This is the contents of dpkg.log from 2012-6-14 through 16. On the 14th there was a Linux kernel upgrade. That's the only thing I can recognize as potentially being problematic.
I tried to set the bug to gnome-display-settings, but that package appears to no longer exist. I'm not sure how to refer to the display settings tool from within system settings, and doubt it's a problem with that tool anyway; on startup the hdmi interface monitor is blank, and in the past it mirrored the vga monitor's startup splash screen. ** Attachment added: "dpkg.log from 2012-6-14 through 16" https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1014473/+attachment/3194424/+files/dpkg.log.2012-6-16 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1014473 Title: hdmi video out broken on package upgrade Status in “lightdm” package in Ubuntu: Incomplete Bug description: I have two external monitors, one running through the vga out port and the other the hdmi out port and both were working fine in a dual head configuration until a recent package upgrade. Now only the vga out works and in the dispaly manager the hdmi connected monitor does not appear. I have another open bug about triple head not working here: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- ati/+bug/931240 (laptop monitor won't work in tandem with two external monitors) but this is the first time for my hdmi out to go dead. I've tried creating a new account to see if it was user specific settings creating the problem, but a new user account exhibits the same behavior. I would like to know which package upgrade I need to reverse in order to get my workstation back to full functionality.
