It's the VGA display that's unhappy. My "default" config for ARANDR, and therefore the one that the machine often shuts down and boots up as, is DVI + VGA enabled, HDMI disabled.
I notice, however, that on the screens that load prior to initializing X (the Ubuntu logo and the text output that's occasionally visible for half a a second as the machine is shutting down or resuming from sleep), the resolution seems to be 1280x720 (either stretched or not, depending), which is that of the HDMI projector. the VGA and DVI displays are both 1680x1050. If I hadn't been clear, I'm not experiencing failed boots -- just one of my monitors is unhappy until I disable and reenable it. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1140513 Title: X doesn't initialize displays properly on sandybridge when 3 screens connected Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: Bit of an odd one -- this started happening when I was using the oibaf repo, but I switched back to regular Quantual repos and it kept happening, so: Intel Sandybridge motherboards generally have 3 display outputs (VGA, DVI, and HDMI), but they can only drive two simultaneously. I have a display plugged into all three (two desk monitors in VGA and DVI, and a projector in HDMI), and Ubuntu's Displays application is generally very good about letting me switch between any combination of two (e.g. by disabling one of the two I have enabled, then enabling the third). The exception is at boot time, when (with some irregularity, but at least two times out of three) X seemingly tries to initialize all three displays, with one of them winding up running at something like 37Hz and either displaying a garbled image or nothing until I disable it and reenable it again, after which everything is fine. Thoughts?
