Then the problem lies in a layer above the linux drivers. It would be nice to get the low level so you can do tap to click etc. Can you give me some pointers on where this would be. Or maybe were it should be. Next shouldn't the linux drivers then load last only if the ps2 ones don't work right now I don't think we order the way input drivers are tried I could be wrong. > > Next is there any fundamental reason why the vesa driver cannot change > > modes. > > Dumb Vesa design only allows mode changes in real mode, but there's a > patch for the kernel that uses vm86 to do that IIRC. Hmm I think X11 has a user mode module to do this does it make sense to bring that over or include the kernel patch in the directfb source.

I'm not sure what X11 does here in my case I think they use the intel driver for X. I've not looked at the X11 vesa driver in detail. Finally we need the monitor or lcd info is there a kernel driver for this already ?
