More strangeness with X yesterday. When I booted up, X didn't recognize my keyboard (neither the external keyboard nor the built-in). I tried rebooting and restarting X (with Alt-PrtScn-K) several times to no avail. In the end I decided to reboot into command-line mode and update back to the latest Ubuntu version (i.e. ditch this fix and live with the original problem).
In addition to updating input-evdev, I noticed that it also updated xserver-common, xorg-core, and input-synaptics, plus a bunch of non-X11 packages. I guess these were Ubuntu's standard periodic patches. After updating and rebooting (docked with both monitors), X windows came back up successfully without freezing!!! However, it seems like this didn't fix the original problem, just worked around it. Whenever I try to move the monitors around in Display Settings, then X freezes again. I think they found a combination of randr settings that don't trigger the defect and then made those the default when booting with dual monitors. .config/monitors.xml attached, if anyone cares to check it out. ** Attachment added: "monitors.xml" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/992778/+attachment/3226152/+files/monitors.xml -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/992778 Title: Dual Monitor Freeze after changing Display Settings in ubuntu 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/992778/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
