/Xorg[X:pid] uid/euid:0/0 gid/egid:0/0, parent /usr/sbin/gdm-binary[gdm:pid] uid/euid:0/0 gid/egid:0/0 xorg-server-1.5.3-r6, xkbcomp-1.0.5, setxkbmap-1.0.4 I know, that I'm using a hardened experimental system, but the new evdev based keyboard interface was previously working well for the past few weeks before this issue popped up. Any ideas would be greatly appreciated.

The issue might be related to PaX/Grsec. It popped only on the Athlon MP server, while no sigs of fork failures on my Pentium M laptop. The toolchain is the same. I'll get back upon any news on this one. BTW hardened-sources-2.6.28-r8 failed to load on that Athlon MP, while the laptop was doing well. When I was about to take a screen capture of the remote console, hardened-sources-2.6.29 came out and the kernel loaded well. There were no problems except for the fork failure.
I have no idea what this all means. I'm not sure there's anything we can do here. I'll gladly admit that X has a natural tendency of breaking in random and unpredictable ways but xkbcomp's usage in X hasn't changed for years... Do let us know how things evolve. Thanks

It turned out, that disabling PAT support workarounds the issue. Regards, Dw.
