I was using my laptop to play movies on my tv using hdmi. When I upgraded recently, which included a new kernel, the hdmi causes the computer to freeze, forcing a reboot. As long as I don't plug in the hdmi everything works properly. But the instant I plug in the cable the computer freezes. The wifi continues to function but nothing else. I can't switch to a terminal screen. The only thing I can do is reboot.
I have not tried going back to an earlier kernel but will try that soon. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1014473 Title: hdmi video out broken on package upgrade Status in “gnome-control-center” package in Ubuntu: New 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.
