Re: Videomode 800x480

Hello, I`m doing video=3D0x0... to letFB_find_mode use my default video!
Yes I give you my vfb.c and .config! Thanks very much!
I found that only changing  the linelength, the visible resolution changes
too.

What arguments do you pass to fb_find_mode() in the driver? Probing all o=

f

these modes is not necessary.
