Title: cgx modeid?
Post by: wawrzon on May 09, 2009, 07:01:12 PM

can anybody tell me what the specific ids are attached by cgx to display resolutions? do they depend on gfx card? i suspect bestmodeid doesnt returns the correct value on my p96 system, because mode ids are messed up. or maybe there is some online docs on the subject, i didnt find?

I don't know how the id numbers are assigned, but to find the id's of your screen modes, you may find the GetModeID utility that comes with Visage (http://aminet.net/gfx/show/Visage.lha) useful.

Don't remember exactly but they do differ. And they are different from system to system. I think they get created when you make new modes and every new mode gets the next free number. Different cards get different first number - or something like. As I ran at least 3 different cards at the same time the modes really were a mess!

@caius,zipper:
thanks. i thought my problems with sdl and amiblitz apps not able to open a screen could be modeid related, but now i arranged ids on my voodoo machine just as on a p4 one where said problems do not show up and it didnt help. also getmodeid returns same values for same resolutions on both. have to investigate further.
