I upgraded to wolverine, and the first thing I had to do was "rpm -Uvh --force
--nodeps XFree86-4.0.1-1.i386.rpm" to get my 1280x1024 external display support
back again....

This is a high priority bug IMHO, and I am working on it with Dell, and
others.  I might have to pull in some code from the trunk, or get Dell
to send a patch or something.  I have an M3 here to test with, but I dunno
if it yeilds the same results as the laptop version.  I don't have the
funny cables to connect it up to anything other than a normal monitor.

Hopefully something can be worked out though.  I'm making this a must-fix

Does this work with XFree86-4.0.2-0.11.4, and the Xconfigurator available
at http://people.redhat.com/notting/Xconfigurator/

?

I tried with XFree86-4.0.2-12.1 + Xconfigurator-4.9.17-1 (the Xconfigurator you
mentioned above) and Xconfigurator-4.9.19-1.   No luck, exactly the same issue.
Is there something in particular that you hoped would work?

The ati driver, I could possibly try and debug if you needed.....  just remember
that this wasn't a problem with the RHL7 XFree86-4.0.1-1. :-)

Please try the combo of XFree86-4.0.2-12.1 + Mesa 3.4-11 + the latest
rawhide kernel.

If not, does it work with XFree86-3.3.6?

Xconfigurator --preferxf3

Please report back ASAP as time is very much of the essense here.

Update:  XFree86-4.0.2a-1, Mesa-3.4-12

Does this fix it?  If not what do "lspci -v" and "lspci -vn" show?

I'm on this now... You'll know very shortly.

Okay, XFree86-4.0.2a-2 and Mesa-3.4-12 applied.... "wolverineish" base (incl
kernel-2.4.2-0.1.20)

Still no luck....

See 1280x1024 modeline results above.  This does NOT happen with 4.0.1-1 (as I
mentioned before).  Everything looks fine except for the invalid logic - the ATI
driver only considers the res. of the laptop panel, not the res. of the attached
monitor (whether it be a flat panel or otherwise).

Hope this helps...  do you need me to try hacking on this??

AHA!!!  This is *NOT* a r128 Rage Mobility!!  (Personal eureka)

This means we have a common problem now between several people.  There is
another bug report or two against mach64 basedd mobility cards, and Preston is
also seeing this.  I don't have one to test here though.  Preston was looking
into this yesterday, so you might want to talk with him first.  Any help would
be greatly appreciated for sure!

*** Bug 31637 has been marked as a duplicate of this bug. ***

*** Bug 30651 has been marked as a duplicate of this bug. ***

Some more information on my progress....  "exceeds panel dimensions" message is
set in xfree86/common/xf86Mode.c, and corresponds to MODE_PANEL in
xfree86/common/xf86str.h .  The fn. ATIValidMode in
xc/programs/Xserver/hw/xfree86/drivers/ati/ativalid.c determines what modes are
valid and which aren't.

Now, I have inspected 4.0.1-1.3 (4.0.1a) and 4.0.2-6 since the first works and
second doesn't. Its not that 4.0.2 has added support for checking panel
dimensions (since this was in 4.0.1). What appears to be the case is that in
4.0.1(a) the ati driver correctly detected whether an external monitor was being
"used" or not - if so, it used external monitor details, if not, it used laptop
panel details.    4.0.2 with the same XF86Config-4 file _always_ assumes you're
using the laptop panel.

The bug appears to be in detection of, or setting a variable as to, whether the
external display is being "used" or not.

Okay....   http://www.xfree86.org/4.0.2/ati5.html#16   discusses the crt_screen
option.  It looks as though between 4.0.1 and 4.0.2 the handling of the
crt_screen option has _changed_.  (Its really useful to know this!!)

Current XF86Config-4 segment which WORKS for 1280x1024 external on a notebook
with 1024x768 panel:

Section "Monitor"
        Identifier "Dell 1701FP(Analog)"
        VendorName "Unknown"
        ModelName  "Unknown"
        HorizSync 31.0-80.0
        VertRefresh 56.0-76.0
        Option "dpms"

EndSection

Section "Device"
        Identifier "ATI Rage Mobility"
        Driver "ati"
        BoardName "Unknown"
        Option "crt_screen"     <-----
EndSection

Another option to maybe support in some way in the future!  The question is what
we should do next I suppose.

What I'm trying to work out is the logic in changing from something that seemed
to work fine before, to what we now have...

From http://www.xfree86.org/pipermail/newbie/2000-July/000076.html , Marc (the
author of the ATI code) says:

"""
Option "crt_screen" forces the driver to use CRT timings, essentially
ignoring the panel's existence.  If, despite this, you use the hot keys to
switch to the LCD, the panel will likely not sync to those timings,
especially for modes that don't match the panel's dimensions.  This
option will, however, allow modes larger than the panel (because it makes
the driver assume only the CRT will be used).
"""

hmmm....

Mike:

Please bring this to the ati driver author's attention.  For now, we have 
removed it from the critical list as there is a workaround, even though it is 
clumsy.

Ok, I'm sending the reports upstream to Marc Aurele La France, and
Kevin Martin.  Hopefully they might be able to help track this down and
possibly provide a fix, or some suggestions.

Marc says these problems are at least partially fixed in the XFree86 trunk
code, and not easily backportable to the current 4.0.x branch.  As such,
this issue is not likely to be fixed properly until XFree86 4.1.0 is released.

The "crt_screen"  option is thus the recommended way of dealing with this
for the time being.

Defering until XFree86 4.1.0 is released and in the rawhide tree, tested
and working...

dsainty: does this work in the 7.2 beta?

David, can you please comment on wether or not this works in the
latest release of XFree86 4.1.0.  I know for a fact that the 4.1.0
codebase has much enhanced flat panel support, etc.

I have an eng sample of this card, but it of course does not have
a flat panel attached, so I can't reproduce your test conditions.
Please respond.

TIA

I will need to borrow a screen and laptop in the office... I will attempt to do
this, this week.

There have been no further reports of problems on this by anyone,
so I am assuming this bug is fixed now in Red Hat Linux 7.2.  If
the problem persists, please reopen the bug report.

Thanks.
