Due to Xinerama's design, monitor hotplugging can't work there. However, it does work with XRANDR and KMS.
fglrx now supports XRANDR 1.2 (but not KMS). I can't easily test this on my own hardware but suspect it should work properly now. Would you mind testing oneiric (using fglrx with RANDR and not Xinerama) and report if it is indeed working? If it isn't working, please update the bug report with newer info by running the command: apport-collect 688403 ** Package changed: xorg-server (Ubuntu) => fglrx-installer (Ubuntu) ** Changed in: fglrx-installer (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/688403 Title: Xinerama secondary screen still exists when unplugging cable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/688403/+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
