Regarding Ubuntu 13.04: I have a similar problem with an AMD Radeon HD 6670 card connected to two monitors. One monitor (connected via DVI) has resolution 1440x900 (16:10) and the other monitor (connected via HDMI) has resolution 1360x768 (16:9).

In my case, when using the "mirror displays" option with the above described hardware setup, the highest resolution available is 1024x768 (4:3).

I'll just add that:

- In an earlier daily release of Ubuntu 13.04 (back in late December of 2012, if I recall correctly), the highest resolution available was 1360x768 (16:9) when using the "mirror displays" option on the same hardware setup as described above. So something related to this problem in 13.04 seems to have changed in late December of 2012.

- Up until very recently, Ubuntu 12.10 also offered a resolution of 1360x768 (16:9) when using the "mirror displays" option on the same hardware setup as described above. But in a very recent update of (sometime in April of 2013), 12.10 also now only offers a resolution of 1024x768 (4:3) when using the "mirror displays" option on the same hardware setup. So something related to this problem in 12.10 seems to have changed in early April of 2013.
