Bug 104597

Xorg.log (with configfile from 9.3)

Something for Matthias to investigate. 

FWIW, I am seeing the same strange behaviour on my IBM Thinkpad T42 (Radeon
Mobility 9600). SaX2 failed to create a functional xorg.conf for my external
Samsung SyncMaster 920T (see BUG#104640), so I wanted to revert to my previously
working org.conf from SUSE 9.3, which uses a Xinerama setup that spans both the
internal and the external display (see the xorg.conf attached). X start up, but
I only see a display on the internal panel. The external screen goes in
powersave mode and stays black. However, the Xinerama screen was set up
correctly, as the output of "xdpyinfo" confirms:

Working Xorg.conf from 9.3

This is the xorg.conf that used to work for Xinerama on 9.3 - in 10.0 I only
see the internal display.

Xorg.0.log for the 9.3 dualhead config file

As a workaround, I now copied the radeon_drv.o from SUSE 9.3 into
/usr/X11R6/lib/modules/drivers/ - now the dualhead setup works again.

*** Bug 104598 has been marked as a duplicate of this bug. ***

Let's track all Dual Monitor / Radeon problems in a single bug.
See there for a first workaround (clone mode only).

Please test again with beta2 (as soon as it is out), configuring as described in
bug #104640 (external monitor detached during X startup, re-confirm monitor). If
this works then, we at least don't have any regression.

What do you mean with both profiles? You shouldn't use profiles for radeon for
configuring dual head any more.

Please *always* attach *all* configuration and log files - in your case the 9.3
xorg.conf and the new xorg.conf, the Xorg.0.log for both configs with 10.0b1
Xorg and the Xorg.0.log for 9.3 Xorg.

This time please report to this bug, even though it is marked as duplicate.

Finally setting this bug to VERIFIED (FIXED) - on 10.3 beta2 everything works out of the box (except a small problem, see bug 306691). Even the framebuffer on tty1 is no longer broken :-)

Whatever you did: Thanks! - and please don't break the driver again, please ;-)
