It seems like if I force audio off at the same time I add the external screen, through xrandr, it does work reliably(?) so far. Using the monitor control panel or fn-f7 apparently puts audio back to the 'auto' setting, which does induce a problem
I tried running for i in `seq 30` ;do; echo i && xrandr --output DP1 --off && sleep 15 && xrandr --output DP1 --mode 2560x1600 --above LVDS1 --set audio off && sleep 15 || break;done and this got through 14 iterations successfully. Now I wonder if I can identify what the problem is with audio or provide a way to force it off. This screen does have an option for speakers to be connected, but I'm not using it. I don't know if it picks up audio across dp. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/745112 Title: [arrandale] desktop is messed up with external monitors (x86_64) To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/745112/+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
