Hi Alex, You will need to use AMD's configuration tool for setting up the config you want, because it will require using Xinerama. The GNOME display properties tool only works for displays connected to a single video card; it can't do multi-card spanning.
If you need technical support for setting this up, the kind folks at askubuntu.com should be able to help guide you through using amdcccle to create your configuration. ** Changed in: xorg (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/914713 Title: virtual display memory too small, primary display resolution incorrect To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/914713/+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
