I found this post on the ubuntu forums: http://ubuntuforums.org/showpost.php?p=10929081&postcount=8 and this wiki: https://wiki.ubuntu.com/X/Config/Resolution
So I did the following: used the modelines provided from the edid section of my Xorg.0.log to create a set of xrandr commands to append the start-up script: /etc/gdm/Init/Default however on restart the same old resolution started, but on going to Menu>Preferences>Monitor the new settings were there so I selected 1280x1024@60Hz and then clicked on the button "make default". On restart I had my desired screen resolution. (I have no idea how this action works or why appending the GDM start-up script didn't work.) Incidentally I got a random monitor detection whilst I was doing this for a Rogen Tech Distribution Inc 27" monitor...screenshot attached. I have this on a couple of occassions now. Also a new output for xrandr --verbose attached. ** Attachment added: "Screenshot" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/799379/+attachment/2196998/+files/rogentech.png -- 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/799379 Title: Monitor undected and screen resolution options missing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/799379/+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
