[Linux-fbdev-devel] vesafb and xres_virtual

[Paul F. <pa...@ga...>]

Hi all,
Perhaps someone can enlighten me. I've been ploughing through the vesafb 
source and various other bits (video.S in boot as well) and I see that 
the vesa driver supports changing the virtual y resolution but not the 
virtual x. I suspect there is a really good reason for this - possibly 
the real mode nature of BIOS calls or perhaps something to do with 
bytes_per_line and the console driver - but I am not sure. Would it be 
possible to allow virtual x resolutions to be set at startup? If not 
then can the authors please fix the rivafb driver for GeForce2 Go chips? 
:) I really need hardware x panning - it's for a demo that will boot and 
run off a floppy.

many thanks - and hoping to be able to contribute,

Paul.
