Hi, I have a W520, too, and have exactly the same problems since an LTS->LTS upgrade to 14.04. I now at least have a semi-workaround when starting the display manager with two screens:
Using nvidia-settings, I was able to generate a xorg.conf file that starts with a working two-screen configuration, without panning. File is attached. I guess you'd either need to adjust the values specific to my setup, or try to use nvidia-settings to generate a fresh configuration file. Important hint is to click on 'Advanced...' at the bottom to get the panning configuration. However, when switching between single- and dual-screen modes, screen panning will reappear and I have not figured out how to solve that yet. Switching to single-screen mode works once, using xrandr --output LVDS-0 --mode 1600x900 --pos 0x0 --output DP-0 --off --output VGA-0 --off Hope this helps. ** Attachment added: "xorg.conf file working on W520 for dual screen without panning" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1326688/+attachment/4269592/+files/xorg.conf -- 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/1326688 Title: Can't disable panning on multiple monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1326688/+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
