Dual monitors, bad resolutions in GDM

[dje]

Binary package hint: gdm

I have a laptop screen with a resolution of 1366x768 and an external monitor connected via VGA, the external monitor has a resolution of 1280x1024. Graphics card is ATI Mobility Radeon HD 4570 using the default open source driver.

When Plymouth loads, I get a cloned splash screen on both monitors at their correct resolutions. This is really nice.

Once GDM starts the monitors remain cloned but the resolution of both screens drops very low. This is not very nice.

While logging in the correct resolutions are set again and screens move into extended mode. This is really nice.

Expected behaviour: Resolution should be consistent throughout the startup process.

I have also tried 10.10, the issue remains

Thanks for the report, it has been some time without any response or feedback in this bug report and we are wondering if this is still an issue for you with the latest release of Ubuntu the Natty Narwhal, May you please test with that version and comment back if you're still having or not the issue? Please have a look at http://www.ubuntu.com/download to know how to install that version.Thanks in advance and sorry for the late response.
