Question was:
:: X11R6, public-patch-13
:: CLIENT MACHINE and OPERATING SYSTEM: Sparc/SunOS 4.1.4
::
:: Sometimes when an user logs off, the keyboard stays un-programmed
:: or badly programmed. Only '/usr/X11R6/bin/kbd_mode -a' can
:: get out the strange state.
::
:: When the keyboard is out of use, the Num_lock LED stays green.
I finally found an explanation: everything is in the rate
of ioctl(). There's a patch from Sun :
Patch-ID# 102881-01
Keywords: /dev/kbd ioctl() repeating hang kbd ioctl 11c classic
Synopsis: SunOS 4.1.4: Repeating ioctl() to /dev/kbd goes to hang
Even with this patch, the problem still remains.
But slowing down the rate of ioctl() greatly reduces the number
of broken keyboards. To slow it down, I just trace(1) kbd_mode...
So now my /usr/X11R6/bin/xinit is:
#!/bin/sh
tmp=/tmp/tr.$$
/usr/X11R6/bin/xinit.bin "$@"
echo "Waiting 3 s..." > /dev/console
sleep 3
/bin/rm -rf $tmp
/usr/bin/trace /usr/local/X11R6/bin/kbd_mode -a > $tmp 2>&1
/bin/rm -rf $tmp
