>Environment:
System: NetBSD argo.mewburn.net 1.6_BETA3 NetBSD 1.6_BETA3 (ARGO from GENERIC-$Revision: 1.491 $) #1: Fri Jun 28 08:52:16 EST 2002 lukem@argo.mewburn.net:/var/scratch/obj.i386/usr/src/sys/arch/i386/compile/ARGO i386
Architecture: i386
Machine: i386
>Description:
screenblank(1) checks if the atime or mtime of "input" devices
has changed to determine if it should "unblank" the display.
the default input devices are /dev/wskbd and /dev/wsmouse (the
wsmux devices). these don't update their atime or mtime when
events (such as an arbitrary keypress) occur.
>How-To-Repeat:
start up screenblank(1) on a wscons framebuffer.
notice that pressing a CTRL key or moving the mouse doesn't
unblank the screen. add "-i /dev/ttyE0" to rc.conf(5)'s
screenblank_flags so that at least screen output results in
the unblanking if you press a key that results in a character
output.
>Fix:
no idea. i tried to work out how (pseudo) devices update
their [acm]time values and got lost in the kernel :(
