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: http://svn.pardus.org.tr/pardus/2008/devel/desktop/freedesktop/xorg/xorg-video/files/intel/ubuntu/26_i830-use-lfp-data-ptrs.patch

I am waiting a reply from him. 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.

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.

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
