Xorg resolution with VGA Switch

[Aurélien PROVIN]

Hi,

I bought a VGA switch to switch some devices on one monitor.
But resolution of my X session is limited to 1024x768 instead of 1920x1200.
If I hotplug the switch when the X session is started in 1920x1200, it works.

Could you help me ?

Regards,

Aurelien
