The server is already patched to make that option true by default.

The user reports that he can install Pardus 2009 Alpha shipping with intel driver 2.7.1.

Sorry, he might be installed using fbdev. I am waiting a reply from him.

The user had reported the same issue when we use intel driver 2.4.3. We solved the issue with the patches here:

http://svn.pardus.org.tr/pardus/2008/devel/desktop/freedesktop/xorg/xorg-video/files/intel/

Probably this one solved:

Yes, he said that he used intel driver 2.7.1 and no problem occurs. It doesn't work after upgrading to 2.7.99.902.

would you please ask the bug reporter to attach the following:

1) a xorg.log with option "modedebug" "true" in xorg.conf
2) vbios dump. you can get vbios dump via:

# cd /sys/devices/pci0000\:00/0000\:00\:02.0/
# echo 1 > rom
# cat rom > /tmp/rom.bin
# echo 0 > rom

thanks.

From the Xorg log it seems that there is no EDID for LVDS. At the same time from the rom.bin it seems that there is no integrated LVDS controller.
   >LVDS config: No LVDS
Will you please ask the bug reporter double check whether the 2.7.1 driver can work well? If it can work, please attach the Xorg log on intel driver 2.7.1.
Please also attach the output of acpidump, dmidecode, lspci -vxxx.
Thanks.

try the debug patch in which the DVO timing is obtained by using the DVO timeoffset in LVDS data entry

Will you please try the debug patch and see whether the issue still exists?
Thanks.

Will you please double check it again?
I already check the vbios bin and find that the correct preferred mode can be parsed from VBT after applying the patch.

Thanks.

I already check the vbios bin and find that the correct preferred mode can be
parsed from VBT after applying the patch. 
But from the xorg log it seems that it still can't be parsed correctly.
Please double check it again.

Thanks.

Thanks for checking back, indeed I was wrong and somehow the drivers got installed into an incorrect location.  Once installed properly X started correctly.

Can/Should the patch be committed to git?

Thanks
