 I have a radeon 9600 card, with two devices connected:

I have the same card. One of my monitors doesn't send EDID and this config works
for me:

Section Monitor
Identifier  E481
Option  LeftOfH481
Option  IgnoreEDIDon
Option  DPMS
modeline1280x1...@lcd 108 1280 1326 1440 1688 1024 1025 1028

 Oh, yeah, that did the trick, thanks.

NP :)

 Where is this option documented, though? Not in my xorg.conf manual.
 
 $ man xorg.conf|grep -i edid
 $


For Debian it is man radeon

  Option IgnoreEDID boolean
  Do not use EDID data for mode validation, but DDC is still used
for monitor detection. This is different from NoDDC option.
  The default value is off.

Lots of good stuff in there...

 Right, have it in man radeon as well.

 The only side effect is that now KDE4's panel has a 1024 px width when
 the session loads, even though the desktop starts with 1280 px width -
 and I have to resize it each time.

 But I guess that's a question for KDE's mailing list...
 
 Well, it is somehow related to the X configuration...
 
 With the configuration below, X starts in 1024x768 instead of 1280x1024
 - why (then, KDE switches to 1280x1024, but the panel stays at 1024 px)?

Can you pastebin the full log and the full config.



 I even added:
 
 Option PanelSize 1280x1024
 
 but it doesn't make any difference - X starts in 1024x768.
 
 So - how can I start X in 1280x1024 when I use IgnoreEDIDon option?

Did you keep this line?
modeline1280x1...@lcd 108 1280 1326 1440 1688 1024 1025 1028 1066

AFAIK EDID tells the card about supported modes and timings. Without it you need
a manual modeline.

ATI X1950 - 3D across dual 1920x1200 screens using OSS driver

2008-11-06 Thread David Greaves
Hi

I want to drive 2 1920x1200 screens in a twinhead config using opensource 
drivers.

I am about to buy an ATI X1950 as I think it can achieve this using the new
radeon(hd) driver features.

Is the 3D buffer able to do this on this hardware?

I think the 2048x2048 limitation has gone up to 4096x4096 but I'd like to check 
:)

Agreed, it's about time X supported changing the DISPLAY out from under an
application. a follow-me type feature.
