Public bug reported:
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
