:Hi dudes,
:I think I meanwhile tested X quite exhaustivly on DragonFly. To put 
:aside any doubts, I consider myself as an average user. I built both 
:X.org 6.7 (XFree 4.4) and XFree 4.3 from ports and installed both as 
:well as packages afterwards. Never tried to build from the original 
:sources though.
:I always got a graphical environment after a bit of fiddling, but also 
:experienced some very strange behaviour everytime. E.g. X always froze 
:my box a when I killed it with ^AltBackspace. The machine also died 
:when I tried to fall back to a VT via AltFx. Same when I exited the 
:Died means it wasn't accessible via the keyboard anymore nor via ssh.
:The screen went just black and the only way to recover was a cold reboot.
:I could derive some things that let X (and also my machine) die at 
:- loading of vesa.ko
:- using any cursor-icon except CORE
:- Monitor Option "DPMS" set in configfile (OK, my monitor)
:I've installed XFree 4.3 and X11R6.7 (XFree 4.4) on Linux and OpenBSD 
:and never had any problems like those.
:I'd be grateful if anybody could confirm this, since I'm not really 
:sure that I'm the only one.
:Thanks in advance

    Sounds like the video switching is broken.  This is the first bug 
    report I've heard in a while related to video switching so it is 
    likely an X video driver issue.  It might be possible to get more
    information out of the box if you have a second machine you can attach
    a serial console to, and then see if you can break into DDB via the
    serial console after it freezes.  Alternatively it might be possible 
    that the 'freeze' is in fact a panic.  If it is a panic and you have a
    dump device set up the system might be able to dump the kernel core to
    the swap partition... you would see the HD lamp light up for up to
    a few minutes (depending on how much memory the box has that needs to
    be dumped) when the box freezes.
