Yes, sure, but this cannot do anything like miroring or windows zooming, only standard static dual head. > >Also, i guess this would facilitate the memory > >management in dual head configurations. > > Yes, the driver would need to handle how the memory is shared. Yes, shared between both heads, but also between 2D and 3D, altough i don't know how DRI handles this right now. > > >In general, dual head configuration is pretty poor in the current X > >server, at least in the documented part.

Mmm, but you would need a fixed screen stride that is the sum of both heads, or something such. I guess using a virtual screen is the way to go, but there may be problems with regard to how apps (in particular desktop managers) handle it, i guess. > >I think that matrox did something such in their proprietary drivers. > > There are other proprietary drivers that have also done similar > functionality. However, I haven't seen anything in open source. Mmm, i would be interested in working on this, need to find some time though. Are there other people whow are interested in this also ?
