Thanks Till. I tested a few more mainline kernels, including 3.8.3, 3.8.4, 3.8.5, 3.8.6, and 3.8.8. Unfortunately, mirroring also doesn't work properly with any of those tested mainline kernels. So at present, at least for me, the only relatively recent kernels that properly support mirroring in Ubuntu 13.04 on my AMD Radeon HD6670 are:
Ubuntu 3.8.0-7-generic Mainline 3.8.0 I hope to perform a clean install soon after Ubuntu 13.04 is officially released. If this bug hasn't been fix by then, I'd like to revert to one of the above kernels after the clean install. But unfortunately, if Ubuntu 3.8.0-7-generic isn't readily available for download at that time, I'll likely be forced to use mainline 3.8.0. So here's hoping that older (pre-release) Ubuntu kernels will be available after the official release of Ubuntu 13.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1167301 Title: REGRESSION: Mirroring display works only with 1024x768 (4:3) resolution whereas my laptop has 1366x768 (16:9) and the external monitor 1920x1080 (16:9) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1167301/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
