Problem in clone mode with two display card

[Deepak Bhatia]

Hi Alex,

Yes, we are trying to use ATI Card and Intel Card at the same time for
different configurations using two monitors.
1. Clone
2. Expand
3. Independent

When we specify the i810 driver in the device section as Card1 and ati
driver in the device section as Card0, things are going fine.

But if replace i810 by intel in the device section, things are not
working. We thought that intel is the latest driver than i810.

Please suggest us what to do as currently we are sticking to i810.

Best Regards

Deepak Bhatia

Are you trying to use the intel card and the ati card at the same time?
