My guess is that there are two bugs here. The obvious difference between the failed & correct logs is that the correct logs have a 1920x1200 mode (and, in fact, just more modes), and the failed logs don't. It'd be good to grab the EDID in both cases, but also to test the kernels at http://people.canonical.com/~smb/i915-edid-test/ .
The second problem - where everything thinks it has brought up the 2nd monitor, but it doesn't work, and then clone mode doesn't work - may well be related. What behaviour does the monitor show? Is it displaying a “sync out of range” message or something similar? -- T61 does not start in clone mode with external display attached https://bugs.launchpad.net/bugs/610413 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
