Regarding Ubuntu 13.04: I just noticed that I am NOT restricted to a resolution of 1024x768 when using a kernel from an earlier daily build. Rather, mirroring works properly again in Ubuntu 13.04 with the Linux 3.8.0-7-generic kernel.
Mirroring may also work with kernels that are more recent than 3.8.0-7. But other than with 3.8.0-19 (with which mirroring doesn't work properly), I haven't yet had a chance to test more recent kernels. Of possible interest to some, rolling back to Linux 3.8.0-7-generic also cured a recent problem in which HDMI audio wasn't working with my Radeon card. See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/897008 So the problem seems to integral to the recent kernels updates. -- 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/xorg-server/+bug/1167301/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
