Starting with gentoo-sources-2.6.39, and also with 3.0.0, my laptop appears to freeze when X starts if I have an external monitor connected. Unfortunately, because it appears to be a kernel panic, and because X blanks the screen, I am unable to see the panic message itself, and also nothing appears in the log, which makes this a very difficult problem to search for to determine if it has already been reported. If I disable the xdm init script, the machine boots to the console just fine. Also, if I do not have any external monitor connected, X will start and operate just fine. If I add the external monitor after I am already logged in to KDE, the second monitor will operate correctly. I have been able to reproduce this problem with two different external monitors to verify that it isn't the particular monitor I am connecting. gentoo-sources-2.6.38 does not suffer from this problem. Reproducible: Always Steps to Reproduce: 1. Connect an external monitor 2. Boot the machine, with xdm enabled, or start XDM. Actual Results: The laptop's screen appears to turn off (backlight off). The external monitor is on, with a non-blinking cursor appearing in the upper left corner of the screen. At this point, the machine appears to be completely frozen, not responding to ping requests. I am also not able to get to any of the virtual terminals. Expected Results: The machine should boot into KDM. I am currently using x11-drivers/xf86-video-intel-2.15.0-r1 (the failure also happens with 2.14), and sys-kernel/gentoo-sources-3.0.0 (also happens with 2.6.39). $ emerge --info Portage 2.1.10.3

I should mention that I have no xorg.conf at all.

This is a Dell E6510.
have you checked the Xorg.0.log, Xorg.0.old, .. etc in /var/log for clues?
(In reply to comment #4) > have you checked the Xorg.0.log, Xorg.0.old, .. etc in /var/log for clues? I have, and there is nothing of interest written there. There is also nothing of interest in /var/log/messages. I believe this actually makes sense, since it appears to be a kernel panic. The kernel doesn't have a chance to flush any logging messages that might have been generated to disk, and likely only displays the panic trace on the virtual terminal, which I am unable to see since I am in the middle of a borked X session. I appreciate that this gives very little information to go on to help resolve this problem. It's sort of a "help, my computer broke!" kind of report, which is difficult and frustrating. If you know something I can do to see that traceback, I'd love to try it. Is there a way to ensure that kernel panics get logged and fsync'd before the kernel freezes?
I confirmed that this also happens with gentoo-sources-3.0.1.
Looks like you've already given all the info we might ask from you. The best course of action now is for you to file a bug upstream [1] where Intel developers will (hopefully) be able to sort this out. Please don't forget to add "remi@gentoo.org" as a CC on the upstream bug. I'll gladly assist you if you need any help to try patches should upstream request you to try one. Thanks [1] http://intellinuxgraphics.org/how_to_report_bug.html
Whoops, I clicked too fast. Sorry for cutting you guys out of the loop.
Hey Rémi! I created the upstream ticket at https://bugs.freedesktop.org/show_bug.cgi?id=40257
Yesterday I upgraded to gentoo-sources-3.0.3 and also to xorg-server-1.10.4 and it works again. I'm not sure which of these packages solved the problem, but I'm satisfied knowing that the latest available packages solve my problem, so I'll resolve this ticket.
