DPMS not working

[Rob Lahaye]

Guy,

I won't help much solve the problem.
All I want to say, is that I see the same thing on my system
(FreeBSD 4.8 with up-to-date-from-ports Xfree and other software).

I have a regular monitor, SamSung SyncMaster 20GLsi.
Indeed it only blanks. When I do "xset dpms force off" in my X-display,
nothing happens. I vaguely remember it used to work in the past (when my
OS was also Linux, instead of FreeBSD....).

However, when I go elsewhere, e.g. ctrl-Alt-F1 text screen, do a
"setenv DISPLAY <my-X-display>" and then repeat the xset command above,
"xset q" says "Monitor is Off".
Hmmm, but I'm on the same monitor, which is on !?!?

My wild guess is, that this may be broken with recent Xfree 4.3.0.

Or is only XFree broken in the FreeBSD ports collection? A wrong FreeBSD patch?

You may try to convince the FreeBSD or XFree lists/people to comment on this.

Regards,
Rob.
