Created attachment 48994 [details] dmesg when starting X with HDMI2 unplugged Initially reported at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=633527 Since I upgraded my Dell Latitude E6410 laptop from Debian's 2.6.38-5 to 2.6.39-2 (tried 3.0.0-rc6 too), the machine hard freezes (even sysrq doesn't seem to work) when X starts with HDMI2 plugged. When KMS starts, both eDP and HDMI2 (DVI connector on the dock station) display the boot as usual. Later, when gdm starts, both screens blank and the machine freezes. If I unplug HDMI2/DVI before X starts, things work fine. I can even replug HDMI2/DVI later, the external display will be automatically enabled (and I can play with xrandr to change its resolution). 00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02) (prog-if 00 [VGA controller]) Subsystem: Dell Device [1028:040a]
