Hello,

I run on an Acer Aspire One D250 netbook the following system:

$ uname -a
FreeBSD La-Habana 10.0-CURRENT FreeBSD 10.0-CURRENT #0 r250588M: Sat Jun 22 14:15:48 CEST 2013     guru@La-Habana:/usr/obj/usr/home/guru/head/src/sys/GENERIC  i386

$ pkg_info | fgrep xorg

and on top of this KDE 3.5.10, but I think this is unrelated to the
problem:

sporadic the screen turns to white; the system is still running and I can:

a) SSH into it from LAN
b) switch with Ctrl-Alt-F1 to the alphanumeric console which is
   displayed fine and works
c) from alphanumeric with Alt-F9 back to the X11 screen, which is black
d) toggle between F1 - F9 (F9 stays black)
e) can zap the X11-server with Ctrl-Alt-Backspace, which returns to
   alphanumeric console, and can startx there again the X11-chain fine

Of course, zapping means loosing all open files in vim or pages in browser
and is not want I want.

One can think in a hardware fault, broken LCD cable or whatever, but why
then the alphanumeric console is fine and X11 starts fine again?

And, is there some way to re-init the screen in X11 again to not zap it
and loose the session?
