[Bug 556232] Re: Radeon HD 2600 - Dualscreen problem

Thu Apr 22 10:32:08 UTC 2010

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).
