What kernel are you using?  Does a newer kernel help?  Try 3.0 or 3.1.

As a workaround in the meanwhile, I deactivated the KDE screen power-mgmt and
just use an initial "xset dpms 240 0 0", which just triggers a "stand-by" after
240sec and no "suspend". This works without problems (stand-by and wakeup
from).

Anyway, I will also retry a bit and do some testing using "suspend" on a 3.1,
to see if something changed.

DPMS standby, suspend, and off states are all treated the same from the
driver's perspective.  The driver really only deals with 2 DPMS states on and
off.

When you say suspend, are you talking about the DPMS display state, or suspend
and resume of the entire laptop?  The two are very different.

Ok, interesting to know. Now somehow the way using "xset dpms 240 0 0"
(stand-by) quite surely made a difference for me at the time (<3.1) - but I
can't prove and explain in detail.

Now currently I'm using "xset dpms 0 240 0" (suspend) with 3.1 and until now it
wakes up quite reliable. Which would be in inline with your info, that the
driver operates on the same two states, as with stand-by. 

Maybe I'll also retest again the KDE power mgmt setting way, where I originally
observed the wake-up problem. Maybe it's some screwed side effect in the end.

No, no - I'm really talking about pure display suspend/resume, on a desktop
with an Asus screen. Only the display is suspended and should nicely wakeup
again, when I tick the mouse ;).

Sorry about the disappearence for a long time. I thought I had enabled the notifications for this bug.

It seems that I still have this very same problem even with kernel.org 3.2.5 kernel. The previously mentioned workaround "xset dpms 0 240 0" that helped
someone, did not work in my setup at all.

In case the following debug info helps at all:

Hi,

Just for info: in my case, since quite some time using 3.1 and 3.2 (and on debian xorg 7.6+11, radeon 6.14.3-2) the screen wake-up works quite reliable now,
without the xset dpms workaround.

I kept postponing to give an update on this on - sorry. Anyway, it looks better here in the meanwhile ;).

BR, Oliver

I tested with the latest git version from yesterday evening (13d261932bbfff7f45f288c5c8cce43177cccd3b) and unfortunately none of the "xset dpms force off,
standby or suspend" worked any differently than before.
The BenQ monitor just decides to stay in power saving mode and the only way to wake it up is to power cycle the monitor.

There really is nothing wrong with the hardware as the fglrx is able to use dpms power management just fine.

I just updated to latest Ubuntu 12.04 pre-release and the combination ATI 5450
together with BenQ LCD monitor doesn't work any better than before.
The system is still running with the kernel.org 3.3-rc3+ kernel from git.

I wonder what kind of information would help in figuring out why this
particular combination doesn't wake up from standby ?

I just happened to test with this very same 3.3.0-rc3 kernel that while I was
in linux console ie. no X and the screen blanker got activated, the lcd display
was put into suspend mode ---> I hit the keyboard at this stage and the screen
came back without fuss. Last time when I tried all the different stages with
xset, none of them worked well. Is there an easy way to modify the states the
console screen saver is using (for testing purposes) ?

You can use xset to test dpms, e.g.,
xset dpms force off

Also, for what it's worth, the driver only implements two states: on and off. 
All of the intermediate dpms states that are not "on" map to "off".

What I meant was the problem existed also in linux console, outside of X11.
However, it seems that at least the LCD display seems to work just fine with an
old ATI HD 2400 card & radeon driver (dpms works just fine):

08:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV610
video device [Radeon HD 2400 PRO]

I'll try the latest git version of kernel.org kernel as there has been some
updates to DVI connectors/connections code for radeon to my knowledge.

I'm seeing the same kind of issue here on my 3 monitor setup with Dell u2412m
monitors.

The 2 DVI connected monitors wake every time, but the Display Port one rarely
wakes if the screen has been off for awhile.

I have so far been loading display properties and making a change to that
monitor (like rotating it) and hitting apply, which wakes it, and then just
reverting the changes. Powering off and back on again didn't seem to help if I
recall correctly. I'll have to try again the next time I run into the issue.

Just had it not come back on again, so I tested the power off/on trick to get
