I have another machine with an Intel video card: 00:02.0 VGA compatible controller: Intel Corporation 82G965 Integrated Graphics Controller (rev 02) that shows the same blank-screen symptom on boot. It is running kernel 2.6.33: Linux maestro 2.6.33-gentoo #2 SMP PREEMPT Sat Mar 20 17:55:48 EDT 2010 i686 Intel(R) Core(TM)2 CPU 6600 @ 2.40GHz GenuineIntel GNU/Linux If I log in blind on this machine (which has only one screen), X works fine. This is beyond my knowledge of the driver. Please file a bug upstream [1] and paste the URL here so I can track the bug too. Thanks [1] http://intellinuxgraphics.org/how_to_report_bug.html I found the answer in a thread on the arch linux forum. It turns out that you have to remove any 'video=' parameters from the kernel boot line, and then everything works fine. And my X problem turned out to be that the names of the devices had changed, and so my script that sets up my dual screen wasn't doing anything any more because it was using the wrong names. |
