First, why don't you try increasing the font size of your
messages!! Don't get angry, just a joke. As for the kernel arguments,
you are on the right track. If you get a working screen with vmode:10
then first try booting up and issue a "man vmode" command. Read the
definitions for each mode and then decide which one is best for you.
Afterwards reboot and pass either of following arguments to the kernel:
append="video=atyfb:vmode:10,32"
append="video=atyfb:vmode:10,24"
video=atyfb:vmode:10,32
I give you the options with variations of syntax because I don't
remember which one is the correct one. The color bit depth is given
after a coma separating it from the vmode. That was your mistake,
different vmodes will not get you different color resolutions. But don't
forget to replace the 10 with the vmode that best meets your hardware.
Just on a side note, what kernel are you running? By using "atyfb" you
are using a frame buffer driver that will not give you accelerated
video. You can get a fresh new kernel and compile some of the ATI
modules into the kernel and thus get acceleration. I can't remember what
driver your computer would use, but would certainly be either the "r128"
driver or the "aty" one (not "atyfb"). And in order to get real
acceleration you also need latests XFree86 releases.
Try that and let me know how it goes. Sincerely,...
Juan.
