I have very similar problem with ATI Technologies Inc Radeon Mobility HD 3670.
By using latest upstream kernel (2.6.34-999-generic #201004211003) it is possible to use dual head, but the cable for the external monitor may be connected only after I log in. If the cable is connected before login prompt then both screens become black when login should appear (note that I use Kubuntu, didn't try on Ubuntu yet). -- Radeon HD 2600 - Dualscreen problem https://bugs.launchpad.net/bugs/556232 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
