1. where is the /lib/firmware located ;in for example /usr/src/linux/lib/firmware or /usr/lib/firmware or elsewhere?
2.Could i use a pre-build EDID in that address the post gave and tweak it with an editor like Gvim and pass it to kernel using the info bellow; the resolution i am trying is [email protected]
